Installation and Upgrade Notes

This section includes the following topics:

Installation Notes

Upgrade Notes

Installation Notes

Caution If you enter only an IP address during set up, the Cisco DMS appliances cannot communicate with each other. Cisco DMS appliances will not work correctly without a DNS server. Please enter a fully-qualified domain name (FQDN).

To maintain network security, your DMM appliances and Video Portal appliances use digital certificates to communicate. These certificates use the DNS-routable hostname to identify each appliance uniquely. Therefore, you must enter the DNS-routable hostname for each appliance during setup when prompted to enter the fully-qualified domain name (FQDN) in AAI.

You must also configure each of your DMS appliances in AAI to point correctly to the DNS server for your network and configure that DNS server to associate the IP addresses that your DMS appliances use with the FQDNs that their digital certificates use.

When setting up your DMS 5.1. x appliances, do not use “Cisco” as the instance name for your Video Portal appliance. We reserve the use of the Cisco name for other purposes, and all deployments will fail if you use this instance name.

Upgrade Notes

You can upgrade from Cisco Digital Media System 5.0. x to 5.1. x . For more information, including requirements and procedures, see Upgrade Guide to Release 5.1.x for Cisco Digital Media System on Cisco.com.

For information about the hardware and software that Cisco DMS supports in this release, see the “Compatibility Matrix for Upgrading” section.

Important Notes

This section includes the following topics:

Low Memory Causes DMP 4305G Endpoints to Restart Automatically

Compatibility Limitations with Microsoft Internet Information Server (IIS)

Low Memory Causes DMP 4305G Endpoints to Restart Automatically

Rather than crashing when they run low on memory, DMPs are designed to restart automatically, which clears their memory and causes downtime of much less than 1 minute, as opposed to the lengthy downtime that a hard crash would cause. In the rare cases when DMPs do run out of memory and restart automatically, SWF files are almost always responsible. The known scenarios when this can occur are as follows:

The file size is greater than 500KB for your SWF file. Larger SWF files do work correctly in most cases, but we recommend as a best practice that you should always strive to use the smallest possible SWF files. Smaller files are far less likely to be burdensome to your DMPs.

Your SWF file uses bitmapped image files outside itself that have a very large file size, either individually or collectively. Any bitmapped image files that you use in the production of a SWF file should be small files. If a bitmapped file has a large file size, it is important for you to understand that merely reducing the height and width of its placeholder on your canvas in Adobe Flash (or any similar authoring tool that you might use to develop a SWF file) will not reduce the actual file size.

The web page that you are showing uses too many embedded SWF files.

Additionally, we recommend that you use the following guidelines when you create SWF files:

The resolution of the SWF can be up to 1920 x 1080 if the animations that are contained within the SWF are small and are restricted to a 640x480 region.

Avoid redraw of the whole screen in your Flash animation.

Multiple movements on different parts of the screen cause more slowdown than a concentrated movement.

The FLV recommended resolution should be 320x240.

Limitations That are Resolved in DMS Release 5.1.0

Cisco DMS 5.1.0 corrects many bugs from earlier releases, including the ones that Table 4 describes.

Table 4 Resolved Bugs

Defect ID

Description

CSCsq26076

The DMP 4400G has no sound after rotating the browser angle to 180 or 270 degrees.

CSCsj72828

When adding an asset to DSM, be sure that its name does not include any non-ASCII characters. Although DMS can store the asset successfully, its nonstandard filename prevents the content chooser in DMD from loading it. In addition, DMPs cannot play a video asset from any URL that contains non-ASCII characters.

CSCsk41444

DMD allows you to create more than one synchronized playlist in a presentation; however, DMPs support only one synchronized playlist.

CSCso76820

The Schedules > Play Now advanced task version status does not display in a popup window.

CSCsq39627

If you check the randomize option for a playlist in a DMD presentation, you cannot uncheck this option; therefore, if you open a presentation and the randomized option is unchecked and you save the presentation, the randomize option persists for the playlist.

CSCsq87168

You cannot change the URL in edit asset operation after you add a URL asset; however, you can change other parameters.

CSCsu30288

When you show a public playlist that contains multiple jpeg files, which you stored locally on your DMP, the playback is choppy.

CSCsu43970

Media library batch upload does not work properly when filenames contain spaces.

CSCsv02181

If you upgrade to Cisco DMS 5.0.2 from release 5.0 without first installing the license to use DMM-DSM 5.0, you are prevented after the upgrade from accessing the 5.0.2 versions of both DMM-DSM and DMM-ETV. Your DMM server shows an HTTP 500 error instead of DMM-DSM and an authorization error instead of DMM-ETV.

CSCsq57006

The DMP 4305G does not display correctly websites that have a User-Agent field in the HTTP header.

CSCsr47342

Video playback ends too soon on DMP 4300G endpoints, no matter whether the video asset is included in a playlist or embedded in a web page, if you have rotated the browser plane to 180 degrees or 270 degrees in DMPDM.

CSCsr97307

If you select the Flash 10 option instead of the Flash 9 option in DMPDM 5.0.2, Enterprise TV performance might be disrupted when you use any of these buttons on your remote control for DMPs:

Show IP

Mute

VOL

Any unassigned buttons

CSCsu03541

DMPs cannot successfully follow an HTTP 302 redirect that changes the destination for a Video URL. This means that DMPs cannot play a video whose URL has changed, until the Video URL value points directly to the actual, changed URL.

