Chapter 4 Troubleshooting the Installation

Troubleshooting the Cooling Subsystem

Troubleshooting the Cooling Subsystem

You may need to troubleshoot the cooling subsystem if an overtemperature
condition occurs. The cooling subsystem of the router consists of a blower module
in the chassis and a fan in each of the power supplies. The blower module and the
power supply fans circulate air to maintain acceptable operating temperatures
within the router (

Figure 4-11

).

This section contains information to troubleshooting the cooling subsystem and
includes:
