1FRUs
Available FRUs
You can determine which FRUs pertain to your storage 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), I/O modules (IOMs), disk drawers, and power
supplies.
NOTE: See AssuredSAN 4004 Series CLI Reference Guide for more information.
You can also determine which FRUs pertain to your storage 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. Information about FRUs and other
components can also be viewed via RAIDar.

2Procedures
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 about static electricity or assistance with product installation, contact
an authorized reseller.

18 Procedures
Replacing chassis FRU components
Chassis FRUs replace a damaged chassis or chassis components. A fully functional chassis requires
successful installation of the following components:
•Two controller modules of the same model (for a given controller enclosure)*
See Replacing a controller module or expansion module on page 19 for more information.
•Three drawers: each allowing for up to 16 SFF disk drive modules (48 disk drive slots)
See Replacing a drawer on page 26 for more information.
•All disk drive modules and air management modules
See Replacing a disk drive module on page 33 for more information.
•All air management solution (AMS) inserts (if applicable)
See Installing an air management insert on page 34 and Removing an air management insert on
page 35 for more information.
•Two power supply modules of the same type (both AC)
See Replacing a power supply module on page 39 for more information.
•Two ears with components installed (complementary left and right ear kits)
See Replacing ear components on page 43 for more information; also see Figure 3 on page 14 for
2U48 enclosure bezel alignment.
•Two expansion modules of the same model (per optional expansion enclosure)*
See Replacing a controller module or expansion module on page 19 for more information.
*Each I/O module (IOM) slot within the chassis must contain an IOM to enable optimum air flow through the
enclosure during operation. Whether configured as a controller enclosure or a drive enclosure, the Ultra48 Series
chassis supports dual-controller configuration only.
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 46 more information.
•Removal and installation of a 10GbE SFP+ transceiver
See Replacing a 10GbE SFP+ transceiver on page 48 for more information.
•Removal and installation of a 1 Gb RJ-45 SFP transceiver
See Replacing a 1Gb RJ-45 SFP transceiver on page 49 for more information.
•Removal and installation of a storage enclosure chassis
See Replacing a storage enclosure chassis on page 50 for more information.
Replacement of chassis FRU components are described within this chapter.
NOTE: AssuredSAN Ultra48 Series controller enclosures support hot-plug replacement of redundant
controller modules, fans, power supplies, and I/O modules. Hot-add of drawers and drive enclosures is
also supported.
TIP: Many procedures refer to component LEDs and LED statuses. See the AssuredSAN Ultra48 Series
Setup Guide for descriptions of model-specific front panel and rear panel LEDs.
TIP: Within the AssuredSAN Ultra48 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.

AssuredSAN Ultra48 Series FRU Installation and Replacement Guide 19
Replacing a controller module or expansion module
In a dual-controller configuration, controller and expansion modules are hot-swappable, which means you
can replace one module without halting I/O to 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.
You may need to replace a controller module or an expansion module when:
•The Fault/Service Required LED is illuminated
•Health status reporting in RAIDar indicates a problem with the module
•Events in RAIDar indicate a problem with the module
•Troubleshooting indicates a problem with the module
NOTE: Ultra48 Series controller enclosures equipped with CNC controller modules support the
optionally-licensed AssuredRemote™ replication feature; whereas enclosures equipped with SAS controller
modules do not.
CAUTION: When replacing a Ultra48 Series controller set supporting AssuredRemote with a Ultra48
Series controller set that does not support this licensed feature, 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:
•AssuredSAN 4004 Series RAIDar User Guide
•AssuredSAN 4004 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. If replacing both controllers in the dual-control enclosure, use
RAIDar to record configuration settings before installing the new controller modules. See Removing a
controller module or expansion module on page 22, and Installing a controller module or expansion
module on page 24 for instructions.
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. Not doing 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.
When two controller modules are installed in the enclosure, they must be of the same model type. When
replacing both controller modules in an operational enclosure, follow these guidelines:
1. Replace one controller as described in these instructions.
2. Wait 30 minutes: this pause ensures that the controller and its ownership of vdisks has sufficient time to
stabilize (also see Verifying component operation on page 24).
3. Check the system status and event logs to verify that the system is stable.
4. Replace the partner controller as described in these instructions.
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 PFU setting.

20 Procedures
Using RAIDar
IMPORTANT: See the “Updating firmware” topic within the AssuredSAN 4004 Series RAIDar User Guide
before performing a firmware update.
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. Click in the Configuration View panel, right-click the system and select Configuration > Advanced
Settings > Firmware.
3. Either select (check) the Partner Firmware Update check box to enable the option, or clear the check
box to disable the option.
4. Click Apply.
Using the CLI
1. Log-in to the command-line interface 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 4004 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 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
Stopping I/O
When troubleshooting disk drive and connectivity faults, stop I/O to the affected vdisks from all hosts and
remote systems as a data protection precaution. As an additional data protection precaution, it is helpful to
conduct regularly scheduled backups of your data.
IMPORTANT: Stopping I/O to a vdisk is a host-side task, and falls outside the scope of this document.