CSCsm62811

After you deploy and then update a video part that contains keywords, keyword searches for the video part no longer work.

Compatibility Limitations with Microsoft Internet Information Server (IIS)

DMPs that use firmware release 5.1. x are compatible with only one version of Microsoft Internet Information Server. That supported version is IIS 6.0 for Windows 2003 Enterprise.

If you do not have the supported IIS version but want your DMPs to retrieve assets from a webserver, we recommend that you use Apache instead of IIS.

Limitations and Restrictions

Review Table 5 before you begin working with Cisco DMS 5.1. x components. These are known limitations that will not be fixed, and there is not always a workaround.

Also, be sure to read the “Important Notes” section section for additional information.

DMP displays that are attached to your DMP 4300G endpoints show a white line on 4 sides when your playlists transition from playback of Shockwave Flash assets to playback of video assets.

Workaround None.

CSCso63214

dmm-doc

When its resources are limited, a DMP 4305G endpoint resets without a splash screen and without illuminating the red LED that should be visible through the chassis front grille because of limited resources.

Workaround Upgrade to a DMP 4400G which is more powerful and does not exhibit this behavior.

CSCso78514

dmm-doc

Using the local file option to add a media asset that is larger than 2G causes the upload menu to remain open indefinitely.

Workaround None. This is a browser limitation. We recommend that you upload a file that is smaller than 2G and that you use an external server for large files.

CSCsq62648

dmm-doc

DMP 4305G restarts after 15 seconds when playing the emergency_animated template.

Workaround None. This template is designed for the DMP 4400G. We recommend you do not play content on the DMP 4305G that is specific to the DMP 4400G.

The factory-default video settings are not optimized on DMEs, and encoded video might be too bright.

Workaround Modify the settings until you are satisfied with the result.

Digital Media Manager (DMM)

CSCsr81929

If DHCP fails during first boot and you choose “no” when prompted for a static IP address, the DMM appliance installation stalls after 20 minutes and is unrecoverable.

Workaround Reimage the server with DMS recovery CD.

Digital Signage Module (DMM-DSM) and Enterprise TV Module (DMM-ETV)

CSCsx98270

When a DMD presentation and an advanced task are scheduled to run back-to-back, playback of the presentation does not stop when it should.

Workaround Avoid scheduling an advanced task to run immediately after playback of a presentation.

CSCsy01884

A DMP restarts unexpectedly (5 percent of the time) if video playback is in progress when you simultaneously use a file transfer task to download assets to the DMP.

Workaround There are two methods to work around this problem. Before you use a file transfer application, run the “Stop All Applications” system task on each affected DMP. Alternatively, you can use Cisco DMS Content Distribution (DMS-CD) instead of the file transfer task.

CSCsy06650

The total file size value for a playlist is reset to “N/A.” This occurs after you switch to WAAS mode, but only if Enterprise TV uses an asset that the playlist includes.

Workaround None.

CSCsx97974

DMD prevents you from adding a URL to a nonvideo playlist.

Workaround Add the URL to your media library. Then, when you try again to populate the playlist, choose the URL entry that you saved to your media library, instead of trying to enter the URL manually.

CSCsx30269

The dashboard in DMM-DSM does not show scheduled tasks. This problem is limited to Microsoft Internet Explorer (MSIE) and seems to be solved when you restart MSIE. However, the behavior reoccurs again later.

Workaround Choose Tools > Internet Options in MSIE, and then click Settings on the General tab. Click Every visit to the page , and then click OK twice.

CSCsx94959

User role limitations do not apply to the Emergencies tab. Any DMM-DSM user can use it.

Workaround Consider very carefully which DMM-DSM users should have permission to work with your schedule and manage your DMP groups. Although all of the “Play in Future” features are suspended (for affected DMPs only) while a declared emergency is in progress, none of the “Play Now” features or “DMP Manager” features are suspended. Therefore, it is possible for a careless user or malicious user with sufficient permissions to start another event manually on the DMPs where an emergency message should play.

CSCsx51041

After you associate a ticker action in DMD with a box object whose width is greater than 1,600 pixels, and you configure the ticker to scroll instead of fade, playback performance suffers for non-video assets, such as Shockwave Flash animations, that the presentation should play.

Workaround Reduce the width of the box object in your design or configure the ticker to fade but not scroll.

CSCsx51546

DMD does not prevent you from adding video assets to a nonvideo playlist. Instead of showing a warning that it does not support this behavior, DMD removes the video asset silently from the playlist when you save the presentation.

Workaround Avoid adding videos to nonvideo playlists in DMD.

CSCsx67967

DMM-DSM does not prevent you from uploading to your media library two assets that use the identical filename but whose other attributes differ. After you do this, the content chooser for DMD shows only one of these two assets.

Workaround Change the filename for one of the files, and then upload it again to your media library.

CSCsx53256

The error messages are unclear in DMD when you use File > Save As to save a presentation with the identical name that a presentation template uses.

Workaround Avoid duplicating names for presentations and templates.

