Cisco Unified Videoconferencing 3545 System Chassis Overview

System Temperature Indication

The TEMP LED lights green to indicate that the temperature inside the chassis is within the acceptable

range. Red indicates overheating when the temperature reaches and/or passes the upper threshold.

Flashing green and red indicates that the temperature is close to the upper threshold. If the temperature

falls below the lower threshold, the LED remains green. The LED flashes green to indicate a sensor

malfunction. The upper and lower threshold levels are configurable in the web user interface of the MCU

and gateway.

Normal System Startup LED Indications

This section describes the normal LED indications that you should see when the system starts up.

At startup, the normal system monitor LED indications are as follows:

•

Cisco Unified Videoconferencing 3545 Chassis Power Supply

The rear panel of the Cisco Unified Videoconferencing 3545 chassis contains dual power supply units,

each with a power switch, an AC mains power connector and a safety fuse. The two PSUs use current

sharing to provide redundancy—if one PSU fails, the second PSU can handle the operational load of the

chassis until the failed unit is replaced. The PSUs are located to the left of the chassis rear panel., as

shown in .

Each power supply has one LED indicator—green to indicate normal operation, red to indicate a

malfunction.

In normal operation, both PSUs display a lit green LED, and the front panel system monitoring POWER

LED lights green.

Note

To enable PSU redundancy, connect both power inlets to a power source. If you connect only one power

cable, the POWER LED on the chassis front panel and the LED indicator on the PSU not in use will both

light red.

The POWER LED indicator lights green and remains green.

The ALARM, FAN and TEMP LED indicators flash twice, alternating between red and green. When

the platform initialization is complete, the LED indicators remain green.
