Hardware replacement overview
Some hardware components of the Integrated Data Protection Appliance (IDPA) DP4400 can be
replaced without shutting down the system, and some hardware components require a system
shutdown to replace.
The target audience for this document is resources who are responsible for replacing IDPA
DP4400 components.
The following table lists the IDPA DP4400 components and whether it is required that they be shut
down while being replaced. To replace one of these components, go to the required replacement
procedure.

Figure 1 Product serial number tag
Note: The PSNT may contain multiple serial number stickers. The serial number for the
DP4400 is on a white sticker that has a part number starting with 900 printed on it.
Shut down the IDPA
You can shut down the IDPA appliance from the ACM console.
Before you begin
lEnsure that there are no backup jobs running on the Avamar Backup Server.
Note:
nIf there are backup jobs running on Avamar Backup Server when the IDPA appliance
shutdown operation is in progress, the shutdown operation waits for the Avamar jobs to
complete with the status Waiting for shutdown of Backup Server.
nIt is recommended that you wait for the backup jobs to complete. However, if you must
shut down the appliance immediately, and then you must log in to the Avamar UI and
cancel the backup jobs that are in progress.
lShutting down the IDPA appliance requires physical intervention or the use of iDRAC to restart
the system. If you are remotely shutting down the IDPA appliances, ensure that either you
have physical access to the system or have configured iDRAC on the system.
About this task
To shut down IDPA, perform the following actions:
Procedure
1. On the ACM dashboard Home tab, click the Shutdown Appliance icon.
2. Enter the ACM root password, and click Yes.
The appliance shut down progress is displayed.
The IDPA appliance shuts down the components in the following order:
lBackup Server
lSearch
lReporting and Analytics
lSystem Manager
lCloud Disaster Recovery Agent
lProtection Storage

Dell EMC Integrated Data Protection Appliance DP4400 Service Procedures 9

lAppliance Configuration Manager
lvCenter Server
lCompute Node
If the ACM-initiated shutdown fails to shut down the Backup Server and the Protection
Storage or both, then the ACM displays a message listing the component(s) that failed to
shut down. The ACM then continues to shut down the other components.
If any components fail to shut down, you must manually shut down the components. For
more information about manual shut down of IDPA components, see Troubleshooting shut
down.
Troubleshooting shutdown of the DP4400
If any part of the shutdown process fails to complete automatically, troubleshoot as follows.
Procedure
1. Login to the Avamar server with SSH by using the Avamar IP address.
2. Create a checkpoint by running the following command:
mccli checkpoint create --override_maintenance_scheduler
3. Verify that the checkpoint was created by running the following command:
status.dpn
4. Stop all Avamar services by running the following command:
dpnctl stop all
5. Log in to the Data Domain with SSH using the Data Domain IP address.
6. Shut down the Data Domain system by running the following command:
system poweroff
7. Open the vCenter by typing the IP address in the browser.
8. Log in to vCenter by using the customer-specified username and password. If the ACM is
down, connect to VC and ESX using username "idpauser" and appliance password as a
password.
9. Power off the Data Protection virtual application.
All virtual machines and virtual applications under the Data Protection virtual application are
automatically shut down.
10. Shut down the IDPA Virtual Machine guest operating system, and power off the virtual
machine.
11. Log in to the ESXi server on which the vCenter resides.
12. Log in to each ESXi host.
13. Place each ESXi host into maintenance mode by running the following command on each
host:

Remove and replace power supply
Power supply units
The power supply unit (PSU) is an internal hardware component which supplies power to the
components in the system.
Your system supports two 750 W Mixed Mode HVDC PSUs.
You do not need to shut down the system to replace a power supply unit.
CAUTION If two PSUs are installed, both the PSUs must have the same type of label. For
example, Extended Power Performance (EPP) label. Mixing PSUs from previous generations
of PowerEdge servers is not supported, even if the PSUs have the same power rating. Mixing
PSUs will result in mismatch condition or failure to turn the system on.
Power supply status indicators
Status LED indicators
Note: The status LED indicators are always off and only turn on to a solid amber if any error
occurs.

configuration utility program.
Temperature
indicator
The indicator turns
solid amber if the
system experiences a
thermal error (for
example, the ambient
temperature is out of
range or there is a fan
failure).
Ensure that none of the following
conditions exist:
lA cooling fan has been removed or
has failed.
lSystem cover, air shroud, memory
module blank, or back filler bracket
is removed.
lAmbient temperature is too high.
lExternal airflow is obstructed.
Electrical
indicator
The indicator turns
solid amber if the
system experiences
an electrical error (for
example, voltage out
of range, or a failed
power supply unit
(PSU) or voltage
regulator).
Check the System Event Log or system
messages for the specific issue. If it is
due to a problem with the PSU, check
the LED on the PSU. Reseat the PSU.
Memory
indicator
The indicator turns
solid amber if a
memory error occurs.
Check the System Event Log or system
messages for the location of the failed
memory. Reseat the memory module

14 Dell EMC Integrated Data Protection Appliance DP4400 Service Procedures

1. AC PSU status indicator/handle
This table describes the AC PSU status indicators and what condition is the PSU when the power
indicator light is green, blinking green, blinking amber, and when it is not lit.
Power indicator
codes
Condition
Green A valid power source is connected to the PSU and the PSU is operational.
Blinking amber Indicates a problem with the PSU.
Not illuminated Power is not connected to the PSU.
Blinking green When the firmware of the PSU is being updated, the PSU handle blinks
green.
CAUTION Do not disconnect the power cord or unplug the PSU when
updating firmware. If firmware update is interrupted, the PSUs do not
function.
Blinking green and
turns off
When hot-plugging a PSU, the PSU handle blinks green five times at a
rate of 4 Hz and turns off. This indicates a PSU mismatch with respect to
efficiency, feature set, health status, or supported voltage.
CAUTION If two PSUs are installed, both the PSUs must have the
same type of label; for example, Extended Power Performance (EPP)
label. Mixing PSUs from previous generations of PowerEdge servers
is not supported, even if the PSUs have the same power rating. This
results in a PSU mismatch condition or failure to turn the system on.
CAUTION When correcting a PSU mismatch, replace only the PSU
with the blinking indicator. Swapping the PSU to make a matched pair
can result in an error condition and unexpected system shutdown. To
change from a high output configuration to a low output configuration
or vice versa, you must turn off the system.
CAUTION AC PSUs support both 240 V and 120 V input voltages with
the exception of Titanium PSUs, which support only 240 V. When two
identical PSUs receive different input voltages, they can output
different wattages, and trigger a mismatch.
CAUTION If two PSUs are used, they must be of the same type and
have the same maximum output power.
CAUTION Combining AC and DC PSUs is not supported and triggers
a mismatch.

For systems that support redundant PSU, ensure that both the PSUs are of the same type and
have the same maximum output power.
Note: The maximum output power (shown in watts) is listed on the PSU label.
Procedure
1. Slide the PSU into the system until the PSU is fully seated and the release latch snaps into
place.
2. If you have unlatched the cable management arm, relatch it.
3. Connect the power cable to the PSU, and plug the cable into a power outlet.
CAUTION When connecting the power cable to the PSU, secure the cable to the PSU
with the strap.
Note: When installing, hot swapping, or hot adding a new PSU, wait for 15 seconds for
the system to recognize the PSU and determine its status. The PSU redundancy may
not occur until discovery is complete. Wait until the new PSU is discovered and enabled
before you remove the other PSU. The PSU status indicator turns green to signify that
the PSU is functioning properly.
