Introduction
Due to replacement of hardware components there are some constraints running older software on
newly manufactured endpoints. This is due to end-of-life of some components and introduction of new
components that require support in the software. There are two ways to identify the minimum software
version of a system, using the xAPI/tshell or by looking at the TAN number. These methods are
presented in the following. Downgrading to an unsupported software version will fail. The latest
software releases are always backward compatible with all hardware versions.
NAND Flash
The Cisco TelePresence endpoints are using a NAND flash memory for general storage and transfer
of data. The endpoints running TC software will be manufactured with a newer version of the flash
memory. For simplicity in this document we will call the first flash version 0 and the second flash
version and the third version (expected Summer 2014) version 2. Endpoints that have version 1 of the
flash memory must run software TC3.1.5 and later, 4.2.0 and later or 5.0.0 and later. Endpoints that
have version 2 of the flash memory must run software TC5.1.9 and later, TC6.1.2 and later or TC7
and later.
If your endpoint does not have the CompatibilityLevel command or it returns compatibility level 0 it has
the flash version 0 installed. This means that any software version can be installed on the system.
When the compatibility level is higher than 0, a newer software release is needed. Version 2 of the
flash memory will be identified by software compatibility level 4. Please refer to the compatibility
level table for further details.
Integrated camera
For units with an integrated camera (EX60/EX90 and MX200/MX300) the camera software is
embedded into the application software. Units shipped with the E4 sensor cannot be downgraded or
upgraded to any software version lower than TC4.2.4 or TC5.1.1 unless support is specifically
documented in the release notes for the software you are downgrading to. Although 5.1.1 can be
installed, Cisco recommends TC5.1.6 due to major color calibration improvements for MX series with
the E4 sensor. CSCud31649.
To check which camera sensor the EX series or MX series product has, execute the API command
“xStatus camera HardwareID”.
