Installing a Cisco MDS 9132T Switch

Before you begin

If a fan blank module is installed, remove it as follows:

• Press the two sides of the fan blank module handle and pull on the handles enough to unseat it from its

connectors.

• Holding the handle, pull the module out of the chassis.

• A fan slot must be open and ready for the new fan module to be installed.

• You must have a new fan module on hand and ready to install within one minute of removing the original

fan module if the switch is operating.

• The new fan module must have the same airflow direction as the other fan and power supply modules

installed in the switch. All of these modules must have either red coloring (port-side intake airflow) or

they must all have blue coloring (port-side exhaust airflow).

Step 1

Holding the fan module by its handle, align the back of the fan module (the side with the electrical connectors) to the

open fan slot in the chassis.

Step 2

Slide the fan module into the fan module bay until it clicks into place and tighten the locking screw.

Step 3

Verify that the Status LED turns on and becomes green.

Removing a Fan Module

The fan module is designed to be removed and replaced while the system is operating without presenting an

electrical hazard or damaging the system.

Caution

The Cisco MDS 9000 Series Switches have internal temperature sensors that can shut down the system if the

temperature within the chassis exceed certain safety thresholds. To accurately monitor the system temperature,

the temperature sensors require sufficient airflow through the chassis. In the event that a fan module is removed

from the chassis and the airflow is reduced, the system will bypass the temperature sensor information and

shut down after five minutes to prevent undetected overheating. However, the switches will shut down sooner

if the major temperature threshold is exceeded.
