Fan CRUs
The two fan CRUs are hot-swappable and redundant.
Fault LEDs
These amber LEDs light when a fan failure occurs.
Latches and handles
Use the latches and handles to remove or install the fan CRUs.
Attention: Do not run the storage server without adequate ventilation and cooling,
because it might cause damage to the internal components and circuitry.
Both fan units must always be in place, even if one is not functioning properly, to
maintain proper cooling.
Use the following procedure to replace a hot-swap fan:
1. Check the LEDs on the back of the storage server.
2. If the amber Fault LED is on, remove the fan CRU that has failed.
a. Slide the latch to unlock the fan CRU.
b. Use the handle (black knob) to pull the fan from the storage server. See
Figure 44.
3. Install the new fan unit.
a. Place the fan CRU in front of the fan slot.
