x System Storage EXP2512 and EXP2524: Installation and Maintenance Guide
Chapter 1. Introduction
This Installation, User’s, and Maintenance Guide contains instructions for setting up
your IBM System Storage
®
EXP2512 Express Storage™Enclosure and IBM System
Storage EXP2524 Express Storage Enclosure and provides the instructions for
replacing components. The IBM System Storage EXP2512 and IBM System
Storage EXP2524 are referred to in this document as the EXP2500, unless
specified otherwise.
This document contains information about:
v Setting up and cabling the EXP2500
v Starting and configuring the EXP2500
v Replacing components
v Solving problems
The EXP2500 provides high-capacity, Serial Attached SCSI (SAS), nearline SAS, or
Solid State disk storage. The EXP2512 supports up to 12 SAS or nearline SAS
hard disk drives and the EXP2524 supports up to 24 SAS, nearline SAS, or Solid
State hard disk drives. The EXP2500 delivers fast, high-volume data transfer,
retrieval, and storage functions among multiple drives. The EXP2500 is designed
for continuous, reliable service; the modular, redundant hard disk drives and power
supplies (with fans) use hot-swap technology for easy replacement without turning
off the EXP2500.
The EXP2500 comes with two 800-watt ac power supplies, one environmental
services module (ESM), a filler panel to cover the empty ESM bay, and 12 or 24
drive filler panels, depending on the storage enclosure model. The drive filler panels
can be replaced with optional hard disk drives.
If firmware and documentation updates are available, you can download them from
the IBM support website. The EXP2500 might have features that are not described
in the documentation that comes with the unit, and the documentation might be
updated occasionally to include information about those features, or technical
updates might be available to provide additional information that is not included in
the EXP2500 documentation.
Note: Changes are made periodically to the IBM website. Procedures for locating
firmware and documentation might vary slightly from what is described in this
document.
To check for updates, go to http://www.ibm.com/systems/support/. For firmware
updates, click Downloads. For documentation updates, click Documentation.
The EXP2500 comes with a limited warranty. For more information about the terms
of your warranty, see the Warranty and Support Information document that comes
with the EXP2500.

6 System Storage EXP2512 and EXP2524: Installation and Maintenance Guide
What the EXP2500 offers
The EXP2500 provides several features for easy operation, including the following
features:
v Customer replaceable units (CRUs)
The major CRUs in the EXP2500 are SAS, nearline SAS, or Solid State hard
disk drives, ESMs, and power supplies. See “Replaceable EXP2500
components” on page 25.
v Fault indicators
All CRUs have fault or status light emitting diodes (LEDs) to indicate hardware
failures.
v Redundant cooling and power capabilities
The EXP2500 uses a dual ac input power system. The redundant cooling of the
fans enables continued operation if up to three fans fail. The EXP2500 comes
with two 800-watt hot-swap power supplies, which provide redundant power for
all EXP2500 configurations. If a problem occurs with one of the power supplies,
the other power supply can meet the power requirements.
Major components of the EXP2500
Orange on a component or label indicates that the component can be hot-swapped.
You can install or remove a hot-swap component while the EXP2500 is running. For
information about installing hot-swap components, see Chapter 4, “Parts listing,
EXP2512 and EXP2524 expansion enclosures,” on page 25.
Blue on components and labels indicates touch points, where you can grip a
component, move a latch, and so on.
The following illustrations show the major components of the EXP2512 and
EXP2524.

© Copyright IBM Corp. 2010, 2011 9
Installing hot-swap hard disk drives
The EXP2512 supports up to 12 IBM SAS or nearline SAS hard disk drives. The
EXP2524 supports up to 24 IBM SAS, nearline SAS, and Solid State hard disk
drives.
Each drive comes preinstalled in a drive tray, ready for installation in the EXP2500.
(Do not detach the drive from the tray.) Be sure to record the location information
for each drive in Table 2 on page 2.
The EXP2500 comes with filler panels in the drive bays. Before you install a new
hard disk drive, remove the filler panel and save it for future use. Each of the drive
bays must contain either a filler panel or a hard disk drive.
To install a hard disk drive in the EXP2500, complete the following steps. You can
install drives while the EXP2500 is turned on.
1. Read the instructions that come with the hard disk drive.
2. Read the safety information that begins on page iii and “Installation guidelines”
on page 29.
3. Remove the filler panel from the bay into which you want to install the hard disk
drive:
a. Insert a finger into the square hole on the left side of the filler panel to grip
and pull the filler panel out of the drive bay.
b. Save the filler panel for future use.
