Maintain Fan Modules - Dell EqualLogic PS Series Hardware Owner's Manual

5 Maintain Fan Modules

The PS6610 array contains five cooling fan modules.
The array is capable of operating with one failed fan module; however all five cooling modules are
required to maintain long-term cooling and reliability of the array.
Remove a Cooling Fan Module
Although an array can operate with only four working fan modules, you should replace the failed fan
unit as soon as possible. For proper array cooling, do not remove the failed fan unit until you are
ready to replace it.
Caution: The fan module replacement procedure (removal and installation) should be completed in
less than 2 minutes to ensure proper cooling of the array.
How to Remove a Cooling Fan Module
Wear electrostatic protection when handling a cooling module. See Hardware Protection on page 6.
To remove a cooling module:
1. From the rear of the unit, hold the handle protruding from the cooling fan and push down on the
orange release latch to the right (callout 2 in Figure 26) with your thumb.
2. Pull the module from the slot, as shown in Figure 26, until it is clear of the chassis.
