FRUs
Available FRUs
You can determine which FRUs pertain to your controller enclosure using the Command-line Interface (CLI).
Access the controller via a telnet client; log into the controller over the network (default user name manage
and password !manage). If the default user or password — or both — have been changed for security
reasons, enter the secure login credentials instead of the defaults shown above.
Enter a show frus query.
Execution of the show frus CLI command displays controller metadata, followed by the FRU
information pertaining to chassis (with midplane), controller module(s), and power supplies.
NOTE:
See AssuredSAN 3000 Series CLI Reference Guide for more information.
You can also determine which FRUs pertain to your controller enclosure by visual inspection of the
component, noting serial number and part number. This method applies to disk drives. FRUs and FRU
make-up are subject to change independent of documentation versions.

Procedures
This chapter provides procedures for replacing FRUs (field-replaceable units), including precautions,
removal instructions, installation instructions, and verification of successful installation. Each procedure
addresses a specific task. Certain procedures refer to related documentation. See Related documentation
on page 9 for a list of these documents and where to find them online.
Electrostatic discharge
Before you begin any of the procedures, consider the following precautions and preventive measures.
Preventing electrostatic discharge
To prevent electrostatic discharge (ESD) from damaging the system, be aware of the precautions to
consider when setting up the system or handling parts. A discharge of static electricity from a finger or
other conductor may damage system boards or other static-sensitive devices. This type of damage may
reduce the life expectancy of the device.
CAUTION:
Parts can be damaged by electrostatic discharge. Follow these precautions:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-protected workstations.
• Place parts in a static-protected area before removing them from their containers.
• Avoid touching pins, leads, or circuitry.
• Always be properly grounded when touching a static-sensitive component or assembly.
• Remove clutter (plastic, vinyl, foam) from the static-protected workstation.
Grounding methods to prevent electrostatic discharge
Several methods are used for grounding. Adhere to the following precautions when handling or installing
electrostatic-sensitive parts.
CAUTION:
Parts can be damaged by electrostatic discharge. Use proper anti-static protection:
• Keep the replacement FRU in the ESD bag until needed; and when removing a FRU from the enclosure,
immediately place it in the ESD bag and anti-static packaging.
• Wear an ESD wrist strap connected by a ground cord to a grounded workstation or unpainted surface
of the computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm (± 10 percent)
resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
• If an ESD wrist strap is unavailable, touch an unpainted surface of the chassis before handling the
component.
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when
standing on conductive floors or dissipating floor mats.
• Use conductive field service tools.
• Use a portable field service kit with a folding static-dissipating work mat.
If you do not have any of the suggested equipment for proper grounding, have an authorized reseller
install the part. For more information on static electricity or assistance with product installation, contact an
authorized reseller.
AssuredSAN 3000 Series FRU Installation and Replacement Guide
27
Replacing chassis FRU components
Chassis FRUs replace a damaged chassis or chassis components. A fully functional chassis requires
successful installation of the following components:
• One or two controller modules of the same model (for a given controller enclosure)*
See Replacing a controller module or expansion module on page 29 for more information.
• All disk drives and air management modules
See Replacing a disk drive module on page 36 for more information.
• Two power supply units of the same type (AC or DC)
See Replacing a power supply module on page 40 for more information.
• Two ear bezels (complementary left and right ear kits)
See Replacing ear bezels on page 46 for more information.
NOTE: Some product models use an enclosure bezel instead of ear covers. If your model is
equipped with a bezel instead of ear covers, see the enclosure bezel kit installation document
provided in your product ship kit:
• See Figure 7 on page 19 for 2U24 enclosure bezel alignment.