CSCsx19497

The workspace in DMD does not preview the text inside a box object when its vertical alignment value is set to “Bottom.” Although the preview feature fails in DMD, the presentation works as designed on the DMP displays where you show it.

Workaround None.

CSCsw35538

Cisco DMS Content Distribution (DMS-CD) features of DMM-DSM do not support nested DMP groups. DMS-CD functions as if this group structure is flat and does not autodelete old assets from DMPs that it misunderstands to be part of multiple DMP groups.

Workaround If local storage is full on DMPs that should receive a deployment from DMS-CD, and these DMPs are in nested groups, use Play Now to deploy a command immediately to delete the obsolete files from them. After this cleanup is finished, try again to provision the new assets from DMS-CD as a scheduled, future event.

CSCsw94849

Cisco DMS Content Distribution (DMS-CD) might disrupt playback performance temporarily on your DMP 4400G endpoints. The disruption affects multicast video streams, HD videos, Shockwave Flash animations, and image assets that these DMPs show on their attached DMP displays while simultaneously downloading newly provisioned, large assets. Videos might become fragmented (contain artifacts), drop frames, or cut out during playback. Shockwave Flash animations might play slowly. Images might redraw slowly. DMPs might restart unexpectedly, in rare instances. These behaviors affect the DMP 4400G due to a hardware resource limitation.

Workaround You can configure bandwidth restrictions in your WAN that should help to alleviate these symptoms or eliminate them completely, depending on the system load of each DMP. Follow the best practices for DMS-CD that are described on Cisco.com, in User Guide for Cisco Digital Media System 5.1.x .

CSCsy01792

Cisco DMS Content Distribution (DMS-CD) might cause a DMP to restart unexpectedly. This occurs if you make selections in DMM-DSM to provision assets to an external USB drive (usb_2) that is not actually attached to the DMP.

Workaround Before you try to provision assets to an external USB drive, verify that the drive exists and is attached to the DMP. Choose Digital Media Players > DMP Manager , and then check the “External Storage MB. (Total/Free)” value that pertains to this DMP. The value should not be blank.

CSCsw67738

After Cisco DMS Content Distribution (DMS-CD) adds or deletes files on an external USB drive that is attached to a DMP, the DMP might mount this drive as Read-Only or might not mount it at all. Content distribution to or from usb_2 sometimes corrupts the file system on drives from certain manufacturers. In our testing, we have seen this on Western Digital Passport drives 0.5 percent of the time and on Maxtor drives 70 percent of the time. We have removed Maxtor from our list of supported manufacturers.

Workaround Disconnect the USB drive from your DMP and reformat the USB drive to use FAT32 as its file system.

CSCsx39478

VoD playback does not stop immediately in Enterprise TV on DMP 4300G and DMP 4305G endpoints when you choose the VoD parent folder from the menu.

Workaround None.

CSCsw89590

When you make selections in DMM-ETV to show an on-screen PIN that mobile phone users can use to authenticate their phones for emulation of the DMP remote control, the PIN might take as long as 2 minutes to appear on-screen.

Workaround Wait 2 minutes.

CSCsy01751

The video preview feature for Enterprise TV sometimes shows the wrong preview. Also, you are prevented from switching from the preview to the full-screen video. Instead of full-screen video, you might see that a small black rectangle loads in the upper right corner of the DMP display. Furthermore, if you press the Show IP button on a DMP remote control, an empty box is loaded instead of the IP address. These behaviors affect a DMP 4400G endpoint that has been running Enterprise TV for several days.

Workaround Redeploy the task to start Enterprise TV.

CSCsk30744

Current CDETS state is Duplicate

You cannot save a presentation that is the same name as the presentation template.

Workaround: None.

CSCsl97280

In an ACNS/DMS integration, if an ACNS channel is deleted while still scheduled in DMS, the DMS playlist cannot be deleted in DMM-DSM.

Workaround Create the set of the channels that are used to work with DMM-DSM, and do not delete them. To remove a channel from ACNS, complete these steps. Before deletion, remove all schedules that are assigned to particular channel (past/current/future). Remove channel from ACNS only after you have removed the schedules.

CSCso83562

On the Play in Future tab, scheduling monthly and yearly recurring jobs during a leap year results in scheduling anomalies for jobs that occur during the month of February in subsequent months and years.

Workaround None.

CSCsq72364

The first time you open a new, blank landscape template, the resolution defaults to portrait (768 x 1366).

Workaround Click the Portrait tab; then, click the Landscape tab.

CSCsu27675

Current CDETS state is Junked

In Firefox 3, some parts of the web-based DMM-DSM user interface are misaligned and do not work properly.

Workaround: Use Firefox 2; we do not support Firefox 3.

CSCsu32056

When using Virtua presentation template in DMD, with the effect of the scrolling ticker is changed to scroll (left) - The scrolling ticker freezes on flash slide transition.

Workaround Avoid changing scroll effect in the DMD virtual presentation template.

CSCsu49007

Current CDETS status is Closed

If you upgrade or downgrade the firmware for a DMP group that contains more than 20 DMPs while those same DMPs are playing a DMD presentation (which uses video and Shockwave Flash assets), some of the affected DMPs might not restart automatically and their upgrade might not be completed. When this happens, you cannot access the affected DMPs through port 7777 or port 6666. However you can ping them and you can see a green light through the front grille of their chassis.

