4.7 Replacing Fan Trays
The following section describes the procedure for the replacement of 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.
System Damage
Insufficient cooling may damage the system.
The cooling system is designed to provide sufficient cooling with a single fan tray at work.
However, under bad conditions or due to a failure of the remaining fans, the cooling
capacity of a single fan tray may not suffice.
Avoid delays during fan replacement.
Fan Damage
When a fan tray is taken out of operation or is removed during a replacement procedure, the
system manager will compensate for the loss by increasing the speed of the remaining fans.
Turning on high speed for a long time may shorten the life of the fans and may exceed
allowable acoustic noise limits.
Replace the fan tray without delays.
System Damage
Removing the single operating fan tray will lead to overheating very quickly.
Make sure that there is always one operating fan tray present in the system.
Damage of Circuits
Electrostatic discharge and incorrect installation and removal of the product can damage
circuits or shorten their life.
Before touching the product make sure that your are working in an ESD-safe environment
or wear an ESD wrist strap or ESD shoes. Hold the product by its edges and do not touch any
components or circuits.