• See Figure 14 on page 25 for reduced-depth 2U12 enclosure bezel alignment.
• One or two expansion modules of the same model (per optional drive enclosure)*
Replacing a controller enclosure chassis on page 51 for more information.
*
For enclosures equipped with a single I/O module (IOM), the lower IOM slot within the chassis is empty, and must be covered with
an IOM blank to allow optimum airflow through the enclosure during operation.
In addition to the FRUs identified above, replacement procedures are provided to address specific interface
protocols and replacement of the enclosure chassis:
• Removal and installation of a Fibre Channel transceiver
See Replacing a Fibre Channel transceiver on page 49 for more information.
• Removal and installation of a 10GbE SFP+ module
See Replacing a 10GbE SFP+ transceiver on page 51 for more information.
• Removal and installation of a controller enclosure chassis
See Replacing a controller enclosure chassis on page 51 for more information.
Replacement of chassis FRU components are described within this chapter.
NOTE: AssuredSAN 3000 Series controller enclosures support hot-plug replacement of redundant
controller modules, fans, power supplies, and I/O modules. Hot-add of drive enclosures is also supported.
TIP: Many procedures refer to component LEDs and LED status. See the AssuredSAN 3000 Series Setup
Guide for descriptions of model-specific front panel and rear panel LEDs.
TIP: Within the AssuredSAN 3000 Series Setup Guide, see “Troubleshooting > Fault isolation
methodology” for information about using health icons/values — in addition to using LEDs — for verifying
component failure before actually replacing the FRU.
28
Procedures
Replacing a controller module or expansion module
IMPORTANT: The replacement controller is pre-loaded with TS200 or later firmware. This requires that a
second controller — in a dual-controller configuration — be upgraded to the same code version in order to
operate properly. It is required that the system be upgraded to TS200 or later firmware prior to installing
the replacement controller.
For more information, contact Dot Hill support at 1-877-368-7924 (U.S.); 1-760-931-5500, option 2 (outside
U.S.); e-mail: support@dothill.com.
In a dual-controller configuration, controller and expansion modules are hot-swappable, which means you
can replace one module without halting I/O to virtual disks (vdisks), or powering off the enclosure. In this
case, the second module takes over operation of the storage system until you install the new module.
In a single-controller configuration, you must halt I/O to vdisks, and power off the enclosure. You may
need to replace a controller or expansion module when:
• The Fault/Service Required LED is illuminated
• Events in RAIDar indicate a problem with the module
• Troubleshooting indicates a problem with the module
NOTE: With TS230 or later firmware, 3920/3930, 3723/3733, 3720/3730, 3420/3430, and
3320/3330 models support AssuredRemote replication; whereas 3523/3533 and 3520/3530 models do not.
IMPORTANT: Replication is not supported on 3723/3733 controller enclosures equipped with a single
controller module.
CAUTION: When replacing a 3000 Series controller set supporting AssuredRemote with a 3000 Series
controller set that does not support this licensed feature (e.g., 3520/3530), you must first delete all
replication sets before swapping the controller modules. Not doing so will lead to unexpected results, and
there is no way to delete replication sets after the installation. See the following for additional information:
• Upgrade document supporting your product
• AssuredSAN 3000 Series Using Data Protection Software
• AssuredSAN 3000 Series RAIDar User Guide
• AssuredSAN 3000 Series CLI Reference Guide
Before you begin
Removing a controller or expansion module from an operational enclosure significantly changes air flow
within the enclosure. Openings must be populated for the enclosure to cool properly. Leave modules in the
enclosure until ready to install a replacement. For controller enclosures configured with a single controller
module, a companion IOM blank must be properly installed in the bottom controller module slot.
Single-controller enclosures can be upgraded to dual-controller status. If replacing the controller module in
a single-controller enclosure, or if replacing both controllers in a dual-control enclosure, use RAIDar to
record configuration settings before installing the new controller modules. See Removing a controller
module on page 33, and Installing a controller module or expansion module on page 34 for instructions
on installing an additional controller module.

