b) Carefully slide the power supply unit all the way into the slot until it clicks into place.
c) Test the installation by trying to pull the power supply blank module out of the slot by the handle, without using the
release latch.
If the power supply blank module does not move out of place, it is secured in the slot. If the power supply blank
module moves, carefully press it all the way into the slot until it clicks in place.
Installing and Removing Fan Modules
This section provides instructions for installing and removing the fan modules for the Cisco MDS 9220i
switch.
If you are changing the airflow direction of all the modules in the chassis, you must shut down the switch
before replacing all the fan and power supply modules with modules using the other airflow direction. During
operations, all the modules must have the same direction of airflow.
Caution
Installing a Fan Module
To install a new fan module, follow these steps:
Before you begin
If a fan blank module is installed, remove it as follows:
• Grasp the fan module release latches with one hand and squeeze the release latch towards the each other.
• Holding the release latches, 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 red coloring (port-side intake airflow) or 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 slot until it clicks into place.
Step 3
Test the installation by trying to pull the fan module out of the slot without using the release latch.
If the fan module does not move out of place, it is secured in the slot. If the fan module moves, carefully press it all the
way into the slot until it clicks in place.
