Remove and install the NVRAM module
The following instructions describe how to remove and install the NVRAM module.
NVRAM Module Replacement
Remove and install the NVRAM module 5

CAUTION
lThe NVRAM module is not hot swappable. The system must be powered down.
lOnly trained and qualified personnel should be allowed to install or replace this
equipment.
lDuring the procedure, wear a grounding wrist strap to avoid ESD damage to the
equipment.
Shut down and disconnect the system
Procedure
1. Disable the filesystem using the filesys disable command.
Note
If the filesystem is not shut down, you will not be able to erase the data from the
NVRAM and you will get a message such as **** This operation is not
allowed when the filesystem is enabled **** Error retrieving
information (This operation is not allowed when the
filesystem is enabled).
2. After the filesystem is shutdown, erase the data from the NVRAM, by entering the
system erase nvram-flash command.
Note
You must be a qualified personnel with the sysadmin user privilege to use this
command, otherwise you will get a message such as **** This command is not
available for this user.
Note
If the NVRAM is preventing the system to boot and the system erase nvram-
flash command cannot be used to erase the NVRAM, run the offline diagnostic
utility Erase NVRAM data. For details about the offline diagnostic utility, see the
EMC Data Domain Operating System Offline Diagnostics Suite User's Guide for your
release.
3. Stop the system using the system poweroff command to allow the proper shut
down of the filesystem and other system components.
If the system that requires NVRAM replacement is the active node of an HA pair, run
the ha failover command to failover to the standby node before replacing a
component. The failover process takes 10 minutes to complete.
Note
The system poweroff command completes when the front panel blue LED turns
off.
For help connecting to a system using a laptop computer and terminal emulator, see
the document FE Toolkit Inventory and Common Procedures for FRU Tasks at https://
support.emc.com.

4. Disengage the wire clips, then disconnect the four AC power cords from the rear of the
system.
Remove and install an NVRAM module
Note
lPlace modules on a clean ESD-protected work surface.
lBe careful not to touch the components on the module.
lThe NVRAM module, located in slot 0, is removed and inserted similar to the other I/O
modules.
Procedure
1. Move the cable management assembly (CMA) arms out of the way to access the
NVRAM module.
2. Grasp the blue handle trigger to release the NVRAM module. The ejector button
should release.
Note
Do not remove the NVRAM until the ejector button has released and popped out.
Figure 2 NVRAM module ejector handle (rear of system)
3. Pull on the handle to remove the module from the chassis.
4. Align and slide a replacement module into the bay until it seats in its connector.
5. Apply firm pressure on the front of the module until it seats fully into the slot.
6. Push the ejector button in to secure the module.

Remove and install an NVRAM module 7

Note
The blue ejector indicates that the module is correctly seated. If the blue ejector
button does not remain seated, then the module is not fully inserted. Push on the
module handle to complete the seating process.
Reconnect the system
Procedure
1. Engage power by reconnecting all AC power cords.
2. Reconnect the wire clips for the AC cords.
3. Check to see that the service LED on the Management module glows green.
Note
The service LED lights up within 30 seconds after you connect the AC power cords.
4. In the front of the DD9500/DD9800 system, press the power button to turn the power
on the system.
5. Check that the front blue power LED (with the circle with a dot) also turns on.

2. Power button
6. For HA systems that were failed over to the standby node before the component
replacement, optionally fail the ssytem back to the original active node. Run the ha
Field Replacement Guide
8EMC Data Domain DD9500 and DD9800 Systems Field Replacement Guide

status command to verify that the HA pair can failover and the ha failover on
the current active node to restore the original active node.
Verify NVRAM
Procedure
1. Enter the enclosure show chassis command to check the battery and NVRAM
chassis status.
Note
The NVRAM battery might take up to 1.5 hours to get fully (100%) charged depending
on how discharged the NVRAM battery is at the time of the installation. However the
filesystem is enabled when the battery capacity is above 80%, which should take a
shorter time.
2. Enter the system show hardware command to check information about the
NVRAM module.
3. Enter the system show nvram command to check battery and NVRAM status.

Procedure
1. Return the failed or replaced part(s) to EMC Data Domain. Reuse the packaging from
the new part(s) and use the included prepaid waybill for shipping. Reference the RMA
number on the outside of the package.
2. Send an autosupport report from the system by entering the autosupport send
command.