CAUTION: When replacing a controller module, ensure that less than 10 seconds elapse between
inserting it into a slot and fully latching it in place. Failing to do so might cause the controller to fail. If it is
not latched within 10 seconds, remove the controller module from the slot, and repeat the process.
Configuring partner firmware update
In a dual-controller system in which Partner Firmware Update (PFU) is enabled, when you update firmware
on one controller, the system automatically updates the partner controller. Disable partner firmware update
only if requested by a service technician.
Use RAIDar or the CLI to change the partner firmware update setting.
Using RAIDar
1. Sign-in to RAIDar using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. In the Configuration View panel, right-click the system and select Configuration > Advanced Settings >
Firmware.
3. Either select (enable) or clear (disable) the Partner Firmware Update option.
4. Click Apply.
NOTE:
See AssuredSAN 3000 Series RAIDar User Guide for additional information.
Using the CLI
1. Log-in to the command-line interface (CLI) using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. To verify that partner firmware upgrade is enabled, run the following command:
show advanced-settings
3. If partner firmware upgrade is disabled, enable it by running the following command:
set advanced-settings partner-firmware-upgrade enabled
NOTE:
See AssuredSAN 3000 Series CLI Reference Guide for additional information.
Verifying component failure
Select from the following methods to verify component failure:
• Use RAIDar to check the health icons/values of the system and its components to either ensure that
everything is okay, or to drill down to a problem component. RAIDar uses health icons to show OK,
Degraded, Fault, or Unknown status for the system and its components. If you discover a problem
component, follow the actions in its Health Recommendations field to resolve the problem.
• As an alternative to using RAIDar, you can run the show system command in the CLI to view the
health of the system and its components. If any component has a problem, the system health will be
Degraded, Fault, or Unknown. If you discover a problem component, follow the the actions in its Health
Recommendations field to resolve the problem.
• Monitor event notification — With event notification configured and enabled, use RAIDar to view the
event log, or use the CLI to run the show events detail command to see details for events.
• Check Fault/Service Required LED (back of enclosure): Amber = Fault condition
• Check that the FRU OK LED (back of enclosure) is off
30
Procedures
Stopping I/O
When troubleshooting drive and connectivity faults, ensure you have a current full backup. As an
additional data protection precaution, stop all I/O to the affected vdisks.
IMPORTANT:
Stopping I/O to a vdisk is a host-side task, and falls outside the scope of this document.
When on-site, you can verify that there is no I/O activity by briefly monitoring the system LEDs; however,
when accessing the storage system remotely, this is not possible. Remotely, you can use the show
vdisk-statistics command to determine if input and output has stopped. Perform the steps below:
1. Using the CLI, run the show vdisk-statistics command.
The Number of Reads and Number of Writes outputs show the number of these operations that
have occurred since the statistic was last requested.
2. Run the show vdisk-statistics command a second time.
This provides you a specific window of time (the interval between requesting the statistics) to determine
if data is being written to or read from the disk.
3. If any reads or writes occur during this interval, a host is still reading from or writing to this vdisk.
Continue to stop IOPS from hosts, and repeat step 1 until the Number of Reads and Number of
Writes statistic are zero.
NOTE:
See AssuredSAN 3000 Series CLI Reference Guide for additional information.
Shutting down a controller module
Shutting down the Storage Controller in a controller module ensures that a proper failover sequence is
used, which includes stopping all I/O operations and writing any data in write cache to disk. If the
Storage Controller in both controller modules is shut down, hosts cannot access the system’s data. Perform
a shut down before removing a controller module or powering down the system.
CAUTION: You can continue to use the CLI when either or both Storage Controllers are shut down, but
information shown might be invalid.
Use RAIDar or the CLI to perform a shut down.
Using RAIDar
1. Sign-in to RAIDar using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. In the Configuration View panel, right-click the system and select Tools > Shut Down or Restart
Controller.
3. In the main panel, set the options:
• Select the Shut down operation.
• Select whether to restart the processor in controller A, B, or both.
4. Click Shut down now. A confirmation dialog appears.
5. Click Yes to continue; otherwise click No. If you clicked Yes, a second confirmation dialog appears.
6. Click Yes to continue; otherwise click No. If you clicked Yes, a message describes shutdown activity.
NOTE: If an iSCSI port is connected to a Microsoft Windows host, the following event is recorded
in the Windows event log: Initiator failed to connect to the target.
AssuredSAN 3000 Series FRU Installation and Replacement Guide
31
NOTE:
See AssuredSAN 3000 Series RAIDar User Guide for additional information.
Using the CLI
1. Log-in to the CLI using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. In a dual-controller system, verify that the partner controller is online by running the command:
show redundancy-mode
3. Shut down the failed controller — A or B — by running the command:
shutdown a or shutdown b
The blue OK to Remove LED (back of enclosure) illuminates to indicate that the controller module can
be safely removed.
4. Illuminate the identification LED of the enclosure that contains the controller module to remove by
running the command:
set led enclosure 0 on
NOTE:
See AssuredSAN 3000 Series CLI Reference Guide for additional information.
Removing a controller module or expansion module
IMPORTANT:
• In a single-controller configuration, if you desire to transport CompactFlash to a replacement
controller, remove the controller module only after the cache is copied to CompactFlash, which is
indicated by the Cache Status LED being off. Transporting of cache must be performed by a
qualified service technician.
• In a single-controller environment, you must stop I/O and power off the enclosure before replacing
the controller module.
• In a dual-controller environment, you may hot-replace a controller module in an operational
enclosure, provided you first shut down the faulty controller using either RAIDar or the CLI.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 27.
NOTE: Within these procedures, illustrations featuring controller module face plates are generic. They do
not show host ports, and they pertain to all 3000 Series controller module models. For illustrations of
model-specific controller face plates, see the AssuredSAN 3000 Series Setup Guide.
1. Verify that you have successfully shut down the controller module using RAIDar or the CLI.
2. Locate the enclosure whose Unit Locator LED (front right ear) is illuminated, and within the enclosure,
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.
4. Turn the thumbscrews counterclockwise until they disengage from the controller (see Figure 17 on
page 33).

