Upgrading to 4.0(2.8)
Prerequisites and software dependencies
Software dependencies
In the case of the TelePresence Server MSE 8710 blade(s), the Cisco TelePresence Supervisor MSE 8050
blade must be running Supervisor software version 2.2 or later.
Prerequisites
The software upgrade process requires a hardware restart. Schedule a downtime window and notify users of
when the service will be unavailable. The duration of an upgrade can be up to 25 minutes. Have the following
available and complete the backup processes described before you proceed to upgrade the software:
n New software package.
l For hardware platforms, this will be a file with a .zip extension, for example cisco_ts_media_300_4.0_
2.8.zip for the Media 310/320 platforms. You must unzip this file before you can use it.
l For the virtual machine platform, the initial install file file has a .ova extension but the upgrade package
has a .tgz extension, for example, Cisco_tsVirtualMachine_4.0_2.8.ova and Cisco_
tsVirtualMachine_4.0_2.8.tgz. You do not need to unzip either of those packages before you use them.
n Current software image file (in case you need to reverse the upgrade).
n Backup of the configuration (the configuration.xml file).
n You will require the administrator user name and password for the configuration backup file if you ever need
to use the backup. If you attempt to downgrade / restore the software and you cannot load an appropriate
configuration file, you may be unable to log in to the device.
n If using Call Detail Records (CDRs), or any other logs, for billing, auditing or other purposes, you must
download and save your logged data. When the device reboots as part of the upgrade, all existing CDRs
will be deleted.
n Administrative access to all units to be upgraded.
n The model numbers and serial numbers of your devices in case you need to contact Cisco Technical
Support.
CAUTION: Make sure that all the backup processes described in this section have been completed before
you start the upgrade. Failure to do so could result in data loss.
CAUTION: If you are upgrading a cluster you must upgrade all blades in the cluster to the same software
version.
Note: While you are upgrading a cluster, or restarting it for another reason, the master cannot report the
cluster's full capacity until the slaves have also restarted. Any devices that poll the master for such
information should check that the slaves are back up before assuming that the capacity has permanently
been reduced, or that there is some other fault in the cluster.
