a. Using a flat-blade screwdriver, loosen the two captive screws on the fan and
communications module.
b. Use the pull handle to slide the module out of the slot a few inches.
c. Grasp the sides of the module with both hands and remove it from the
DS4400 Storage Server.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling static-sensitive
devices, see “Handling static-sensitive devices” on page 41.
3. Unpack the new fan and communications module.
4. To install the new fan and communications module do the following:
a. Push the new fan and communications module all the way into its chassis
slot.
b. Use a flat-blade screwdriver to tighten the two captive screws on the new
module, securing it into place.
5. Check the fan and communications indicator light. See Figure 42 for the location
of the fan and communications indicator light.
v If the amber fault indicator light is on, make sure that the fan and
communications module is inserted all the way into the chassis and secured
in place.
v If the fault indicator light remains on, one or both fans inside the fan and
communications module might be malfunctioning. Replace the failed fan and
communications module with a spare, if available. Otherwise, shut down the
DS4400 Storage Server until you can replace the failed fan and
communications module with a new one.
6. Reconnect the interface cables that you disconnected in Step 1 on page 53 to
the new fan and communications module.