Installing a controller module or expansion module
TIP: You can install a controller module into an enclosure that is powered on, provided you wait 60
seconds after removing the old controller module. Check controller and midplane power connectors before
inserting the new controller module into the enclosure.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 27.
1. Loosen the thumbscrews; press the latches downward (see Figure 20).
2. Slide the controller module into the enclosure as far as it will go (1).
A controller module that is only partially-seated will prevent optimal performance of the controller
enclosure. Verify that the controller module is fully-seated before continuing.
3. Press the latches upward to engage the controller module (2); turn the thumbscrews clockwise until
finger-tight.

Figure 20 Inserting a controller module
IMPORTANT: In a dual-controller system in which partner firmware update is enabled, when you update
firmware on one controller, the system automatically updates the partner controller.
Verifying component operation
After replacing the controller module, verify that the FRU OK LED (rear panel) illuminates green, indicating
that the controller has completed initializing, and is online/operating normally. It may take two to five
minutes for the replacement controller to become ready. If you are replacing either controller module, and
partner firmware update is enabled, you may need to wait 30 minutes to ensure that the two controllers —
with their respective ownership of the vdisks — have enough time to fully stabilize.
Use RAIDar or the CLI to perform a restart only if necessary.
Using RAIDar
1. Sign-in to RAIDar using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.

Procedures
2. In the Configuration View panel, right-click the system and select Tools > Shut Down or Restart
Controller.
3. In the main panel, set the options:
• Select the Restart operation.
• Select whether to restart the processor in controller A, B, or both.
4. Click Restart now. A confirmation dialog appears.
5. Click Yes to continue; otherwise click No. If you clicked Yes, a second confirmation dialog appears.
6. Click Yes to continue; otherwise click No. If you clicked Yes, a message describes restart activity.
NOTE: If an iSCSI port is connected to a Microsoft Windows host, the following event is recorded
in the Windows event log: A connection to the target was lost, but Initiator
successfully reconnected to the target.
Using the CLI
If the enclosure’s Unit Locator LED is on, run the following command to turn it off:
set led enclosure 0 off
If the Fault/Service Required LED is amber, the controller module has not gone online, and likely failed its
self-test. Put the module online by restarting the controller, or by checking the event log for errors. To restart
the controller (A or B), run the following command:
restart sc a or restart sc b
TIP:
See the AssuredSAN 3000 Series Setup Guide for descriptions of model-specific LEDs.
Updating firmware
You can view the current versions of firmware in controller modules, expansion modules (in drive
enclosures), and disks, and you can also install new firmware versions.
TIP: To ensure success of an online update, select a period of low I/O activity. This helps the update
complete as quickly as possible and avoids disruptions to hosts and applications due to timeouts.
Attempting to update a storage system that is processing a large, I/O-intensive batch job will likely cause
hosts to lose connectivity with the storage system.
A controller enclosure can contain one or two controller modules. In a dual-controller system, both
controllers should run the same firmware version. Storage systems in a replication set must run the same
firmware version. You can update the firmware in each controller module by loading a firmware file
obtained from the enclosure vendor.
If you have a dual-controller system and the PFU option is enabled, when you update one controller, the
system automatically updates the partner controller. If PFU is disabled, after updating firmware on one
controller, you must log into the partner controller’s IP address and perform this firmware update on that
controller also.
NOTE: If a vdisk is quarantined, firmware update is not permitted due to the risk of losing unwritten data
that remains in cache for the vdisk volumes. Before you can update firmware, you must resolve the problem
that is causing the vdisk to be quarantined, as described in the “Removing a vdisk from quarantine” topic
in the RAIDar user guide or online help.
For best results, the storage system should be in a healthy state before starting firmware update.
AssuredSAN 3000 Series FRU Installation and Replacement Guide
35
You can update firmware using RAIDar or using FTP (File Transfer Protocol). See the AssuredSAN 3000
Series RAIDar User Guide for more information.
Replacing a disk drive module
A disk drive module consists of a disk in a sled. Disk drive modules are hot-swappable, which means they
can be replaced without halting I/O to the vdisks, or powering off the enclosure. The new disk drive
module must be of the same type, and possess capacity equal to or greater than the one being replaced.
Otherwise, the storage system cannot use the new disk to reconstruct the vdisk (see “About vdisks” and
“About disk failure and vdisk reconstruction” topics in the RAIDar user guide).
Air management modules
An air management module looks like a disk drive module; however, it is an empty box — also known as
a blank — used to maintain optimum air flow for proper cooling within an enclosure. Air management
modules are installed in slots missing disk drive modules. If you must remove a disk drive module, but
cannot immediately replace it, you must either leave the faulty module in place, or insert an air
management module in its place.
The blank is installed using the same procedure as Installing a disk drive module on page 38. Similarly,
the blank is removed using the same procedures as Removing a disk drive module on page 36.
Before you begin
CAUTION: Removing either a disk drive module or blank impacts the airflow and cooling ability of the
enclosure. If the internal temperature exceeds acceptable limits, the enclosure may overheat, and
automatically shut down or restart. To avoid potential overheating, wait 20 seconds to allow the internal
disks to stop spinning, then insert the new disk drive module or blank.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 27.
Verifying component failure
Before replacing a disk, perform the following steps to ensure that you have correctly identified the module
requiring removal and replacement.
CAUTION: Failure to identify the correct disk drive module could result in data loss if the wrong disk is
removed from the enclosure.
When a disk drive fault occurs, the failed disk’s fault indicator LED, located on the enclosure’s front panel,
illuminates solid amber (see the AssuredSAN 3000 Series Setup Guide for a description of LEDs and disk
drive slot numbering for your enclosure). You can determine from visual inspection which disk in the
enclosure is experiencing a fault/failure using the fault LED for your disk type.
NOTE: For enclosures equipped with a dust filtration bezel, you must remove the bezel to view the disk
drive LEDs. Enclosure status LEDs are visible on the labeled bezel.
See the enclosure bezel kit installation document in your product ship kit for information about removing
and installing the bezel, or for instructions about servicing or replacing the bezel air filter. Alternatively, you
can observe disk component health using management interfaces to verify component failure or
component operation (see Using management interfaces on page 55 for more information).
Removing a disk drive module
1. Follow one of the three sub-steps below, according to your product disk drive type (see Figure 21 on
page 37):

