Replacing the Fan Tray
The following section provides the information needed to remove and replace the fan trays.
The fan trays are located on the right-hand side of the shelf’s front and on the right-hand side
of the rear. If you want to check or replace an air filter, you must remove the front fan tray first.
Removing the single operating fan tray leads to overheating very quickly. Ensure that one
operating fan tray is present in the system at all times.
Perform the following steps to replace the fan tray. These steps are the same for the front and
rear fan trays.
Step
Action
1.
Put on an ESD wrist strap.
Electrostatic discharge can damage circuits or shorten their life. Before touching the blade
or electronic components, ensure that you are working in an ESD-safe environment.
2.
Remove the replacement fan tray from the shipping box and ensure that it is the
correct model for the shelf and the required front or rear fan tray.
When a fan tray is taken out of operation or is removed during a replacement procedure, the
system manager compensates for the loss by increasing the speed of the remaining fans.
Running a fan on high speed for a long time can shorten the fan’s life and can exceed the
allowable acoustic noise limits. Replace the fan tray as soon as possible.
