Module Remove and Replace 183
The blue OK to Remove LED (back of chassis) illuminates to indicate that the controller module can
be safely removed.
4 Illuminate the white Identify LED of the chassis that contains the controller module to remove by
running the command:
set led enclosure 0 on
The Display LED on the Ops panel located on the chassis left ear will be blinking green when the
above command is invoked.
NOTE: See the QXS G2 CLI Reference Guide for additional information.
Removing a 2U RAID Controller or an Expansion IOM
IMPORTANT: Considerations for removing controller modules:
• In a dual-controller environment, you may hot-swap a single controller module in an operational
chassis, provided you first shut down the faulty controller using the disk management utility (GUI)
or the CLI.
• In a dual-controller environment—if replacing both controller modules—you must adhere to the
instructions provided in Before You Begin on page 180.
• Do not remove a faulty module unless its replacement is on-hand. All modules must be in place
when the system is in operation.
Comply with all ESD precautions. Refer to ESD Precautions on page 165 for additional information.
Illustrations in the controller module replacement procedures show rear panel views of the chassis.
Ensure the RAID controllers and/or expansion IOMs are properly aligned for insertion into the proper
slots.
1 Verify that you have successfully shut down the controller module using the disk management
utility (GUI) or the CLI.
2 Locate the chassis whose UID LED (Ops panel on chassis front left ear) is illuminated, and within
the chassis, locate the controller module whose OK to Remove LED is blue (rear panel).
3 Disconnect any cables connected to the controller.
Label each cable to facilitate re-connection to the replacement RAID controller or expansion IOM.
4 Grasp the module latch between the thumb and forefinger, and squeeze the flange and handle
together to release the latch handle from its docking member (detail No.1), and swing the latch
out to release the RAID controller or expansion IOM from its seated position (detail No.2) as
shown in Figure 144 and Figure 145 .