The installed disk drive module should now appear as shown in Figure 21 on page 37.
NOTE: Allow at least 30 seconds to elapse when jointly completing the “Removing a disk drive
module” and “Installing a disk drive module” procedures.
If using RAIDar, execute steps 4 and 5 to complete this procedure. If using the CLI, execute steps 6 and
7 to complete this procedure.
Using RAIDar:
4. Sign in to RAIDar (use default user manage and password !manage, or the appropriate username and
password if they have been changed).
5. View the System Overview panel to determine whether the health of the new disk is OK. If the health is
OK, then the disk drive module installation process is complete. If the health is not OK, then in the
Configuration View panel, select the enclosure that the new disk is in to display the Enclosure Overview
panel, then select the disk and view details about it, such as Status and Health Recommendations.
AssuredSAN 3000 Series FRU Installation and Replacement Guide

Using the CLI:
6. Log in to the CLI (use default user manage and password !manage, or the appropriate username and
password if they have been changed).
7. To view information about disks, run the following command:
show disks <disk-ID>
Disks are specified by enclosure ID and slot number. Enclosure IDs increment from 1. Disk IDs increment
from 1 in each enclosure (e.g., show disks 1.7). Entering the command shown above will display the
disk health. If health is not OK, the command output will also display recommended actions.
Determine if a disk is missing
You can determine whether a disk is missing by using management interfaces.

1. Sign-in to RAIDar using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. In the Configuration View panel, right-click on the appropriate enclosure under Physical.
• Select the Front Graphical tab to display a pictorial representation of disks within slots and the
supporting enclosure table showing properties and values.
• Select the Front Tabular tab to display the Enclosure’s Front View data table and supporting
enclosure table showing properties and values.
3. Using the graphical and tabular views, look for gaps in the disk location sequence to determine if a
disk is missing.
Using the CLI
1. Log-in to the command-line interface (CLI) using default user manage and password !manage.
If the default user or password — or both — have been changed for security reasons, enter the secure
login credentials instead of the system defaults shown above.
2. To determine location of a missing or faulty drive, run the following command:
show disks
The command outputs a listing of detected disks’ properties by location. Review the information, and
look for gaps in the disk location sequence to determine whether any disks are missing.
Verifying component operation
Check that the Power/Activity/Fault LED (LFF disks) or Power/Activity LED (SFF disks) — located on the
front face of the disk drive’s escutcheon — is illuminated green. On LFF disks, this is the bottom LED. On
SFF disks, this is the left LED. Both sets of LEDs are shown in Figure 23 on page 39.
TIP: See the AssuredSAN 3000 Series Setup Guide for descriptions of disk drive LEDs and other front
panel LEDs pertaining to 2U12 and 2U24 controller enclosures.
Also see Using management interfaces on page 55 as an alternative to physically observing LEDs to verify
component operation.
Replacing a power supply module
This section provides procedures for replacing a failed AC or DC power supply module, also referred to as
a power supply unit (PSU).
CAUTION: Power supply FRU replacement activities can cause enclosure cables to disconnect and disks
to go offline.
40
Procedures
When replacing a power supply FRU, you might accidentally disconnect cables, causing disks to go
offline. As a precaution — before installing or replacing a FRU — you should stop I/O to all vdisks. If
stopping I/O is not possible, the next best action is to defer FRU replacement until such time as it is
possible to stop all I/O. If immediate replacement is necessary during I/O, ensure that all cables are
securely fastened, and proceed with great caution as you replace the power supply FRU within the
controller enclosure. Be very careful if moving a cabled/operational enclosure during the FRU replacement
process.
A single PSU is sufficient to maintain operation of the enclosure. You need not halt operations and
completely power-off the enclosure when replacing only one PSU; however, a complete shutdown is
required if replacing both power supply units.
TIP:
Power supply faults and recommended actions on page 41 provides additional information.
Before you begin
CAUTION: Removing a power supply unit significantly disrupts the enclosure’s airflow. Do not remove the
PSU until you have received the replacement module.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 27.
Verifying component failure
When either a fan or power supply component fails, RAIDar provides notification; faults are recorded in
the event log; and the PSU’s status LED color changes to amber to indicate a fault condition.

