3. Align the edges of the power supply with the opening in the system chassis
and gently push the power supply into the chassis.
4.
Push on the power supply cam handle to seat it all the way into the chassis,
and then push the cam handle to the closed position, making sure that the cam
handle release latch clicks into its locked position.
5. Reconnect the power cord and secure it to the power supply using the cable
retaining clip.
6. Reconnect the power supply to the power source, and then turn it on. The
power supply should run with no fault LEDs lit.
Note: Reinstall the cable management arm, if you removed it when unplugging
the power supply.
7.
Run diagnostics on the power supply at the next reboot. See the IBM System
Storage System-Level Diagnostics Guide for more information.
Completing the replacement process
Return the failed part to IBM. Contact IBM Service and Support at 1-800-IBM-SERV

Replacing an NVMEM battery or NVMEM DIMMs in an N6200 series
system
To replace an NVMEM battery or NVMEM DIMMs in the system, you must
remove the controller module from the system, open it, replace the battery, and
close and replace the controller module.
About this task
v
This procedure refers to HA pairs , which in releases prior to Data ONTAP 8.0
were called active/active configurations .
v
All other components in the system must be functioning properly; if not,
contact technical support.
Shutting down the node
You shut down a node using different procedures, depending on whether it is a
stand-alone system or part of an HA pair.
Shutting down a node in an HA pair
To shut down the node, you must determine the status of the node and, if
necessary, take over the node so that the partner continues to serve data from the
node's storage.
Before you begin
Note: If your system has two controller modules in the same chassis, you must
leave the power supplies turned on at the end of this procedure to provide power
to the partner node.
Procedure
1. Check the status of the target node (the node you want to perform maintenance
on) by entering the following command at the system console of either node:
