Step 1
Ensure that the system (earth) ground connection has been made.
Step 2
Make sure the power cord is disconnected before installing the power supply.
Step 3
Verify that the power switch is in the off (0) position on the power supply that you are installing.
Step 4
Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.
Step 5
Tighten the power supply captive screw.
Step 6
Plug the power cord into the power supply.
Step 7
Connect the other end of the power cord to an AC input power source.
Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power
cord to connect the Cisco MDS 9396S switch to your outlet receptacle. See the
section.
Note
Step 8
Turn the power switch to the on (|) position on the power supply.
Step 9
Verify power supply operation by checking that the power supply (P/S) LED in the front panel is green. If the LED is
not green, see the
Cisco MDS 9000 Family Troubleshooting Guide
.
Removing and Installing Fan Modules
This section provides instructions for removing and installing the fan modules for the Cisco MDS 9396S
switch.
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.
The Cisco MDS 9000 Family has internal temperature sensors that can shut down the system if the temperature
at different points 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.
Caution
While removing the fan module, keep your hands and fingers away from the spinning fan blades. Let
the fan blades completely stop before you remove the fan module.
Statement 258
Note
To remove the existing fan module, follow these steps:
Step 1
Locate the fan module in the back of the switch.
Step 2
Loosen the fan module captive screw.
Step 3
Slide the seating tabs toward the center of the fan module.
Step 4
Grasp the fan module handle and pull it outward.
