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
• AssuredSAN Ultra48 Series CLI Reference Guide
Intended audience
This guide is intended for storage system administrators.

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.
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.
