Introduction

Introduction

These release notes describe new features, requirements, restrictions, and caveats for both Unified Communications Manager and IM and Presence Service. These release notes are updated for every maintenance release but not for patches or hot fixes.

Unified Communications Manager, the call-processing component of the Cisco Unified Communications System, extends enterprise telephony features and capabilities to IP phones, media processing devices, voice-over-IP (VoIP) gateways, mobile devices, and multimedia applications.

The IM and Presence Service collects information about user availability, such as whether users are using communications devices (for example, a phone) at a particular time. IM and Presence Service can also collect information about individual user communication capabilities, such as whether web collaboration or video conferencing is enabled. Applications such as Cisco Jabber and Unified Communications Manager use this information to improve productivity amongst employees, that is, to help employees connect with colleagues more efficiently and determine the most effective way for collaborative communication.


Note


In the past, export licenses, government regulations, and import restrictions have limited Cisco System's ability to supply Unified Communications Manager and IM and Presence Service worldwide. Cisco has obtained an unrestricted US export classification to address this issue.

Be aware that after you install an unrestricted release, you can never upgrade to a restricted version. You are not even allowed to fresh install a restricted version on a system that contains an unrestricted version.


Before you install or upgrade either product, Cisco recommends that you review the Related Documentation for information about the documentation available.

Hardware server requirements

Server support for Cisco Unified Communications Manager

The following sections describe the system requirements for this release of Cisco Unified Communications Manager and IM and Presence.

Make sure that you install and configure Unified CM and IM and Presence on a Cisco Media Convergence Server (MCS), a Cisco Unified Computing System (UCS) server, a Cisco-approved HP server configuration, or a Cisco-approved IBM server configuration. For information about which MCS and UCS servers are compatible with this release of Unified CM or IM and Presence, see the related compatibility matrix.

Server support for the IM and Presence Service


Note


The IM and Presence Service requires 4 GB of RAM, except for the 500 user and Business Edition 6000 OVA deployments, which require 2 GB of RAM.


The IM and Presence service is software that is loaded onto a hardware server. The hardware server must meet the following requirements:

  • One of the following server models:

  • DVD-ROM drive

  • Keyboard, mouse, and monitor


Note


Additional server requirements, such as port and IP address requirements, are described in the Cisco Unified Communications Manager TCP and UDP Port Usage Guide, Release 9.0(1) here: http:/​/​www.cisco.com/​en/​US/​docs/​voice_ip_comm/​cucm/​port/​9_0_1/​CUCM_​BK_​T98E8963_​00_​ .


The IM and Presence installer checks for the presence of the DVD-ROM drive, sufficient hard drive and memory sizes, and sufficient CPU type and speed.

IM and Presence supports bridged upgrades from any of the following servers:

  • MCS-7825-H2-IPC1

  • MCS-7825-H2-IPC2

  • MCS-7835-H1-IPC1

  • MCS-7835-I1-IPC1

  • MCS-7845-H1-IPC1

  • MCS-7845-H2-IPC1 (only if each of the two disks has less than 72GB of storage space, otherwise it is fully supported)

  • MCS-7845-I1-IPC1

The bridged upgrade allows you to create a DRS backup on the discontinued hardware. You can then restore the DRS backup on supported hardware after you complete a fresh IM and Presence installation on the supported hardware. If you attempt an upgrade on discontinued hardware, a warning displays on the interface on the interface and on the CLI, informing you that Unified CM or IM and Presence only supports the functionality to create a DRS backup on this server.

Uninterruptible power source

Cisco recommends that you connect each Unified CM or IM and Presence server to an uninterruptible power supply (UPS) to provide backup power and protect your system against a power failure.


Caution


When the MCS-781x and MCS-782x servers are not connected to a UPS, they run a higher risk of file corruption during power outages because the cached data is lost during a power outage on these servers with drive write cache enabled (and no battery backup). To prevent file system corruption, you must connect these servers to a UPS.


When Unified CM and IM and Presence run on one of the servers listed in the table below, basic integration to the UPS model APC SmartUPS 1500VA USB and APC 750VA XL USB is supported.

Integration occurs via a single point-to-point USB connection. Serial and SNMP connectivity to UPS is not supported, and the USB connection must be point-to-point (in other words, no USB hubs). Single- and dual-USB UPS models get supported with the APC SmartUPS 1500VA USB and APC 750VA XL USB. The feature activates automatically during bootup if a connected UPS is detected.

Alternatively, you can execute the CLI command show ups status to show the current status of the USB-connected APC smart-UPS device and starts the monitoring service if it is not already started. The CLI command also displays detected hardware, detected versions, current power draw, remaining battery runtime, and other relevant status information.

When the feature is activated, graceful shutdown will commence as soon as the low battery threshold is reached. Resumption or fluctuation of power will not interrupt or abort the shutdown, and administrators cannot stop the shutdown after the feature is activated.

For unsupported Unified CM or IM and Presence releases, MCS models or UPS models, you can cause an external scripts to monitor the UPS. When low battery is detected, you can log in to the Unified CM or IM and Presence server by using Secure Shell (SSH), access the CLI, and execute the utils system shutdown command.


Note


If your pre-9.0 Unified CM or IM and Presence Service runs on a deprecated server, you can upgrade it by using the Bridge upgrade procedure.