Ensure that no slots are left open for more than 2
minutes. If you must replace the FRU, leave the old
module in place until the replacement arrives to
maintain optimal airflow and avoid overheating.
Verify that the power supply module is powered on.
If your power supply module has a power switch,
verify that it is switched on.
Verify that the power cables are securely attached to
the power supply module and the appropriate power
source.

Power supply units
IMPORTANT: Newer AC power supply units do not have power switches. These PSUs power on when
connected to a power source, and power off when disconnected.
Power cycling procedures vary according to the type of power supply included within the enclosure. For
controller and expansion enclosures configured with AC PSUs that do not have power switches, refer to the
procedure described under AC PSU below. For procedures pertaining to a) controller enclosures
configured with DC PSUs, or b) previously installed drive enclosures featuring power switches, see DC and
AC PSUs with power switch on page 43.
NOTE: AC PSUs — with or without a power switch — are compatible with one another in that the two
different models can coexist in the same enclosure, and are interchangeable.
AC PSU
Enclosures configured with AC PSUs that do not have a power switch rely on the power cord for power
cycling. Connecting the cord from the PSU power cord connector to the appropriate power source
facilitates power on; whereas disconnecting the cord from the power source facilitates power off.
Power cord connect
Figure 24 AC PSU
Powering off the PSU
1. Stop all I/O from hosts to the enclosure (see Stopping I/O on page 31).
2. Use management software to shut down any other system components necessary.
Given that power switch shut-off does not apply to this particular power supply model, proceed to
disconnecting the AC power cord.
Disconnecting an AC power cord
1. Disconnect the power cord’s male plug from the power source.
2. Disconnect the power cord’s female plug from the power cord connector on the PSU.
NOTE: See Connecting a power cable on page 45 for an illustration showing AC power cord

2. Loosen the cable-locking screws that attach each D-shell connector to its power supply, and carefully
disconnect the lugs on each cable wire component of the DC power cable from the DC power source
(Figure 28 on page 45 shows cable wire lugs and D-shell connector).
3. Loosen the cable-locking screws attaching the D-shell connector to the PSU, and disconnect the power
cable from the PSU.
Removing a power supply unit
1. If replacing a single power supply module via hot-swap, proceed to step3.
2. If replacing both power supply modules, verify that the enclosure is powered off.
If the PSU model has a power switch, verify that the switch is set to the Off position.
3. Verify that the power cord is disconnected.
4. Turn the thumbscrew at the top of the latch counterclockwise to loosen and disengage it from the
module; however, do not remove the thumbscrew from the latch.
5. Rotate the latch downward by approximately 45° supplying leverage to disconnect the module from the

Procedures
Replacing a Fibre Channel transceiver
This section provides steps for replacing a small form-factor pluggable (SFP transceiver) connector used in a
Fibre Channel (FC) controller host port. An example SFP connector is shown below.
Figure 32 Sample SFP connector
Before you begin
CAUTION: Mishandling fibre-optic cables can degrade performance. Do not twist, fold, pinch, or step on
fibre-optic cables. Do not bend them tighter than a 2-inch radius.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 27.
CAUTION: To prevent potential loss of access to data, be sure to identify the correct cable and SFP
connector for subsequent removal.
Verifying component failure
Transceivers are part of a data path that includes multiple components, such as the transceiver, a cable,
another SFP, and an HBA (host bus adapter). A reported fault can be caused by any component in the
data path. To identify the location of the fault, check the Link Status and Activity LEDs on the controller
enclosure and server. Also, check the cable for kinks, crimping or other possible damage.
TIP:
See the AssuredSAN 3000 Series Setup Guide for descriptions of rear panel LEDs.
Removing an SFP module
Perform the following procedure to remove an SFP connector. When removing an FC SFP that has
previously limited the port speed — and replacing it with a higher-rated SFP — it is possible, though rare,
that auto-negotiation will not enable the higher port speed. Rebooting the array or the host resolves the
problem.
1. Disconnect the fibre-optic interface cable by squeezing the end of the cable connector.
If the SFP does not have a cable, it should have a plug (retained from installation).
AssuredSAN 3000 Series FRU Installation and Replacement Guide

