New Software Features and Software Changes in Release 2.4.0

Table 3 shows new software features and changes in software functionality introduced in system software release 2.4.0.

Table 3 New Software Features and Software Modifications in System Software Release 2.4.0

Module/Feature
Description of Change

Improved software installation and upgrade

Release 2.4.0 features the following changes to software installation and upgrade:

The installation program runs exclusively on the SPE (it does not require a separate PC). As a result, the installation program can be accessed remotely through Terminal Services Client. (If you attempt to run the installation program on a PC, it will not work, and an error message will be displayed.)

The installation program presents a progress bar and dialog boxes so that users can monitor its status.

Remote upgrade of multiple cards in the chassis is supported. For example, the installation program can be remotely accessed to upgrade ICS System Manager on the SPE running System Manager and ICS Core Software on another SPE.

The installation program can be run from a USB CD-ROM attached to an SPE or can be downloaded from CCO and run directly from the SPE.

The installation program does not place any restrictions on SPE IP addresses.

The installation program does not require that the chassis be disconnected from the network.

The installation program supports the installation of bundled service packs and hot fixes.

The installation program makes it possible to change the host name or the date and time on SPEs.

The installation program makes it possible to convert an SPE with ICS Core Software installed to an SPE running System Manager.


Limitations and Restrictions

This section describes known issues with the Cisco ICS 7750 and products that you are likely to use with the Cisco ICS 7750. This section provides information on these topics:

Installing Software on SPEs

Changing the Host Name of the SPE Running System Manager

SSP Error Messages

Removing SPEs

Backing Up MRPs Which Have Flash Memory

Configuring Cisco ICS 7750 Gateways in Cisco CallManager

Cisco IP Phone Reconfiguration Following SPE Replacement or Change in SPE IP Address

Providing Backup Power

Connecting to the Catalyst 3524-PWR XL 10/100 Inline-Power Ports

Installing Software on SPEs

Do not install Cisco Unity Voice Messaging on the SPE running System Manager, and do not install ICS System Manager on an SPE on which Cisco Unity Voice Messaging is installed. The Cisco ICS 7750 does not support the use of both Cisco Unity Voice Messaging and ICS System Manager on the same SPE.

In addition, if you intend to install or upgrade software on an SPE where Cisco Unity Voice Messaging is running, be sure to first stop Unity services running on that SPE.

The following text will be displayed if you attempt to upgrade or install software on an SPE on which Cisco Unity Voice Messaging is running:

Perform the following steps to stop the services on any SPE running Cisco Unity Voice 
Messaging before continuing with the installation.

1. Right mouse-click on the Cisco Unity Voice Messaging icon in the system tray, and 
select Stop Unity in the pop-up menu.
2. To open Service Control Manager, click Start, point to Programs, and point to 
Administrative Tools and click Services.
3. In the Services window, right mouse-click on Microsoft Exchange Information Store 
service, and select Stop from the pop-up menu.
4. Click Yes to confirm and close the Stop Other Services window.

WARNING: Failure to stop the above services on an SPE running Cisco Unity Voice Messaging 
can cause installation errors.

Do you want to continue with the installation?

Changing the Host Name of the SPE Running System Manager

The computer name (also known as the host name) of an SPE running System Manager can be changed only if no applications have been installed on the SPE since it left the factory. For example, if you install Cisco CallManager on the SPE running System Manager, the only way to change its host name is to reimage it.

To change the host name of an SPE running System Manager, follow the practices and procedures in the "Operating the Cisco ICS 7750" chapter of the Cisco ICS 7750 Installation and Configuration Guide.

SSP Error Messages

If you are using Cisco IOS 12.0(5)WC2b or 12.0(5)WC5 on the SSP, and if you are monitoring the system through a console connection to the SAP, error messages similar to the following might be generated as the SSP boots:

% error opening tftp://255.255.255.255/cisconet.cfg (Time out) 
% error opening tftp://255.255.255.255/router-confg (Time out)
% error opening tftp://255.255.255.255/ciscortr.cfg (Time out)

This is an expected condition. The system will continue to operate normally without any external intervention.

