AssuredSAN 4004 Series FRU Installation and Replacement Guide 7
About this guide
Overview
This guide identifies 4004 Series FRUs (field-replaceable units) used in 2U12 and 2U24 chassis form
factors, and describes how to remove or install them within the AssuredSAN™ 4004 Series storage
enclosure products listed below:
•CNC (Converged Network Controller) Controller enclosure (4824/4834 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: 4524/4534
For a complete description of product models, see the “Components” chapter within the Setup Guide.
AssuredSAN 4004 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 controller enclosures support compatible Dot Hill drive enclosures for adding storage.
Supported enclosure form factors include traditional 2U models (2U12 and 2U24) and high-capacity
models in 2U (2U48) and 4U (4U56) format. A summary overview of drive enclosures supported by
controller enclosures is provided in the “Connecting the controller enclosure and drive enclosures” topic
within the AssuredSAN 4004 Series Setup Guide.
AssuredSAN 4004 Series enclosure user interfaces
The 4004 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 4004 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), 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.
See Dot Hill’s products: http://www.dothill.com/products page for the latest product information. See the
customer resource center (CRC) site for interoperability information: https://crc.dothill.com.

20 Procedures
2 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 8 for a list of these documents and where to find them online.
IMPORTANT: Procedures pertain to FRUs used in 4004 Series (2U24 and 2U12) products. Procedures
pertaining to FRUs used in 2U48 and 4U56 chassis are addressed in Ultra48 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.