3. Grasp the SFP between your thumb and index finger, and carefully remove it from the controller
module.
Installing an SFP module
Perform the following procedure to install an SFP connector.
1. To connect to an empty port, slide the SFP connector into the port until it locks into place.
If the SFP has a plug, remove it before sliding the connector into the FC port. Retain the plug.
2. Flip the actuator down.
Flip actuator/revolve downwards

Verifying component operation
View the Link Status and Link Activity LEDs on the controller module face plate. A blinking LED indicates
that no link is detected. Also check the link status and link activity LEDs on the host.
Replacing a 10GbE SFP+ transceiver
This section provides steps for removing and replacing a small form-factor pluggable plus (SFP+
transceiver) connector used in an Internet SCSI (iSCSI) controller host port. SFP+ connectors are similar in
appearance to SFP connectors. These transceivers enable 10GbE equipment designs with high port
density, based on electrical and mechanical enhancements to SFP specifications developed by the Small
Form Factor (SFF) Committee.
Removing and replacing an SFP+ consists of the same basic steps described for removing and replacing
an SFP in the preceding section. This procedure refers to the preceding Replacing a Fibre Channel
transceiver procedure. When reviewing the procedure as it pertains to the 10Gb iSCSI host ports, note that
your particular cables may be either copper or fibre-optic for the SFP+, depending upon how your system
was initially configured, and the SFP+ option used.
Table 9
Removing and replacing a 10GbE SFP+ transceiver
To accomplish this sequential process
See the following procedures
1. Remove SFP+ connector.
a. Before you begin on page 49.
b. Verifying component failure on page 49.
c. Removing an SFP module on page 49.
2. Install the replacement SFP+ connector.
Installing an SFP module on page 50.
3. Verify proper operation for the removed and
installed FRU component.
Verifying component operation on page 51.
Replacing a controller enclosure chassis
The controller enclosure chassis replacement procedure replaces a damaged chassis FRU, which consists
of the structural support metal, the exterior sheet metal housing, and the assembled/installed midplane.
The procedure includes removing all FRU components from a damaged chassis and installing them in a
replacement chassis.
NOTE: AssuredSAN 2U24 and 2U12 controller enclosure chassis models are described in FRUs
addressing 24-drive enclosures on page 14 and FRUs addressing 12-drive enclosures on page 20.
AssuredSAN 3000 Series FRU Installation and Replacement Guide
51
Whether your controller enclosure product is a 2U24 or 2U12 model, a fully functional replacement
chassis requires the successful removal and installation of the following components:
• All disk drive modules and air management modules
• Two ear bezels (for left and right ears)
Some models use an enclosure bezel instead of left and right ear covers
• Two power supply units of the same type (both AC or both DC)
• One or two controller modules (of the same model type) and possibly an I/O module blank (for
single-controller enclosures)
Certain models also require the successful removal and installation of the following components:
• Fibre Channel transceiver (SFP for 3920/3930, 3723/3733, and 3720/3730 models)
• 10GbE SFP+ transceiver (SFP+ option for 3420/3430 models)
This procedure makes extensive use of the FRU component procedures described elsewhere in Chapter 2.
Perform this procedure by following the step-by-step process described below.
Before you begin
CAUTION:
Do not remove the enclosure until you have received the replacement enclosure.
See CAUTION bullets regarding “electrostatic discharge” and “anti-static protection” on page 27.
1. Schedule down time that will allow for shutdown; sixty minutes of replacement work; and restart.
2. Verify the existence of a known/good backup of the system.
3. Record system settings for future use.
4. Label all cables.
5. Prepare a suitable work environment to accommodate chassis replacement.
Verifying component failure
The controller enclosure FRU includes the enclosure’s metal housing and the midplane that connects
controller modules, disk drive modules, and power supply modules. This FRU replaces an enclosure that
has been damaged, or whose midplane has been damaged.
Often times, a damaged midplane will appear as though a controller module has failed. If you replace a
controller module, and it does not remedy the fault, you may need to replace the enclosure.
Alternatively, you can observe enclosure health (front panel and rear panel) using management interfaces
to verify enclosure/component failure or enclosure/component operation (see Using management
interfaces on page 55 for more information).
Preparing to remove a damaged storage enclosure chassis
Since you are removing and replacing an entire controller enclosure, neither the hot-swap capability that
applies to replacing individual redundant FRUs in an operational controller enclosure, nor the hot-add of a
drive enclosure to an operational storage system, apply to this procedure.
1. Stop all I/O from hosts to the system. See Stopping I/O on page 31.
2. Shut down the controller(s). See Shutting down a controller module on page 31.
3. Power off the system (controller enclosure first; drive enclosure(s) next). See Power supply units on
page 42, and refer to the power cycling procedures pertaining to your enclosure’s power supply
modules.

