Cisco 7600 Internet Router Components

Component Hot Swapping

You can hot swap all modules (including the supervisor engine if you have a redundant supervisor engine) and fans. You can add, replace, or remove modules without interrupting the system power or causing other software or interfaces to shut down.

Note Although the FlexWAN module supports hot swapping, individual port adapters do not. To replace port adapters, you must first remove the FlexWAN module from the chassis and then install or replace port adapters as required.

This section describes the major hardware components for the Cisco 7609

Internet Router.

Fan Assembly

The system fan assembly provides cooling air for the supervisor engine and the switching modules. The fan assembly is located in the chassis. Figure 1-2shows the direction of airflow into and out of the Cisco 7609 Internet Router. Sensors on the supervisor engine monitor the internal air temperatures. If the air temperature exceeds a preset threshold, the environmental monitor displays warning messages.

If an individual fan within the assembly fails, the FAN STATUS LED turns red. To replace a fan assembly, see the “Removing and Replacing the Fan Assembly” section on page 5-12.

Note Refer to the Cisco 7600 Series Internet Router Software Configuration Guide for information on environmental monitoring.
