Overview: DD9500/DD9800 system DIMMs
DD9500/DD9800 DIMMs are not hot-swappable. The system must be powered down for a
DIMM replacement or addition. Each system contains 8 memory risers and 64 DIMM
slots. Depending on the model, a system contains 256 GB, 512 GB, or 768 GB of memory.
For DD9500 systems:
l256 GB systems contain 32 x 8-GB DIMMs.
lThe upgrade from 256 GB to 512 GB adds an additional 16 x 16 GB DIMMS.
l512 GB systems contain 32 x 8-GB and 16 x16-GB DIMMs.
For DD9800 systems:
l256 GB systems contain 32 x 8-GB DIMMs.

lThe upgrade from 256 GB to 768 GB adds an additional 32 x 16 GB DIMMS.
l768 GB systems contain 32 x 8-GB and 32 x16-GB DIMMs.
The DIMM memory risers are located in the Storage Processor (SP) module which is
accessed from the front of the system. As viewed from the front of the SP module, the
risers are numbered 0-7, with memory riser 7 being on the left.

4. Make a note of the failed DIMM information.
Shut down and disconnect the system
Procedure
1. Run the cifs show active and nfs show active commands to verify that all
I/O on the system is stopped.
2. Reboot the system to verify that no hardware issues exist on the system.
3. Stop the system using the system poweroff command to allow the proper shut
down of the file system and other system components.
If the system that requires a component replacement is the active node of an HA pair,
run the ha status command to verify that the HA pair can failover to the standby
node. Run the ha failover command to initiate 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. In some cases, when you cannot use the system poweroff command, you can
perform a forced shut down of the system by pressing the power button for six
seconds.
Note
The power button is located in the upper right corner on the front panel of DD9500
and DD9800 systems.

Shut down and disconnect the system 7

5. Disengage the wire clips, then disconnect the four AC power cords from the rear of the
system.
Note
Label any cables you remove to make reconnecting them easier.
Remove the bezel
Procedure
1. Remove the bezel on your DD9500/DD9800 system by grasping both hand holds and
pressing toward the center of the bezel until the latches release from the sides of the
chassis. The red circles identify the latches on each bezel.
Figure 3 Removing the bezel
Slide out the storage processor module
The storage processor (SP) is a subassembly that contains the DIMMs and a fan tray with
8 fan modules.
Procedure
1. Unlock the SP module by loosening the single blue thumbscrew.

1. SP module thumbscrew
2. Pull down on the ejector handle.
CAUTION
The handle rotates only to a certain angle. Do not rotate the handle beyond that
position to avoid damage to the handle.
Figure 5 Unlock and pull down the ejector handle
3.
CAUTION
lBe careful the SP has no stop and will easily fall out if pulled too far.
lDo not carry the SP module by the ejector handle.
Using the ejector handle, pull the SP module out and remove it from the chassis to
access the DIMMs. Make sure you have enough space to pull the DIMM drawer out of
the chassis.
CAUTION
Data Domain systems are heavy. Always use two people or a mechanical lift to move
a system. The chassis displays warning signs.
The DIMM memory risers are located in the Storage Processor (SP) module which is
accessed from the front of the system. As viewed from the front of the SP module, the
risers are numbered 0-7, with memory riser 7 being on the left.

CAUTION
lMake sure you are wearing a grounding wrist strap to avoid ESD damage to the
equipment.
lAs required, place all components on an ESD-free work surface.
lFor replacement or upgrade DIMMs, use only DIMMs from a Data Domain memory
spares kit.
Note
To replace a DIMM, identify the location of the failed DIMM inside the memory riser.
Procedure
1. Determine the memory riser that has the failed DIMM and remove that memory riser
for replacement.
2. Push the release button on the memory risers to release the ejector handles. See the
location of the release button in the picture in this section.
3. Remove the riser card by pulling both the ejector handles upward.

8. Install a new DIMM by pushing it into its location in the memory riser. Apply pressure
on both corners of the DIMM until the side release latches automatically get secured.
Avoid pressing the DIMM at the center. Make sure that the replaced DIMM is securely
placed in the slot and connected, otherwise you may get memory alerts when you
verify the DIMMs.
9. Insert the memory riser into the SP module in its correct slot.
10. Push on the two latches to fully seat the memory riser into the SP.
Secure the SP module
Procedure
1. Fully push the SP module into the chassis.

2. Move the SP handle so it is in the stowed position.
3. Secure the SP module by tightening the blue thumbscrew in the middle of the handle.

1. SP module thumbscrew
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.

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
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 the DIMMs
Procedure
1. Power up and system boot.
2. Log in.
3. Enter the system show meminfo command to see the top level summary. Confirm
that the system reports the correct amount of memory. The output, as shown for a 512
GB system, should be similar to the following:
# system show meminfo
Memory Usage Summary
Total memory: 516889 MiB
Free memory: 268231 MiB
Total swap: 5119 MiB
Free swap: 5119 MiB
4. Enter the enclosure show memory command to verify all DIMMs are discovered.
