Replacing Fans (Hot-Swap)
To Remove Cooling Fans:
1. Check the LEDs on the back of the expansion unit.
2. Slide the latch left or right to unlock the fan.
3. Use the handle (black knob) to pull the fan from the
expansion unit.
4. Install the new fan by inserting it into the expansion
slot and making sure it is seated into the mid plane
connector. Slide the latch into the middle position.
5. Check the LEDs. If the fault LEDs do not turn off
after a few seconds, refer to “Symptom-to-FRU Index”
on page 7.
Note
The Fan units are hot swap redundant; however, when
one fan fails, the failing fan unit needs to be replaced
within 48 hours in order to maintain redundancy and
optimum cooling. When replacing the failed fan unit,
insure that this replacement is performed in less than
10 minutes to prevent any overheating. If it takes
longer than 10 minutes to replace the fan unit, you
must shut down the expansion unit to keep the unit
from overheating.
For information on expansion unit shutdown, see
“Performing a Shutdown” on page 4.
