Module Remove and Replace 213
Ta b l e 46 Notes:
1
If you temporarily stack the drives before installing them, insert static dissipative foam between the
drive modules.
2
Fully configured 5U84 chassis can weigh up to 128 kg (282 lb) and require a suitable mechanical lift.
3
Within the replacement chassis, each controller or expansion IOM must be reinstalled into the same
controller or expansion IOM slot from which it was extracted from the damaged chassis (0A > 0A and
0B > 0B, respectively). For FC/iSCSI controllers, the SFPs installed in the CNC ports need not be
removed. For SFP replacement, see SFP Option for CNC Ports on page 231.
4
Within the replacement chassis, reinstall each drive or drive blank into the same drive slot from
which it was removed from the damaged chassis. To ensure optimal cooling throughout the chassis,
dummy drive carriers must be fitted to all unused drive slots.
Removing a Damaged 5U84 Chassis from the Rack
This section provides a procedure for removing a damaged 5U chassis from its rack location.
CAUTION: It is recommended that all DDICs be removed from the drawers before removing the
chassis from the rack. A suitable mechanical lift is required to move a high-density 5U84 chassis.
1 Disconnect the power cables and data cables between devices as needed:
a Between the cascaded chassis.
b Between the controller and peripheral SAN devices.
c Between the controller and the host.
NOTE: Label the cables to facilitate reconnection of the storage devices.
2 Position a suitable mechanical lift to receive the chassis.
3 Remove the retaining screws that secure the front and rear of the chassis to the rack and rails.
NOTE: Do not remove the ear components from the failed chassis: integrated ear
components and covers are provided with the replacement chassis CRU.
4 Maintaining a level position, carefully slide the chassis from the rack.
8 Facing the front of the 5U chassis, access the
drawers and install DDICs retrieved from the
damaged chassis into the replacement chassis.