Removing SPEs

Before removing an operational SPE from the chassis, be sure to use ICSConfig or the Windows interface to shut it down (by clicking Start > Shutdown). This step is strongly recommended for the following reason: if Microsoft SQL Server was running on the SPE when it was removed from the chassis, at the next startup of that SPE, Microsoft SQL Server will require a long recovery period, during which certain Cisco ICS 7750 services and applications might have difficulty connecting to their respective databases.


Note For additional complete card removal instructions, refer to Cisco ICS 7750 FRU Installation and Replacement.


Backing Up MRPs Which Have Flash Memory

MRPs with onboard flash memory (the MRP300, MRP3-8FXS, and MRP3-16FXS) cannot be backed up using the ICS System Manager Backup utility. You must back up the configuration files for these cards manually.

Configuring Cisco ICS 7750 Gateways in Cisco CallManager

When configuring gateways in Cisco CallManager, the MRP300, MRP3-8FXS, and the MRP3-16FXS will not be available on the CallManager Gateway page. However, until this problem is corrected in Cisco CallManager, you can still add and configure these gateways in Cisco CallManager by substituting a known gateway for the gateway which is missing, as follows:

When configuring ICS77XX-MRP3xx, choose ICS77XX-MRP2xx

When configuring ICS77XX-MRP3-8FXS, choose ICS77XX-ASI81

When configuring ICS77XX-MRP3-16FXS, choose ICS77XX-ASI160

Cisco IP Phone Reconfiguration Following SPE Replacement or Change in SPE IP Address

If you remove and replace the SPE that is running Cisco CallManager or change its IP address, Cisco IP Phones connected to the Cisco ICS 7750 do not automatically register with the SPE, because the SPE has a different IP address.

Complete the following steps to update connected Cisco IP Phones:


Step 1 Access Cisco CallManager. (Refer to the "Accessing the System" section in the "Operating the Cisco ICS 7750" chapter of the Cisco ICS 7750 Installation and Configuration Guide for instructions.)

Step 2 Choose System > Cisco CallManager Group.

The Cisco CallManager Group Configuration page opens.

Step 3 In the pane on the left side of the window, click Default.

The screen refreshes, displaying the Default Cisco CallManager Group.


Caution Restarting devices causes them to drop calls.

Step 4 Click Reset Devices.


Providing Backup Power

If there is a commercial power failure and if data is being written to the SPE hard disk when power is lost, that data might be unrecoverable. In addition, all calls being processed by the system are dropped, and records associated with those calls are lost.


Caution We strongly recommend that you purchase an uninterruptible power supply (UPS) to provide backup power to the Cisco ICS 7750.

Connecting to the Catalyst 3524-PWR XL 10/100 Inline-Power Ports

For instructions on how to properly configure the Catalyst 3524-PWR XL for inline power, refer to the "Connecting IP Phones" chapter in the Cisco IP Telephony QoS Design Guide.


Caution A Catalyst 3524-PWR XL 10/100 port needs up to 10 seconds to initially detect, power, and link to a Cisco IP Phone. If you disconnect the Cisco IP Phone before the link has been established, you must wait 10 seconds before connecting another network device (other than another Cisco IP Phone) to that switch port. Failure to do so can result in damage to that network device.

Important Notes

This section describes issues related to sending voice traffic over an IP network.

Voice Over IP

Voice over IP (VoIP) enables a Cisco ICS 7750 to carry voice traffic (for example, telephone calls and faxes) over an IP network. VoIP is primarily a software feature; however, to support this feature, a Cisco ICS 7750 must be equipped with an MRP containing at least one VIC or VWIC, or the Cisco ICS 7750 must be connected to a voice-capable router or gateway. The LAN/WAN multiservice routing capabilities available on these cards provides analog and digital (T1/E1) VoIP gateway capabilities for packetized voice traffic.

