Replacing a Rear (Internal) Drive-Bay Module
The optional, rear drive-bay module provides eight drive bays.
Note
When the rear drive-bay module is used, PCIe slot 12 is not available because there is not enough clearance.
Note
When the rear drive-bay module is populated with SAS/SATA drives, the air diffuser must be installed.
Step 1
Shut down and remove power from the server as described in
page
35.
Step 2
Slide the server out the front of the rack far enough so that you can remove the top cover. You might have to detach
cables from the rear panel to provide clearance.
Caution
If you cannot safely view and access the component, remove the server from the rack.
Step 3
Remove the top cover from the server as described in
Step 4
Remove any existing rear drive-bay module:
a) Remove any drives from the existing rear drive-bay module and set them aside.
b) If the air diffuser is present on the module, remove the diffuser. Lift straight up on the diffuser and set it aside.
It is not necessary to remove the rear supercap unit from the diffuser.
c) Disconnect any cable from a RAID controller or NVMe switch card from the module connectors.
d) Loosen the two screws that secure the module to the chassis.
e) Grasp the module at each end and lift up evenly to disengage its connector from the socket on the motherboard.
Step 5
Install a new rear drive-bay module:
a) While holding the new module level, align it over the socket on the motherboard and the two screw-holes.
b) Gently press the module connector to the motherboard socket. Stop when the module frame sits flat over the
screw-holes.
c) Install the two screws that secure the module to the chassis.
d) Connect any cable from a RAID card or NVMe switch card to the new module backplane.
e) Reinstall the air diffuser to the module if you removed one earlier (required only if the module is populated with
SAS/SATA drives).
In a system with only one CPU module, an additional filler panel is required in PCIe slot 11 to ensure
Note
adequate air flow. See
f) Install your drives to the bays in the new module.
