IBM J15, Manual

Page: 104 / 142

When the enclosure is not secured to the rails in a rack, you can minimize the risk of injury and make
maneuvering the enclosure on a lift easier. However, even after you remove the drives, power supply
units, secondary expander modules, canisters, fans, and cover, the enclosure weighs 43 kg (95 lbs).
Procedure
Sliding the expansion enclosure out of the rack
Note: You can accomplish most service actions when the expansion enclosure is fully extended from the
rack on its slide rails.
1. Loosen the locking thumb screws ( 1 ) on the front of the enclosure, as shown in Figure 71 on page
76.

2. Remove the fascia that covers the control enclosure and the other two components of the building
block.
3. Carefully slide the enclosure forward out of the rack ( 2 ), as shown in Figure 71 on page 76.
4. Locate the left and right blue release tabs near the front of the enclosure. Pull both release tabs
forward to unlock the drawer mechanism ( 3 in Figure 71 on page 76).
5. Slide the enclosure and inner rail member out of the rack ( 4 in Figure 71 on page 76).
For safety, ensure that a mechanical lift or other mechanism is available to support the weight of the
enclosure.
Removing the expansion enclosure from the rack
Note: Continue the procedure (step “6” on page 76 through step “8” on page 76) only if you must
completely remove the expansion enclosure from the rack to complete a service procedure.
6. Power down the expansion enclosure and disconnect all power cords.
7. Remove all of the following parts from the enclosure, as described in the following procedures:
• “Removing the top cover” on page 21
• “Removing the fascia ” on page 91 (for the PSU fascia) and “Removing a power supply ” on page
93
• “Removing a drive ” on page 82
• “Removing a secondary expander module ” on page 84
• “Removing an expansion canister ” on page 98 and “Removing and installing a SAS cable” on page