In VoIP, the DSP segments the voice signal into frames, which are then coupled in groups of two and stored in voice packets. On the Cisco ICS 7750, these voice packets are transported by using IP in compliance with ITU-T specification H.323 and the Skinny Station Protocol. Because voice packets sent over an IP network are sensitive to delay, you need to have a well-engineered network end-to-end to successfully use VoIP.

Using the Cisco ICS 7750 with the PSTN

When connecting switched voice ports on the Cisco ICS 7750 directly to the Public Switched Telephone Network (PSTN), use the configuration described in this section so that you do not expose your network to telephone fraud.

PSTN to MRP Connectivity Using FXO Connections

The Cisco ICS 7750 can connect a user placing a call from the PSTN directly to your telephone network. You can configure the Cisco ICS 7750 as a phone switch that can switch a user to any location in that network, even to remote locations that are connected again to another PSTN. If your Cisco ICS 7750 has Foreign Exchange Office (FXO) ports (on an MRP) that connect the PSTN to analog lines in your telephone network, configure those FXO ports by using a private line auto ringdown (PLAR) connection, as follows:

Step
Command
Purpose

Step 1 

MRP(config)# voice-port 
slot/port

Enter voice-port configuration mode. The voice-port configuration commands are nested so that all subsequent commands affect only the specified voice port.

Step 2 

MRP(config-voiceport)# 
connection {plar | plar-opx} 
string

Configure the voice-port connection mode type (where string is the telephone number) by using the plar option, or if the connection is for a PLAR Off-Premises eXtension (OPX), use the plar-opx option. (Using the plar-opx option causes the FXO interface that you are configuring to not answer until the called side answers.)

IP Provisioning

The Cisco ICS 7750 is not currently designed to support IP provisioning of Cisco IP Phones across more than one subnet. The Cisco ICS 7750 is intended to be deployed in networks where the default gateway (typically an MRP), TFTP server (Cisco CallManager), and Cisco IP Phones are all located on the same subnet, to take advantage of the DHCP services that CNR provides for Cisco IP Phones.

Open Caveats in Release 2.4.0

This section describes open caveats in system software release 2.4.0, as follows:

Open Caveats in ICS System Manager in Release 2.4.0

Open Caveats in the Fault Management Module in Release 2.4.0


Note For caveats for Cisco IOS on ASIs and MRPs, refer to the Release Notes for the Cisco ICS 7750 for Cisco IOS Release 12.2(4)YH. For caveats for Cisco IOS on the SSP, refer to the
Release Notes for the Catalyst 2900 LRE XL Switches, Cisco IOS Release 12.0(5)WC5.


Open Caveats in ICS System Manager in Release 2.4.0

This section describes open caveats in ICS System Manager and related software components for release 2.4.0:

Software Installation and Upgrade Problems

Login Problems

Discovery Problems

Software Installation and Upgrade Problems

This section describes problems related to software installation and upgrade.

CSCdx53154

If you are installing release 2.4.0 with an attached CD-ROM drive, it is possible that after the SPE reboots, a message box might be displayed with a message similar to the following:

D:\ not accessible. 

or

Semaphore timeout.

Workaround—Restart the SPE. After the SPE restarts, the setup program will resume.

CSCdx06175

If you uninstall ICS System Manager, after rebooting the SPE, a message box will be displayed which says the following:

Cannot find the file C:\winnt\system32\cmd (or one of its components). Make sure the path 
and filename are correct and that ll required libraries are available.

This message box has no impact on system functionality.

Workaround—Close the message box. No further action is required.

Login Problems

This section describes a problem with ICS System Manager logins and passwords.

CSCdx68320

When you enter a User ID or password in the ICS System Manager Security page, characters other than alphanumeric characters (the uppercase and lowercase letters a through z, and the numbers
0 through 9) will be allowed. However, you cannot enter User IDs or passwords containing non-alphanumeric characters when logging in to ICS System Manager. If you attempt to log in to ICS System Manager with a User ID or password which contains a non-alphanumeric character, login will fail.