Workaround: Before upgrading any DMP group that contains more than 20 DMPs, complete these steps to clear the content being played:

1. In DMM-DSM, use the Advanced Tasks feature to create a new DMP Startup URL task that will clear the startup URL and restart your DMP:

For the task name, enter: Startup URL - Empty & Restart .

For the description, enter: Startup URL - Empty & Restart .

Do not enter anything for the Video URL.

Do not enter anything for the Browser URL.

Check the Reboot Necessary check box.

2. Save your work.

3. Under the Schedules tab, use the Play Now feature to submit the “Startup URL - Empty & Restart” task to your DMPs.

4. After your DMPs have restarted, submit the firmware upgrade or downgrade to no more than 20 of them at one time.

5. After the upgrade or downgrade is finished and the affected DMPs have all restarted automatically, use the Play Now or Play in Future method to run an advanced task on your DMPs to populate their Startup URL.

Is it compulsory or forbidden for us to disclose CSCsq62657 and CSCsj09611?

Digital Media Player

CSCsx57321

The Internal Storage page in DMPDM might show that the DMP 4300G or DMP 4305G file system is Read-Write, instead of Read-Only. This occurs after cycling a DMP (turning its power off and then on), which can sometimes cause its file system to mount local volumes incorrectly.

Workaround Use the Restart DMP page in DMPDM to soft-reset your DMP and restore normal permissions.

CSCsx45397

While showing a presentation that combines Shockwave Flash (SWF) assets and video assets (unicast or multicast streams), DMP playback of the video is choppy. This occurs only when a DMP starts, while it is loading SWF assets into memory, and is the result of limited CPU capacity.

Workaround None.

CSCsw36650

DMP displays might go black for as long as 3 seconds when playback is transitioning from one video asset to another video asset.

Workaround To reduce the duration of the black screen interval between two videos, you can use DMM-DSM to turn off the failover URL for a DMP.

CSCsx27295

After you use a DMM-DSM system task to disable DMP failover, there is no indication in DMPDM that failover is disabled.

Workaround If you cannot use DMPDM successfully to enable DMP failover, check in to see if failover is disabled for that DMP in DMM-DSM.

CSCsw49508

DMPDM becomes unresponsive after you enter the wrong IP address to identify the DMM appliance that you use for centralized management. This happens only after you incorrectly enter the IP address of your DMM appliance.

Workaround Restart the DMP and, within 30 seconds, enter either 127.0.0.1 or the correct IP address for your DMM appliance.

CSCsq39957

If you play a DMD presentation on the DMP 4400G or DMP 4305G and then play a playlist, the videos will not appear full screen because the DMD-generated application changes the video dimensions.

Workaround Change the video settings back to full screen, and restart the DMP.

CSCsq62685

Current CDETS status is Closed

When you submit an HTTP pulling task with a DMD presentation to a DMP, the DMP continues to play the currently playing presentation while pulling content.

Workaround: Determine whether you want to stop the playing presentation before you submit an HTTP pulling task.

CSCsr49869

Video performance becomes choppy on DMP 4300G and DMP 4305G endpoints while they are downloading updated RSS data for tickers.

Workaround None. This is the result of a processor limitation.

CSCsr90758

If you select the Flash 10 option instead of the Flash 9 option in DMPDM 5.0.2, DMP 4400G endpoints might exhibit choppy playback performance when playing Shockwave Flash assets.

Workaround Choose the Flash 9 option.

CSCsu03553

When a DMP uses Flash 10, the background color on its attached DMP display changes to white after 7 hours of continuous playback for any SWF object. After this same interval, the DMP remote control has no effect when you try to use its features to mute audio, adjust audio volume, or show which IP address the DMP is using.

Workaround None.

CSCsu11596

Current CDETS status is Unreproducible

A DMP 4400G might stop responding to the volume control buttons on its remote control if you use the remote control to adjust the audio volume levels for assets that you are playing from local storage.

Workaround: Do not use your remote control in this way with a DMP 4400G while any of its locally stored assets are playing.

CSCsu87484

EDCS text leaves it unclear whether this is a limitation in DMM or if it is specific to the 4305. Which is it?

DMP 4305 endpoints cannot successfully transmit RS-232 commands to control SunBrite 46" all-weather displays.

Workaround None.

DMS-Admin

Enterprise TV

Video Portal

CSCsw43748

When Cisco Video Portal plays a QuickTime video, the video is not centered in the browser. There is a white or black space under the video.

Workaround None.

CSCsx94831

The Windows Media VoD video slider does not work in Firefox.

Workaround If you require this feature, use another supported browser than Firefox.

CSCsy01889

When you use Microsoft Internet Explorer 6.0 to log in to Cisco Video Portal, you cannot press the Tab key to move your cursor to the Password field.

Workaround Click in the Password field to move your cursor to it.

CSCsx80329

A Cisco Video Portal that uses Windows Media or QuickTime for video might reload constantly on client systems that use Firefox.

Workaround Restart the client system.

CSCsk28257

Cisco Video Portal client systems with low memory might hang when viewing live or VoD events that include more than 100 synchronized slides because each slide requires approximately 2MB of memory.

