Table 46 Notes:
1
If you temporarily stack the drives before installing them, insert static dissipative foam between the
drive modules.
2
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.
3
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,
drive blanks must be fitted to all unused drive slots.
Removing a Damaged 2U Chassis from the Rack
This section provides a procedure for removing a damaged chassis from its rack location.
CAUTION:
It is recommended that all drive modules be removed before removing the chassis. Two
people are required to move the 2U 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 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.
3 Maintaining a level position, carefully slide the chassis from the rack.
4 Place the chassis on a static-protected work surface near the replacement chassis, with the
removed drive modules and screws.
Installing the Replacement 2U Chassis in the Rack
CAUTION: If any licenses other an Q-Tier (virtualization) were installed on the system, after chassis
swap, customer must obtain a new license set tied to the new OEM serial number. Refer to the QXS
G2 Licensing Guide to obtain the license set. Also, differentiate the TLA serial number from the OEM
serial number.
This section provides a procedure for installing the replacement chassis in its rack location.
IMPORTANT: Refer to Installing 2U Chassis on page 62 when installing the chassis into the rack.
