About the Cisco Unified Videoconferencing 3545 System
The Cisco Unified Videoconferencing 3545 System is a high performance, multi-functional chassis that
supports mix-and-match functionality. This highly configurable and scalable design provides maximum
flexibility for configuring platforms to meet a wide variety of functional and performance application
requirements.
The Cisco Unified Videoconferencing 3545 System consists of a number of embedded applications on
blades that are inserted into the Cisco Unified Videoconferencing 3545 chassis.
About the Cisco Unified Videoconferencing 3545 Chassis
The Cisco Unified Videoconferencing 3545 chassis is 3.5" (2U) high and can mount in a 19-inch rack.
The chassis can accommodate a Cisco Cisco Unified Video conferencing 3545 module in each of its four
slots. Each board receives power via the backplane.
There are four slots at the front and rear of the chassis. The front slots are used for the main device
boards. The rear slots are used only by gateway Rear Transition Module (RTM) boards which allow a
connection to the ISDN or serial network.
The chassis provides easy access for maintenance and board replacement.

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.
System Power Indication
The POWER LED lights green to indicate that the power supply is operating normally. Red indicates
that one of the power supply units is malfunctioning.
System Alarm Indication
The ALARM LED lights green to indicate that the system is functioning normally. Red indicates that a
system failure has been detected.
System Fan Indication
The FAN LED lights green to indicate that the fans are operating properly. Red indicates a fan failure.