Workaround Increase memory on the client system.

CSCsq95031

Synchronized slides for Cisco Video Portal are not backed up when you back up the DMM appliance and not available after you restore from this backup.

Workaround None.

Updates and Errata for Printed Documentation

Online-only documents on Cisco.com for Cisco DMS are updated as needed, and we recommend that you check Cisco.com regularly for updates.

This section describes errors and omissions in the printed documentation for Cisco DMS 5.1. x , which will be corrected in future printings.

Remote Control Quick Start Guide for Cisco Digital Media Players

Mounting Kit Assembly Guide for Cisco Digital Media Players

Quick Start Guide for Cisco Digital Media Player (4305G and 4400G)

Remote Control Quick Start Guide for Cisco Digital Media Players

In some printings, the “Requirements and Limitations” section states incorrectly that the “Cisco Digital Media Player (DMP) 4400G devices, and 4305G devices after July 2008, ship with a remote control.” The remote control is an optional item that you must purchase separately.

Mounting Kit Assembly Guide for Cisco Digital Media Players

In some printings, Cisco product numbers are wrong for mount kits.

Any use of “69-180 2 -01” is incorrect. The correct part number is “DMP-PRCASE- 4305 -S1.”

Any use of “69-180 3 -01” is incorrect. The correct part number is “DMP-PRCASE- 4400 -S1.”

Quick Start Guide for Cisco Digital Media Player (4305G and 4400G)

Some printings of these two guides contain identical errors:

Quick Start Guide for Cisco Digital Media Player 4305G

Quick Start Guide for Cisco Digital Media Player 4400G

The errors are as follows:

The Concepts text on page 3 mentions “protective case” accessories for DMPs, which discourage tampering and prevent theft. The accessory category was renamed after these guides were printed. The category name is now “mount kit.”

Also because the accessory category was renamed, the topic “Learning About the Protective Case for DMPs” became invalidated in multiple ways after these guides were printed:

– The topic heading should say “Learning About the Mounting Kit for DMPs.”

– The topic text mischaracterizes the title for mount kit assembly documentation. The correct title is Mounting Kit Assembly Guide for Cisco Digital Media Players .

Any use of “69-180 2 -01” is incorrect. The correct part number is “DMP-PRCASE- 4305 -S1.”

Any use of “69-180 3 -01” is incorrect. The correct part number is “DMP-PRCASE- 4400 -S1.”

Table 4 Resolved Bugs
Defect ID	Description
CSCsq26076	The DMP 4400G has no sound after rotating the browser angle to 180 or 270 degrees.
CSCsj72828	When adding an asset to DSM, be sure that its name does not include any non-ASCII characters. Although DMS can store the asset successfully, its nonstandard filename prevents the content chooser in DMD from loading it. In addition, DMPs cannot play a video asset from any URL that contains non-ASCII characters.
CSCsk41444	DMD allows you to create more than one synchronized playlist in a presentation; however, DMPs support only one synchronized playlist.
CSCso76820	The Schedules > Play Now advanced task version status does not display in a popup window.
CSCsq39627	If you check the randomize option for a playlist in a DMD presentation, you cannot uncheck this option; therefore, if you open a presentation and the randomized option is unchecked and you save the presentation, the randomize option persists for the playlist.
CSCsq87168	You cannot change the URL in edit asset operation after you add a URL asset; however, you can change other parameters.
CSCsu30288	When you show a public playlist that contains multiple jpeg files, which you stored locally on your DMP, the playback is choppy.
CSCsu43970	Media library batch upload does not work properly when filenames contain spaces.
CSCsv02181	If you upgrade to Cisco DMS 5.0.2 from release 5.0 without first installing the license to use DMM-DSM 5.0, you are prevented after the upgrade from accessing the 5.0.2 versions of both DMM-DSM and DMM-ETV. Your DMM server shows an HTTP 500 error instead of DMM-DSM and an authorization error instead of DMM-ETV.
CSCsq57006	The DMP 4305G does not display correctly websites that have a User-Agent field in the HTTP header.
CSCsr47342	Video playback ends too soon on DMP 4300G endpoints, no matter whether the video asset is included in a playlist or embedded in a web page, if you have rotated the browser plane to 180 degrees or 270 degrees in DMPDM.
CSCsr97307	If you select the Flash 10 option instead of the Flash 9 option in DMPDM 5.0.2, Enterprise TV performance might be disrupted when you use any of these buttons on your remote control for DMPs: Show IP Mute VOL Any unassigned buttons
CSCsu03541	DMPs cannot successfully follow an HTTP 302 redirect that changes the destination for a Video URL. This means that DMPs cannot play a video whose URL has changed, until the Video URL value points directly to the actual, changed URL.
CSCsm62811	After you deploy and then update a video part that contains keywords, keyword searches for the video part no longer work.

