210 QXS G2 Hardware Installation and Maintenance Guide
Installing a 5U84 RAID Controller or Expansion IOM
Comply with all ESD precautions. Refer to ESD Precautions on page 165 for additional information.
CAUTION: If passive copper cables are connected, the cable must not have a connection to a
common ground/earth point.
NOTE: When performing the following procedure, refer to Figure 175 .
1 Examine the controller or expansion IOM for damage, and closely inspect the interface connector.
Do not install if the pins are bent.
2 Grasp the controller or expansion IOM using both hands, and with the latch in the open position,
orient the module and align it for insertion into the target slot.
3 Ensuring that the controller or expansion IOM is level, slide it into the chassis as far as it will go.
A controller module that is only partially seated will prevent optimal performance of the RAID
chassis. Verify that the controller module is fully seated before continuing.
4 Set the module in position by manually closing the latch. See detail No.2, followed by No.1 in
Figure 173 on page 208.
You should hear a click as the latch handle engages and secures the controller or expansion IOM
to its connector on the back of the midplane.
5 Reconnect the cables.
6 See Verifying Component Operation on page 185.
NOTE: In a dual-controller system in which PFU is enabled, when you update the firmware on one
controller, the system automatically updates the partner controller.
Replacing a 5U84 Chassis
The RAID chassis or expansion chassis replacement procedure replaces a damaged 5U chassis CRU.
The procedure includes removing all CRU modules from a damaged chassis and installing them into a
replacement chassis.
IMPORTANT: The CRUs for the QXS-G2-484 systems using the 5U84 chassis are described in 5U84
Chassis CRU Replacement on page 190.
Whether your product is configured as a RAID chassis or an expansion chassis, a fully functional
replacement chassis requires the successful removal and installation of the following components:
•
All power and data cables
•
All DDICs from chassis drawers
•
Two power supply unit modules (both AC)
•
Five fan modules
•
Two controllers or expansion IOMs of the same model type
This procedure references the CRU component procedures described elsewhere in this chapter.