Workaround—Do not enter any non-alphanumeric characters when creating User IDs or passwords through the Security page in ICS System Manager.

Discovery Problems

This section describes a problem where ICSConfig does not properly discover the SSP.

CSCdx77824

It is possible that in rare situations ICS System Manager will report a duplicate IP address for the SSP. If this situation occurs, ICSConfig will generate the following error message:

Error Code: 102 
Cannot discover SSP. SSP <IP Address> is not reachable from SPE running
System Manager <IP Address, Subnet Mask>. 

Even if the duplicate IP address is resolved, ICSConfig might fail to recognize that the problem has been corrected and will continue to report a duplicate IP address for the SSP.

Workaround—Complete the following steps to restart the card discovery process:


Step 1 Access the SPE running System Manager. (Refer to the "Accessing the System" section in the "Operating the Cisco ICS 7750" chapter of the Cisco ICS 7750 Installation and Configuration Guide for instructions.)

Step 2 Enter the following commands:

net stop FMMServer
net start FMMServer

Step 3 Run ICSConfig. It should properly discover all cards in the chassis.


Open Caveats in the Fault Management Module in Release 2.4.0

This section describes open caveats in the Fault Management Module, as follows:

Software Installation Problems

SPE Problems

SAP Problems

CDP Problems

Software Installation Problems

This section describes a problem related to software installation.

CSCdv74876

After installing Cisco CallManager on an SPE, if the SPE is rebooted, it might not complete its boot sequence successfully.

You might be experiencing this problem if you are attempting to access the SPE through the SAP menu and it fails to give you access, or if Cisco IP Phones are not working properly (because the CallManager service might not have started on the SPE if it did not finish booting).

Workaround—To solve this problem, complete the following steps:


Step 1 Access the SPE Windows interface. (Refer to the "Accessing the System" section in the "Operating the Cisco ICS 7750" chapter of the Cisco ICS 7750 Installation and Configuration Guide for instructions.)

Step 2 Log in as an administrator (User ID administrator) and enter your password (the default is changeme).

Logging in should allow the MMC, STI1, and STI2 processes to complete. When these software configuration processes are complete, the SPE should be functioning normally.


SPE Problems

This section describes a problem related to SPEs.

CSCdv19549

After shutting down and rebooting an SPE, it is possible that the SPE might reboot a second time. It is also possible that after installing hot fixes, when the Setup program attempts to restart the SPE, the Setup program will not be able to resume successfully. In the latter case, if a monitor is connected, its display might change to a blue screen or the remote connection (such as Terminal Services Client) might time out.

This problem, though rare, can occur during initialization of a device driver. The second reboot of the SPE might take slightly longer than normal, because Microsoft SQL Server checks the integrity of its database tables due to the unexpected SPE reboot. The SPE should return to normal operation after the second reboot.

Workaround—If this problem occurred after hot fix installation, run the Setup program again after the SPE finishes its boot sequence.

SAP Problems

This section describes problems related to the SAP.

CSCdv90365

If you change the IOS login passwords of MRP, ASIs, or the SSP with ICSConfig, an error message similar to Failed to set alarm card password might be displayed.

Workaround—To solve this problem, complete the following steps:


Step 1 Open a Telnet session with the SPE.

Step 2 Enter the following commands:

net stop "Cisco Systems Console Server"
net stop FMMServer
net start "Cisco Systems Console Server"
net start FMMServer


CSCdv49147

If you are using the AC1_0_5 image on the SAP and you install an MRP in an empty chassis slot, the system might report zero degrees as the minimum and maximum operating temperature of the newly installed MRP, causing the SPE ALARM LED to turn on.

(The correct minimum and maximum operating temperature of the MRP is -55 and +125 degrees, respectively.)

Workaround—Reseat the SAP.

