System passwords
Due to the security enhancement in CSCud96071, it is impossible to log into the TC6.0 web interface
with blank credentials when an empty password was set in TC6.1.x and TC6.2.x. A workaround is to
execute the API command xCommand Systemunit AdminPassword Set Password: “”. Cisco does not
recommend using an empty password, and any system without password set will display a warning on
the screen. In a future TC software release, a system without password set will not be able to dial until
the password is set.
Extended BFCP port range
In TC6.2.0, UDP ports 5070 to 5077 are used for the BFCP connection when using SIP as dial
protocol. Prior to TC6.2, only port 5070 was used. If a firewall or access list is denying traffic on these
ports, it must be opened up to accommodate the new BFCP ports. The new ports are used because it
is a requirement for using ICE.
Hardware compatibility
Due to replacement of hardware components there are some constraints on running older software on
newly manufactured endpoints and Touch 8 devices. This is due to end of life of some components
and introduction of new components that require changes in the software. Executing the API
command “xStatus SystemUnit Hardware Module CompatibilityLevel” will reveal if there are any
constraints on the system. For a detailed list of compatibility levels and software constraints for the
Cisco TelePresence systems please see the appendices in this document:
Cisco TelePresence Systems hardware dependencies
Cisco TelePresence Touch 8 hardware dependencies
A lock prevents the system from downgrading to unsupported versions on endpoints as well as Touch
8 devices. If a downgrade attempt fails it may be due to lack of endpoint support or lack of Touch 8
support in the old software.
New hardware revision of the Cisco TelePresence Codec C40
February 2013, Cisco started shipping a new hardware revision of the C40 Codec, which is not
supported in older software versions except for TC4.2.4 and TC5.1.5 and later. C40s with serial
number F1AV05Fnnnnn (05 = week 5 F = 2013) or higher and FTT1705nn (17=2013 05=week 5) are
subject to this change. There are no changes in functionality between the new and the old revision.