5. Remove the side bracket from each side of the damaged controller enclosure chassis.
6. Attach the side bracket to each side of the replacement controller enclosure chassis.
Installing the replacement storage enclosure chassis in the rack
This section provides a procedure for installing the replacement controller enclosure chassis in its rack
location.
CAUTION: It is recommended that all disk drive modules and air management modules be removed
before lifting the enclosure. If this is not possible, two people are required to move the enclosure. See
Removing a disk drive module on page 36.
NOTE: Refer to Rackmount Bracket Kit Installation or 2-Post Rackmount Bracket Kit Installation for the
correct installation procedure and mounting hardware.
1. Attach side brackets (standard rackmount installation) or main brackets (2-post rackmount installation)
on the replacement controller enclosure chassis.
2. Support the bottom of the controller enclosure chassis. Carefully lift/align the chassis and slide it into
the rack.
3. Using the appropriate mounting hardware, secure the controller enclosure chassis to the rack.
4. Install the ear bezels. See Installing ear bezel components on page 48.
5. Using the applicable retaining screws, secure the front and rear of the controller enclosure chassis to
the rack and rails.
Completing the process
This section provides a procedure for ensuring that the FRU components installed in the replacement
controller enclosure chassis function properly.
1. Reconnect data cables between devices, as needed, to return to the original cabling configuration:
• Between cascaded enclosures.
• Between the controller and peripheral or SAN devices.
• Between the controller enclosure and the host.
2. Reconnect power cables to the controller enclosure. See Connecting a power cable on page 45.
3. Turn on the power switch to power supply modules if they are equipped with power switches.
54
Procedures
NOTE: For powering-on AC PSUs with or without a power switch, and DC and AC PSUs with a power
switch, see Power supply units on page 42.
Verifying component operation
Restart system devices in the following sequence. Allow time for each device to complete its Power On Self
Tests (POST) before proceeding:
1. Disk drive enclosures
2. Controller enclosure
3. Host (if powered down for maintenance)
Using LEDs
View LEDs on the front and rear of the enclosure (see “LED descriptions” within the AssuredSAN 3000
Series Setup Guide for more information).
Verify front panel LEDs:
• Verify that the Enclosure ID LED (located on the left ear) is illuminated green.
• Verify that the FRU OK and Temperature Fault LEDs are illuminated green, and that the Fault/Service
Required LED is off (all three LEDs are located on the right ear).
• For LFF disks, verify that the Power/Activity/Fault LED (bottom LED on front of disk) is illuminated green
or blinking green (If your product model has an enclosure bezel, remove it to view disk LEDs).
• For SFF disks, verify that the Power/Activity LED (left LED on front of disk) is illuminated green or
blinking green (If your product model has an enclosure bezel, remove it to view disk LEDs).
Verify rear panel LEDs:
• Verify that the each power supply module’s Input Source Power Good LED (top LED on PSU) is
illuminated green.
• Verify that the FRU OK LED on each IOM face plate is illuminated green, indicating that the module
has completed initializing, and is online.
Using management interfaces
In addition to viewing LEDs as described above, you can use management interfaces to monitor the health
status of the system and its components, provided you have configured and provisioned the system (see
“Getting Started” within the AssuredSAN 3000 Series RAIDar User Guide for more information).
Select from the following methods to verify component operation:
• Use RAIDar to check the health icons/values of the system and its components to either ensure that
everything is okay, or to drill down to a problem component. RAIDar uses health icons to show OK,
Degraded, Fault, or Unknown status for the system and its components. If you discover a problem
component, follow the actions in its Health Recommendations field to resolve the problem.
• As an alternative to using RAIDar, you can run the show system command in the CLI to view the
health of the system and its components. If any component has a problem, the system health will be
Degraded, Fault, or Unknown. If you discover a problem component, follow the actions in its Health
Recommendations field to resolve the problem.
• Monitor event notification — With event notification configured and enabled, you can view event logs
to monitor the health of the system and its components. If a message tells you to check whether an event
has been logged, or to view information about an event in the log, you can do so using either RAIDar
or the CLI. Using RAIDar, you would view the event log and then click on the event message to see
detail about that event. Using the CLI, you would run the show events detail command (with
additional parameters to filter the output) to see the detail for an event (see “Alphabetical list of
commands > show events” within the AssuredSAN 3000 Series CLI Reference Guide for more
information about command syntax and parameters).
