The weight of this part or unit is more than 55 kg (121.2 lb). It takes specially trained persons, a
lifting device, or both to safely lift this part or unit. (C011)
CAUTION: To avoid personal injury, before lifting this unit, remove all appropriate subassemblies
per instructions to reduce the system weight. (C012)
Notes:
• Perform the following procedure only if directed to do so by IBM Remote Technical support or by a fix
procedure in the management GUI.
• An enclosure can have FRU P/N 01LJ112 or FRU P/N 01LJ607. When needed, an enclosure with FRU
P/N 01LJ607 is used to replace FRU P/N 01LJ112.
This task assumes that the following conditions are met:
• All power cables were removed from the enclosure, as described in “Powering off the 5U92 disk
enclosure” on page 44.
• All SAS cables were removed, as described in “Removing and installing a SAS cable” on page 40.
• The following FRUs were removed from the enclosure, as described in the applicable tasks:
– Top cover (“Removing the top cover” on page 21)
– Drives (“Removing a drive ” on page 82)
– PSU (1U) fascia (“Removing the fascia ” on page 91)
– Power supply units (“Removing a power supply ” on page 93)
– Secondary expander modules (“Removing a secondary expander module ” on page 84)
– Expansion canisters (“Removing an expansion canister ” on page 98)
– Fan modules (“Removing a fan module” on page 99)
• The expansion enclosure was removed from the rack, as described in “Removing a 5U92 disk enclosure
from a rack” on page 69.
• A suitably rated mechanical lift is available to support the weight of the enclosure.
About this task
The expansion enclosure contains the drive board, signal interconnect board, and internal power cables.
If a fault with the drive board or the intercanister link is suspected, you can replace the enclosure.
However, you can remove the parts from the old expansion enclosure and reinstall them in the
replacement enclosure.
Procedure
1. Remove the front display (4U) and PSU (1U) fascia from the old enclosure, as described in “Removing
the fascia ” on page 91.
a) Install the front display (4U) and PSU (1U) fascia on the new enclosure, as described in “Installing
or replacing the fascia” on page 24.
2. Remove the display panel assembly from the old enclosure, as described in “Removing the display
panel assembly ” on page 95.
a) Install the display panel assembly into on the new enclosure, as described in “Installing or
replacing the display panel assembly ” on page 60.
3. Remove the fan interface boards from the old enclosure, as described in “Removing a fan interface
board ” on page 101.
a) Install the fan interface boards into on the new enclosure, as described in “Installing or replacing
a fan interface board ” on page 64.
