Feature Overview
The Cisco uBR10012 universal broadband router uses a fan assembly module (Figure 1 on page 3)
containing four fans to supply cooling air to the chassis.
The fan assembly is located at the top of the chassis and is connected to the chassis with a blind mate
connector that plugs into a cable assembly and then into the chassis backplane.
Four internal fans draw cooling air into the front of the chassis and direct it across the internal
components to maintain an acceptable operating temperature. The air is exhausted through openings in
the rear of the chassis.
The fan assembly module works at variable speeds:
• Low speed (with a clean air filter): approximately 280 cubic feet per minute (cmf)
• High speed (with a clean air filter): approximately 450 cmf
The operating speed is determined by the fan assembly module. If the temperature at the fan’s outlet gets
to 40°C, then the blower starts to increase the speed of the fans. It does not reach high speed, however,
until the temperature at the outlet reaches 50°C.
Three LEDs (System OK, Single Fan Failure, and Multi-Fan Failure) located on the front of the fan
assembly indicate the status of the fans (see Table 1 on page 3).
Figure 1 on page 3 shows the fan assembly module.

Table 1 Fan Assembly LEDs and Their Function
LED Status Description
System OK Green System is functioning normally; all fans are operating.
Single Fan Failure Yellow A single fan has failed; system triggers alarms, but the fan assembly
is still able to properly cool the chassis. Repair or replace the fan
assembly immediately.
Multi-Fan Failure Yellow Two or more fans have failed, and if the operating temperature
inside the chassis rises too high, the system automatically shuts
down. Repair or replace the fan assembly immediately.