CSCds06164

If you move an SPE to a different chassis slot, if you establish a connection with the SAP, the menu might show the SPE in its original slot.

Workaround—Reboot the SAP.

CSCdu65741

Some events related to SAP functionality might not be logged, and LEDs on the SPE might stay on when they should turn off.

There is no workaround.

CDP Problems

This section describes problems related to the Cisco Discovery Protocol (CDP).

CSCdx12810

In rare situations it is possible that when you run ICSConfig, the SPE running System Manager might not be discovered. Even after trying the suggestions given in the corresponding error code, the problem will persist. Furthermore, if a new SPE or MRP is installed in the same chassis, the new card will not receive an IP address. If this error condition occurs, no log messages will be generated and the status of LEDs on the SPE will not change.

Workaround—Reboot the SPE running System Manager.

CSCdv81891

If ICSConfig assigns the same IP address to an SPE running Cisco Call Manager and another card, it might be because the necessary Cisco Discovery Protocol (CDP) driver is not running on the SPE, causing ICSconfig to generate an error message (error code 400).

The workaround provided with error code 400 is incorrect. Follow these steps to solve this problem:


Step 1 Connect a Monitor, Keyboard and Mouse to the SPE in the slot indicated by error message.

Step 2 On the SPE, choose Start > Settings > Control Panel > Administrative Tools > Event Viewer.

The Event Viewer window appears.

Step 3 In the left pane, click System Log.

Step 4 In the right pane, click Type.

This sorts the log messages by type.

Step 5 Scroll until Error log messages are visible in the Type column.

Step 6 Double-click the first Error message that you see that has tcpip in the Source column.

The Event Properties dialog for that error appears.

If the error is a duplicate IP address error, the error description will show something similar to the following:

The system detected an address conflict for IP address <IP Address> with the system having 
network hardware address <MAC Address>. Network operations on this system may be disrupted 
as a result.

The MAC address in the error description is the MAC address of the other device that is using the same IP address as the SPE.

Step 7 Locate the device with that MAC address and either change its IP address, temporarily disconnect that device from the network, or change the SPE IP address.

Step 8 Reboot the SPE.

Priority level 4 (P4)—You need information or assistance concerning Cisco product capabilities, product installation, or basic product configuration.

Priority level 3 (P3)—Your network performance is degraded. Network functionality is noticeably impaired, but most business operations continue.

Priority level 2 (P2)—Your production network is severely degraded, affecting significant aspects of business operations. No workaround is available.

Priority level 1 (P1)—Your production network is down, and a critical impact to business operations will occur if service is not restored quickly. No workaround is available.

Which Cisco TAC resource you choose is based on the priority of the problem and the conditions of service contracts, when applicable.

Cisco TAC Web Site

The Cisco TAC Web Site allows you to resolve P3 and P4 issues yourself, saving both cost and time. The site provides around-the-clock access to online tools, knowledge bases, and software. To access the Cisco TAC Web Site, go to the following URL:

http://www.cisco.com/tac

All customers, partners, and resellers who have a valid Cisco services contract have complete access to the technical support resources on the Cisco TAC Web Site. The Cisco TAC Web Site requires a Cisco.com login ID and password. If you have a valid service contract but do not have a login ID or password, go to the following URL to register:

http://www.cisco.com/register/

If you cannot resolve your technical issues by using the Cisco TAC Web Site, and you are a Cisco.com registered user, you can open a case online by using the TAC Case Open tool at the following URL:

http://www.cisco.com/tac/caseopen

If you have Internet access, it is recommended that you open P3 and P4 cases through the Cisco TAC Web Site.

Cisco TAC Escalation Center

The Cisco TAC Escalation Center addresses issues that are classified as priority level 1 or priority level 2; these classifications are assigned when severe network degradation significantly impacts business operations. When you contact the TAC Escalation Center with a P1 or P2 problem, a Cisco TAC engineer will automatically open a case.
