The following issues currently apply to version TCU 4.2.1.
Reference ID
Summary
CSCug64002.
If the GUI operator and admin users are password protected, the passwords will
be corrupted when upgrading to TCU4.2.1 preventing user configuration access
n/a
If you upgrade from TCU 2.0 or earlier releases to TCU 4.0.0, you may experience
some failing diagnostics tests. Reboot the TCU again to resolve the problem.
n/a
When going from a point-to-point T3 call to a T3 multisite call using the Cisco
TelePresence Server (TS), the call will be disconnected and reconnected with the
added sites using the TS.
n/a
It is not possible to go from a call using the Cisco TelePresence Server (TS) to a
point-to-point call without the TS. To do this you will have to disconnect the
conference and redial without using the TS.
n/a
System name must be written with English characters or the name will become
invalid with a strange system name as the result.
n/a
If a T3 system is in a call with a concierge, it will become the master of the call if it
receives another T3 call. Normally the site making the call will become master,
unless they dial to another system that is already master.
n/a
No incoming call is possible if you are in a point-to-point T3 call with 1 briefer and
concierge.
n/a
If you calibrate the cameras during a call, the far end will get a black box in the
layout.
n/a
Even though NTP time sync is enabled, the TCU clock may drift (up to 2 minutes),
making logs and diagnostics timestamps somewhat imprecise.
n/a
We have observed an infrequent failure in the USB extender used between the
document camera and the TCU. If this happens you will not be able to control the
document camera or get any preview. Restarting the TCU with the USB extender
disconnected or reconnecting the USB connector to the TCU can rectify this
condition. Sometimes a power cycle of the document camera is needed to rectify
the problem.
n/a
If a power outage occurs the TCU file system could be affected. You will get a
warning in the diagnostic overview in Admin and a ticket to TMS if this happens.
Please run chkdsk on the TCU if files get corrupted.
n/a
The Digital Natural Audio Module (DNAM) diagnostics state will only be updated
after the codecs are booted.
n/a
When dialing out multiple calls (escalating to the TS) and none of the sites
answers the call, the conference will not be ended on the TS.
75816
DVI-I standards may cause presentation to fail given certain conditions.
82982
When upgrading from TMS the upgrade status shows 0% and the upgrade is
reported as failed when in fact the upgrade is successful.
73985
If an external keyboard or mouse is connected to the TCU a dialog may appear
asking to install drivers for a serial mouse. Click cancel to resolve this problem.
83376
The T3 system does not meet the Cisco password policy. It’s highly recommended
to set a password on the TCU and the C90 Codecs. See the Administrator Guide
for further information.
113990
Document camera using Linksys Ethernet adapter might not work after first boot. A
diagnostic test will indicate if this happens and a reboot of the TCU will fix the
issue.

Upgrading to TCU 4.2.1
Upgrading to TCU 4.2.1
CAUTION: You must back up your configuration before upgrading to TCU 4.2.1.
You must also remember the administrator user name and password for the backup
configuration. You will need these if you ever need to make use of this backup file.
CAUTION: If you are using Call Detail Records (CDR) for billing, auditing or any other
purpose, before you upgrade to this release, you must download and save your current
CDR data. If you downgrade from this release to any older version, the MCU might delete all
existing CDRs.
Prerequisites and software dependencies
TCU 4.2.1 requirements:

Cisco TelePresence Codec C90, running software version TC6.0. The TCU is only tested
with this software, so make sure this is loaded on all 3 Cisco TelePresence Codec C90s
shipped with the T3 system.

Cisco TelePresence Server running software version TS 2.3(1.55)

Cisco TelePresence Management Server 14.1.1

Touch buttons (SSTB) requires version 1.21 or later, but version 1.24 is recommended.
The new push button that comes with the new T3 Hardware is not connected to the TCU
and does not require a sw update.

Touch collaboration display (TCD) requires minimum version 1.10, but 1.24 is
recommended. Please refer to the Cisco TelePresence T3 Admin Guide on how to
upgrade the displays. The firmware of the displays is shown during TCU boot.

Main Video Displays (MVD) requires version 1.21 or later.
Please upgrade the Cisco TelePresence Server before upgrading the TCU.
Make sure you follow the steps carefully, especially if you upgrade remotely. If you fail to do so, you
may lose contact with the TCU and you will have to physically go to the room to finish the upgrade.
You will need to be familiar with “SSH” to do the upgrade. The password to access the TCU is “tec”
and you must log in as “administrator”.
Note: If you have the new T3 Hardware with 23” Touch collaboration displays with the new push
button and the DVI presentation switch version 3.0x or later, only SW version TCU4.0.0 or later is
supported.
Note: If you upgrade from TMS, you must still do the below steps manually BEFORE using TMS to
upgrade the system.
Note: An upgrade from < TCU 4.2 involves upgrading the Cisco TelePresence Codec C90 to TC5.1.
When upgrading from one main release to another, the codecs will require a new release key. Make
sure you have this key before you start the upgrade. Without this key TCU 4.2.0 will not work. TCU
4.2.0 also requires that all codecs have the correct product key (product type). Check that the system
has accepted the new release key and that it is listed with the correct product type by using SSH to
access the command shell and then issue the command ‘xStatus Systemunit’

Upgrading to TCU 4.2.1
Upgrade instructions
To upgrade to 4.2.1:
1.
Delete the ‘application.properties’ file from ‘e:/Tandberg/configuration’ if you upgrade from TCU
1.0.0
2.
The Installation Wizard will do all the other necessary changes to the configuration files.
3.
If you have problems starting the GUI, please delete the
“e:\tandberg\configuration\devices.properties” file. The installation wizard will then start after you
reboot the system.
4.
Follow the process outlined in the document Cisco TelePresence T1/T3 Administrator Guide
carefully. This document is available from Cisco upon request. Alternatively you can use TMS to
upgrade the system.
