About the Rear Transition Module
The rear panel of the Cisco Unified Videoconferencing 3545 chassis contains four slots for the insertion
of Rear Transition Module (RTM) boards that connect to the chassis backplane. The RTM provides a
Circuit Switch Network connection.
Viewing System Indicators
You can view system-level monitoring information by monitoring the LED indicators on the front of the
Cisco Unified Videoconferencing 3545 chassis. The LEDs are connected to the chassis System
Information Card (SIC).
Note
You can also monitor chassis functions remotely via the web user interface of the MCU or gateway
installed in the top slot of the Cisco Unified Videoconferencing 3545 chassis. If you install a Cisco
Unified Videoconferencing 3545 EMP Enhanced Media Processor in the top slot of the Cisco Unified
Videoconferencing 3545 chassis, monitoring via the web is not available.