Table 5 Limitations and Restrictions in Cisco DMS 5.0
Identifier	Component	Description
Digital Media Player
—	—	Send DMP commands to DMPs in intervals of no fewer than 4 seconds between commands.
CSCsk22719	dmm-doc	All services are brought down when you start a firmware upgrade on the DMP 4305G. Workaround Manually restart the DMP.
CSCsq29816	dmm-doc	Errors occur on DMP 4400G and DMP 4305G endpoints when video links are configured as the startup URL. Workaround None. Use the video URL instead.
CSCsq64982	dmm-doc	Video stops playing on the DMP 4305G when you insert a flash drive into the USB interface. Workaround Do not insert a flash drive when the DMP 4305G is active. Only insert the flash drive when the DMP is idle, and then restart.
Digital Signage Module (DMM-DSM)
—	—	If the DMM appliance goes down temporarily or restarts, you must ensure that replication between the DMM and Video Portal has resumed by verifying that the “Replication to Digital Media Manager: Working” message displays in the Video Portal AAI.
CSCsw44817	—	DMP displays that are attached to your DMP 4300G endpoints show a white line on 4 sides when your playlists transition from playback of Shockwave Flash assets to playback of video assets. Workaround None.
CSCso63214	dmm-doc	When its resources are limited, a DMP 4305G endpoint resets without a splash screen and without illuminating the red LED that should be visible through the chassis front grille because of limited resources. Workaround Upgrade to a DMP 4400G which is more powerful and does not exhibit this behavior.
CSCso78514	dmm-doc	Using the local file option to add a media asset that is larger than 2G causes the upload menu to remain open indefinitely. Workaround None. This is a browser limitation. We recommend that you upload a file that is smaller than 2G and that you use an external server for large files.
CSCsq62648	dmm-doc	DMP 4305G restarts after 15 seconds when playing the emergency_animated template. Workaround None. This template is designed for the DMP 4400G. We recommend you do not play content on the DMP 4305G that is specific to the DMP 4400G.

