Chapter 2 Installing the Cisco MDS 9100 Series

Removing and Installing Components

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.

Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco MDS 9100 Series Switch to your outlet receptacle. See the “Jumper Power Cord” section on page C-5.

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 9140 Switch and the Cisco MDS 9120 Switch. The Cisco MDS 9124 Switch does not have field-replaceable fan modules.

Removing a Fan Module on the Cisco MDS 9140 Switch, the Cisco MDS 9120 Switch, and the Cisco MDS 9134 Switch

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 Family has internal temperature sensors that are capable of shutting down the

 

 

 

 

 

system if the temperature at different points within the chassis exceed certain safety thresholds. To be

 

 

 

 

 

effective, the temperature sensors require the presence of airflow; therefore, in the event a fan module is

 

 

 

 

 

removed from the chassis, the Cisco MDS 9000 Family will be shut down after five minutes to prevent

 

 

 

 

 

potentially undetectable overheating. However, the switches will shut down sooner if the higher-level

 

 

 

 

 

temperature threshold is exceeded.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Warning

When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the

 

 

 

 

 

fan blades completely stop before you remove the fan tray. Statement 258

 

 

 

 

 

 

 

 

 

 

 

To remove the existing fan module, follow these steps:

 

 

 

 

 

 

 

 

Step 1

Locate the fan module in the back of the switch.

 

 

 

Step 2

Slide the seating tabs toward the center of the fan module.

 

 

 

Step 3

Grasp the fan module handle and pull it outward.
