Overview

The Cisco uBR10012 chassis uses a fan assembly module containing fans to supply cooling air to the
chassis. The fan assembly connects to the chassis through a blind mate connector that plugs into the
cable assembly and then into the chassis backplane. The fan assembly modules are identified by their
product part numbers. The fan assembly modules supported on the Cisco uBR10012 chassis are:

• Fan Assembly Module (UBR10-FAN-ASSY=)

• Fan Assembly Module (UBR10012-FAN-PLUS=)

Fan Assembly Module (UBR10-FAN-ASSY=)

This fan assembly module as shown in Figure 1 has four internal fans that draw cooling air into the front
of the chassis and directs it across the internal components. The air is exhausted through the openings at
the rear of the chassis. The fan assembly module works at two speeds:

• Low speed (with a clean air filter)

• High speed (with a clean air filter)

The temperature of the fan module at the module air outlet determines the operating speed. Three LEDs
indicate the status of the fan assembly.

Table 1 lists the LEDs on the fan assembly module.

Table 1 Fan Assembly LEDs and Their Function

LED Status Description

FAN OK

Green This indicates that system is functioning normally; all fans are

operating.

SINGLE FAN FAIL

Yellow This indicates that one of the fans in the fan module has failed.

The fan module can still provide enough cooling to safely
operate the Cisco uBR10012 router chassis, but it might begin
operating the fans in its high-speed mode to do so. Replace the
fan assembly module as soon as possible.

MULTI FAN FAIL

Yellow This indicates that two or more fans in the module have failed,

and that the module is no longer able to consistently cool the
Cisco uBR10012 router chassis. To prevent overheating of the
chassis and possible damage to the line cards and other
modules, replace the fan assembly module immediately.

Four alarms (System OK, FAN-MISSING, PARTIAL-FAN Failure, and TOTAL-FAN Failure) are used
for monitoring the fan module.

Fan Assembly Module (UBR10012-FAN-PLUS=)

This fan assembly as shown in Figure 2 has nine internal fans that draw cooling air into the front of the
chassis and directs it across the internal components. This fan assembly module provides:

• Increased cooling capability

• Higher redundancy in case of a failure

• Repositioned thermal sensor that detects the ambient temperature of the cable plant or facility and

adjusts the variable fan speeds to maintain the temperature

1 Fan assembly module —

This fan assembly module works at four variable speed levels (0, 1, 2, and 3). The operating speed of the
fan is determined by the temperature of the facility. A thermistor, mounted on the fan assembly module,
is placed in front of the vent holes on the front panel. It measures the ambient air temperature on the
outside of the fan module. The threshold temperatures and speed levels are set internally and the fan
assembly controller monitors the thermistor and controls the speed of the fan. When powered on, the
fans operate at a speed according to the ambient average air temperature of the facility at the appropriate
speed level.

Note On startup, it may take up to 30 seconds for the fans to stabilize at the appropriate speed.

Three LEDs indicate the status of the fan assembly. Table 1 lists the LEDs on the front panel of the fan
assembly module. In addition, there is a PRODUCT ID LED/switch on the front panel of the fan
assembly module (see Figure 3).

Activated

If the PRODUCT ID LED/switch is illuminated (green), the Cisco IOS software identifies the fan
assembly module as UBR10012-FAN-PLUS only if you are running a supported Cisco IOS release on
the chassis. Otherwise, the software reports the default UBR10-FAN-ASSY product part number and a
FAN-MISSING alarm may be randomly raised. To clear the alarm, see “Troubleshooting the Fan

Assembly” section on page 23.

Tip Use a small object, such as a paper clip, to press the PRODUCT ID LED/switch inside the cavity on the

front panel of the fan assembly module.