Table 6 Open Caveats for Cisco DMS 5.1.x
Identifier	Description
Digital Media Encoders (DME)
CSCsx80200	The factory-default video settings are not optimized on DMEs, and encoded video might be too bright. Workaround Modify the settings until you are satisfied with the result.
Digital Media Manager (DMM)
CSCsr81929	If DHCP fails during first boot and you choose “no” when prompted for a static IP address, the DMM appliance installation stalls after 20 minutes and is unrecoverable. Workaround Reimage the server with DMS recovery CD.
Digital Signage Module (DMM-DSM) and Enterprise TV Module (DMM-ETV)
CSCsx98270	When a DMD presentation and an advanced task are scheduled to run back-to-back, playback of the presentation does not stop when it should. Workaround Avoid scheduling an advanced task to run immediately after playback of a presentation.
CSCsy01884	A DMP restarts unexpectedly (5 percent of the time) if video playback is in progress when you simultaneously use a file transfer task to download assets to the DMP. Workaround There are two methods to work around this problem. Before you use a file transfer application, run the “Stop All Applications” system task on each affected DMP. Alternatively, you can use Cisco DMS Content Distribution (DMS-CD) instead of the file transfer task.
CSCsy06650	The total file size value for a playlist is reset to “N/A.” This occurs after you switch to WAAS mode, but only if Enterprise TV uses an asset that the playlist includes. Workaround None.
CSCsx97974	DMD prevents you from adding a URL to a nonvideo playlist. Workaround Add the URL to your media library. Then, when you try again to populate the playlist, choose the URL entry that you saved to your media library, instead of trying to enter the URL manually.
CSCsx30269	The dashboard in DMM-DSM does not show scheduled tasks. This problem is limited to Microsoft Internet Explorer (MSIE) and seems to be solved when you restart MSIE. However, the behavior reoccurs again later. Workaround Choose Tools > Internet Options in MSIE, and then click Settings on the General tab. Click Every visit to the page , and then click OK twice.
CSCsx94959	User role limitations do not apply to the Emergencies tab. Any DMM-DSM user can use it. Workaround Consider very carefully which DMM-DSM users should have permission to work with your schedule and manage your DMP groups. Although all of the “Play in Future” features are suspended (for affected DMPs only) while a declared emergency is in progress, none of the “Play Now” features or “DMP Manager” features are suspended. Therefore, it is possible for a careless user or malicious user with sufficient permissions to start another event manually on the DMPs where an emergency message should play.
CSCsx51041	After you associate a ticker action in DMD with a box object whose width is greater than 1,600 pixels, and you configure the ticker to scroll instead of fade, playback performance suffers for non-video assets, such as Shockwave Flash animations, that the presentation should play. Workaround Reduce the width of the box object in your design or configure the ticker to fade but not scroll.
CSCsx51546	DMD does not prevent you from adding video assets to a nonvideo playlist. Instead of showing a warning that it does not support this behavior, DMD removes the video asset silently from the playlist when you save the presentation. Workaround Avoid adding videos to nonvideo playlists in DMD.
CSCsx67967	DMM-DSM does not prevent you from uploading to your media library two assets that use the identical filename but whose other attributes differ. After you do this, the content chooser for DMD shows only one of these two assets. Workaround Change the filename for one of the files, and then upload it again to your media library.
CSCsx53256	The error messages are unclear in DMD when you use File > Save As to save a presentation with the identical name that a presentation template uses. Workaround Avoid duplicating names for presentations and templates.
CSCsx19497	The workspace in DMD does not preview the text inside a box object when its vertical alignment value is set to “Bottom.” Although the preview feature fails in DMD, the presentation works as designed on the DMP displays where you show it. Workaround None.
CSCsw35538	Cisco DMS Content Distribution (DMS-CD) features of DMM-DSM do not support nested DMP groups. DMS-CD functions as if this group structure is flat and does not autodelete old assets from DMPs that it misunderstands to be part of multiple DMP groups. Workaround If local storage is full on DMPs that should receive a deployment from DMS-CD, and these DMPs are in nested groups, use Play Now to deploy a command immediately to delete the obsolete files from them. After this cleanup is finished, try again to provision the new assets from DMS-CD as a scheduled, future event.
CSCsw94849	Cisco DMS Content Distribution (DMS-CD) might disrupt playback performance temporarily on your DMP 4400G endpoints. The disruption affects multicast video streams, HD videos, Shockwave Flash animations, and image assets that these DMPs show on their attached DMP displays while simultaneously downloading newly provisioned, large assets. Videos might become fragmented (contain artifacts), drop frames, or cut out during playback. Shockwave Flash animations might play slowly. Images might redraw slowly. DMPs might restart unexpectedly, in rare instances. These behaviors affect the DMP 4400G due to a hardware resource limitation. Workaround You can configure bandwidth restrictions in your WAN that should help to alleviate these symptoms or eliminate them completely, depending on the system load of each DMP. Follow the best practices for DMS-CD that are described on Cisco.com, in User Guide for Cisco Digital Media System 5.1.x .
CSCsy01792	Cisco DMS Content Distribution (DMS-CD) might cause a DMP to restart unexpectedly. This occurs if you make selections in DMM-DSM to provision assets to an external USB drive (usb_2) that is not actually attached to the DMP. Workaround Before you try to provision assets to an external USB drive, verify that the drive exists and is attached to the DMP. Choose Digital Media Players > DMP Manager , and then check the “External Storage MB. (Total/Free)” value that pertains to this DMP. The value should not be blank.
CSCsw67738	After Cisco DMS Content Distribution (DMS-CD) adds or deletes files on an external USB drive that is attached to a DMP, the DMP might mount this drive as Read-Only or might not mount it at all. Content distribution to or from usb_2 sometimes corrupts the file system on drives from certain manufacturers. In our testing, we have seen this on Western Digital Passport drives 0.5 percent of the time and on Maxtor drives 70 percent of the time. We have removed Maxtor from our list of supported manufacturers. Workaround Disconnect the USB drive from your DMP and reformat the USB drive to use FAT32 as its file system.
CSCsx39478	VoD playback does not stop immediately in Enterprise TV on DMP 4300G and DMP 4305G endpoints when you choose the VoD parent folder from the menu. Workaround None.
CSCsw89590	When you make selections in DMM-ETV to show an on-screen PIN that mobile phone users can use to authenticate their phones for emulation of the DMP remote control, the PIN might take as long as 2 minutes to appear on-screen. Workaround Wait 2 minutes.
CSCsy01751	The video preview feature for Enterprise TV sometimes shows the wrong preview. Also, you are prevented from switching from the preview to the full-screen video. Instead of full-screen video, you might see that a small black rectangle loads in the upper right corner of the DMP display. Furthermore, if you press the Show IP button on a DMP remote control, an empty box is loaded instead of the IP address. These behaviors affect a DMP 4400G endpoint that has been running Enterprise TV for several days. Workaround Redeploy the task to start Enterprise TV.
