AssuredSAN Ultra48 Series FRU Installation and Replacement Guide 7
About this guide
Overview
This guide identifies Ultra48 Series FRUs (field-replaceable units), and describes how to remove or install
them within the AssuredSAN™ Ultra48 Series storage enclosure products listed below:
•CNC (Converged Network Controller) Controller enclosure (4844 models):
• Qualified Fibre Channel SFP option supporting (4/8/16 Gb)
• Qualified Internet SCSI (10GbE) SFP option
• Qualified Internet SCSI (1 Gb) Copper RJ-45 SFP option
•HD mini-SAS (12 Gb) Controller enclosure: 4544
For a complete description of product models, see the “Components” chapter within the Setup Guide.
AssuredSAN Ultra48 Series enclosures support both traditional linear storage and new virtual storage,
which uses paged-storage technology. For linear storage, a group of disks with an assigned RAID level is
called a vdisk or linear disk group. For virtual storage, a group of disks with an assigned RAID level is
called a virtual disk group. This guide uses the term vdisk when specifically referring to linear storage, and
uses the term disk group otherwise.
AssuredSAN Ultra48 Series enclosure user interfaces
The Ultra48 Series enclosures support two versions of the web-based application for configuring,
monitoring, and managing the storage system. Both web-based application GUI versions (v3 and v2), and
the command-line interface are briefly described:
•Storage Management Console (SMC) is the new primary web interface (v3) for the enclosures,
providing access to all common management functions for both linear and virtual storage.
•RAIDar is a secondary web interface (v2) for the enclosures, providing access to traditional linear
storage functions. This legacy interface provides certain functionality that is not available in the primary
interface.
•The command-line interface (CLI) enables you to interact with the storage system using command syntax
entered via the keyboard or scripting. You can set a CLI preference to use v3 or v2 terminology in
command output and system messages.
NOTE: For more information about enclosure user interfaces, see the following:
•AssuredSAN Ultra48 Series Storage Management Guide or online help
The guide describes SMC (v3) and RAIDar (v2) GUIs

10 FRUs
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 the SMC or 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 8 for a list of these documents and where to find them online.
IMPORTANT: Procedures pertain to FRUs used in Ultra48 Series (2U48) products. Procedures pertaining to
FRUs used in 2U12, 2U24, and 4U56 chassis are described in 4004 and Ultra56 documentation
.
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.

18 Procedures
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.
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 20 for more information.
•All disk drive modules (inserted into three pre-installed drawers within the chassis)
See Accessing a drawer on page 29 for more information.
See Replacing a disk drive module on page 30 for more information.
•All air management solution (AMS) inserts (if applicable)
See Installing an air management insert on page 32 and Removing an air management insert on
page 33 for more information.
•Two power supply modules of the same type (both AC)
See Replacing a power supply module on page 38 for more information.
•Two ears with components installed (complementary left and right ear kits)
See Replacing ear components on page 42 for more information; also see Figure 7 on page 19 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 20 for more information.
*Each I/O module (IOM) slot within the chassis must contain an IOM to enable sufficient 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. Single-controller support is provided only when a controller fails over to its
partner controller.
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 45 more information.
•Removal and installation of a 10GbE SFP+ transceiver
See Replacing a 10GbE SFP+ transceiver on page 47 for more information.
•Removal and installation of a 1 Gb RJ-45 SFP transceiver
See Replacing a 1Gb RJ-45 SFP transceiver on page 48 for more information.
•Removal and installation of a storage enclosure chassis
See Replacing a storage enclosure chassis on page 49 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 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.

AssuredSAN Ultra48 Series FRU Installation and Replacement Guide 19
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.
Attaching and removing the enclosure bezel
Before accessing front panel LEDs, you must first remove the enclosure bezel.
Figure 7 Partial assembly showing bezel alignment (2U48)
Attaching the enclosure bezel
1. Orient the bezel to align its back side with the front face of the enclosure as shown in the figures above.
2. Face the front of the enclosure, and while supporting the base of the bezel, position it such that the
mounting sleeves within the integrated ear caps align with the ball studs.
3. Gently push-fit the bezel onto the ball studs to attach the bezel to the front of the enclosure.
Removing the enclosure bezel
1. While facing the front of the enclosure, insert the index finger of each hand into the top of the
respective (left or right) pocket opening shown in the figures above.
2. Insert the middle finger of each hand into the bottom of the respective opening, with thumbs on the
bottom of the bezel face.
3. Gently pull the top of the bezel while applying slight inward pressure below, to release the bezel from
the ball studs.

20 Procedures
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 disk groups, 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
the SMC or RAIDar to record configuration settings before installing the new controller modules. See
Removing a controller module or expansion module on page 24, and Installing a controller module or
expansion module on page 26 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.
The two controller modules installed in the enclosure 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 disk groups has sufficient
time to stabilize (also see Verifying component operation on page 26).
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 the SMC, RAIDar, or the CLI to change the PFU setting.