CSCsk30744	Current CDETS state is Duplicate You cannot save a presentation that is the same name as the presentation template. Workaround: None.
CSCsl97280	In an ACNS/DMS integration, if an ACNS channel is deleted while still scheduled in DMS, the DMS playlist cannot be deleted in DMM-DSM. Workaround Create the set of the channels that are used to work with DMM-DSM, and do not delete them. To remove a channel from ACNS, complete these steps. Before deletion, remove all schedules that are assigned to particular channel (past/current/future). Remove channel from ACNS only after you have removed the schedules.
CSCso83562	On the Play in Future tab, scheduling monthly and yearly recurring jobs during a leap year results in scheduling anomalies for jobs that occur during the month of February in subsequent months and years. Workaround None.
CSCsq72364	The first time you open a new, blank landscape template, the resolution defaults to portrait (768 x 1366). Workaround Click the Portrait tab; then, click the Landscape tab.
CSCsu27675	Current CDETS state is Junked In Firefox 3, some parts of the web-based DMM-DSM user interface are misaligned and do not work properly. Workaround: Use Firefox 2; we do not support Firefox 3.
CSCsu32056	When using Virtua presentation template in DMD, with the effect of the scrolling ticker is changed to scroll (left) - The scrolling ticker freezes on flash slide transition. Workaround Avoid changing scroll effect in the DMD virtual presentation template.
CSCsu49007	Current CDETS status is Closed If you upgrade or downgrade the firmware for a DMP group that contains more than 20 DMPs while those same DMPs are playing a DMD presentation (which uses video and Shockwave Flash assets), some of the affected DMPs might not restart automatically and their upgrade might not be completed. When this happens, you cannot access the affected DMPs through port 7777 or port 6666. However you can ping them and you can see a green light through the front grille of their chassis. Workaround: Before upgrading any DMP group that contains more than 20 DMPs, complete these steps to clear the content being played: 1. In DMM-DSM, use the Advanced Tasks feature to create a new DMP Startup URL task that will clear the startup URL and restart your DMP: For the task name, enter: Startup URL - Empty & Restart . For the description, enter: Startup URL - Empty & Restart . Do not enter anything for the Video URL. Do not enter anything for the Browser URL. Check the Reboot Necessary check box. 2. Save your work. 3. Under the Schedules tab, use the Play Now feature to submit the “Startup URL - Empty & Restart” task to your DMPs. 4. After your DMPs have restarted, submit the firmware upgrade or downgrade to no more than 20 of them at one time. 5. After the upgrade or downgrade is finished and the affected DMPs have all restarted automatically, use the Play Now or Play in Future method to run an advanced task on your DMPs to populate their Startup URL.
Is it compulsory or forbidden for us to disclose CSCsq62657 and CSCsj09611? Digital Media Player
CSCsx57321	The Internal Storage page in DMPDM might show that the DMP 4300G or DMP 4305G file system is Read-Write, instead of Read-Only. This occurs after cycling a DMP (turning its power off and then on), which can sometimes cause its file system to mount local volumes incorrectly. Workaround Use the Restart DMP page in DMPDM to soft-reset your DMP and restore normal permissions.
CSCsx45397	While showing a presentation that combines Shockwave Flash (SWF) assets and video assets (unicast or multicast streams), DMP playback of the video is choppy. This occurs only when a DMP starts, while it is loading SWF assets into memory, and is the result of limited CPU capacity. Workaround None.
CSCsw36650	DMP displays might go black for as long as 3 seconds when playback is transitioning from one video asset to another video asset. Workaround To reduce the duration of the black screen interval between two videos, you can use DMM-DSM to turn off the failover URL for a DMP.
CSCsx27295	After you use a DMM-DSM system task to disable DMP failover, there is no indication in DMPDM that failover is disabled. Workaround If you cannot use DMPDM successfully to enable DMP failover, check in to see if failover is disabled for that DMP in DMM-DSM.
CSCsw49508	DMPDM becomes unresponsive after you enter the wrong IP address to identify the DMM appliance that you use for centralized management. This happens only after you incorrectly enter the IP address of your DMM appliance. Workaround Restart the DMP and, within 30 seconds, enter either 127.0.0.1 or the correct IP address for your DMM appliance.
CSCsq39957	If you play a DMD presentation on the DMP 4400G or DMP 4305G and then play a playlist, the videos will not appear full screen because the DMD-generated application changes the video dimensions. Workaround Change the video settings back to full screen, and restart the DMP.
CSCsq62685	Current CDETS status is Closed When you submit an HTTP pulling task with a DMD presentation to a DMP, the DMP continues to play the currently playing presentation while pulling content. Workaround: Determine whether you want to stop the playing presentation before you submit an HTTP pulling task.
CSCsr49869	Video performance becomes choppy on DMP 4300G and DMP 4305G endpoints while they are downloading updated RSS data for tickers. Workaround None. This is the result of a processor limitation.
CSCsr90758	If you select the Flash 10 option instead of the Flash 9 option in DMPDM 5.0.2, DMP 4400G endpoints might exhibit choppy playback performance when playing Shockwave Flash assets. Workaround Choose the Flash 9 option.
CSCsu03553	When a DMP uses Flash 10, the background color on its attached DMP display changes to white after 7 hours of continuous playback for any SWF object. After this same interval, the DMP remote control has no effect when you try to use its features to mute audio, adjust audio volume, or show which IP address the DMP is using. Workaround None.
CSCsu11596	Current CDETS status is Unreproducible A DMP 4400G might stop responding to the volume control buttons on its remote control if you use the remote control to adjust the audio volume levels for assets that you are playing from local storage. Workaround: Do not use your remote control in this way with a DMP 4400G while any of its locally stored assets are playing.
CSCsu87484	EDCS text leaves it unclear whether this is a limitation in DMM or if it is specific to the 4305. Which is it? DMP 4305 endpoints cannot successfully transmit RS-232 commands to control SunBrite 46" all-weather displays. Workaround None.

Video Portal
CSCsw43748	When Cisco Video Portal plays a QuickTime video, the video is not centered in the browser. There is a white or black space under the video. Workaround None.
CSCsx94831	The Windows Media VoD video slider does not work in Firefox. Workaround If you require this feature, use another supported browser than Firefox.
CSCsy01889	When you use Microsoft Internet Explorer 6.0 to log in to Cisco Video Portal, you cannot press the Tab key to move your cursor to the Password field. Workaround Click in the Password field to move your cursor to it.
CSCsx80329	A Cisco Video Portal that uses Windows Media or QuickTime for video might reload constantly on client systems that use Firefox. Workaround Restart the client system.
CSCsk28257	Cisco Video Portal client systems with low memory might hang when viewing live or VoD events that include more than 100 synchronized slides because each slide requires approximately 2MB of memory. Workaround Increase memory on the client system.
CSCsq95031	Synchronized slides for Cisco Video Portal are not backed up when you back up the DMM appliance and not available after you restore from this backup. Workaround None.
