Features
The DS2500 disk enclosure provides:
• Redundant power supplies and blowers
• FC disk drives that can be added or replaced with the system on (although the affected file
• Environmental services sensors that monitor the disk enclosure and provide real-time error
• High-availability to minimize unplanned downtime
• Customer-replaceable components
Each DS2500 is connected to Host Bus Adapters (HBAs) through two independent Fibre Channel
Arbitrated Loop (FC-AL) buses, also known as loops, to provide no single point of failure (NSPOF). Each
disk drive connects to loop A through I/O module A, and to loop B through I/O module B. Figure 1
shows the maximum configuration of four DS2500s.
The disk enclosure supports high-availability requirements through the following features:
• Hot-pluggable components
• High-capacity, high-speed disks
• Redundant, customer replaceable power supplies and blowers
• Redundant I/O modules
• Support for mirrored disks in the HP-UX environment
• Online firmware upgrades
• Hardware event monitoring and real-time error reporting

Whenever the EMU detects a condition that could affect operation, it performs the following operations:
• Generates an audible alarm
• Displays status in visual indicators
• Generates an error condition report
• Reports the condition to the HP-UX application software

Figure 3 identifies the EMU displays, controls, and connectors.
Figure 3 EMU controls and displays
1. Status indicators:
a. EMU heartbeat—Flashing green signifies an operational EMU
b. DS2500 power—Solid green signifies that the +5 VDC and +12 VDC signals are within
c. DS2500 fault—Solid amber indicates that an enclosure error condition exists (normally off)
2. Alphanumeric display—A two-character display of the enclosure functions and status (typically
displays the enclosure ID).
3. Function select push button and back light—Enables you to specify what information appears
in the alphanumeric display. Pressing and releasing, or tapping the function select button
allows you to sequence through the different sublevels of a display group. The back light is
on when an error condition exists.

I/O modules
TwoI/Omodulesprovideaninterfacebetweenthedisksandthehostsystem. TheI/Omodulesareused
to route data to and from the disks in a dual-loop configuration to eliminate a single point of failure.
Each disk drive is connected to both I/O module A and I/O module B (Figure 4-3). Each I/O module is
connected to an independent, external FC loop. I/O module A connects to loop A, and I/O module B
connects to
CAUTION:
Keep the loops completely separate to ensure that the failure of a single component (I/O module,
transceiver, or cable) does not stop data transmissions to active drives.

The operation and function of both I/O modules are identical. Each I/O module has two ports that
can transmit and receive data for bidirectional operation. Port use and connections are configuration
dependent (see "Cables and cabling" on page 24). Each port is identified with a transceiver element
number,anditsstatusisdisplayedonanLED(Figure 5). Port 1 is the bottom loop port, and port

• Port 2 LED—On indicates that a signal was detected at the top transceiver.

The power supply circuitry monitors input voltage, current, and temperature. If it detects an unacceptable
level of any of these elements, the status indicator turns off and an error is reported to the EMU.
The EMU uses the temperature sensor signal to adjust the speed of the blowers. If one blower fails or
spins at a reduced speed, the speed of the other blower increases to provide adequate air flow.

Power supply and blower status indicator
A green LED on the blower (Figure 6-2) indicates the operational status of the power supply and the
blower. If either component fails, the LED turns off and an error alarm sounds. The failing component
should be replaced as soon as possible.

Preparing to install a DS2500
Before installing the DS2500:
• Ensure that
• Ensure that the supported HP-UX operating software is installed on the host. See "System
requirements" on page 15 for the minimum version of supported software.
• If you are adding to an existing storage system, ensure that the existing storage system is
operating properly before proceeding.
• Locate a N

o. 2 Phillips screwdriver.
WARNING!
A DS2500 with all components installed weighs more than 29.5 kg (65 lb.) and requires a minimum of
two people to move. To safely and easily install the DS2500, using antistatic protection remove the
drive blanks, power supply/blower assemblies, EMU, and I/O modules. This reduces the weight of
the DS2500 to approximately 11.0 kg (24 lb). Even though a single person can lift this weight, the
DS2500 is difficult to install because of its physical size. Therefore, HP recommends that a minimum of
two peop
le install an empty DS2500 in a rack.
Unpacking the shipping carton
Inspect the contents of the shipping carton. If anything is missing or appears damaged, contact an
HP sales representative.
The carton contains:
• DS2500 disk enclosure with disk blanks, I/O modules, EMU, and power supply/blower
assemblies
• Two power cords
• FC SFPs
• HP StorageWorks 2500 Disk System read me first document
• Snap-in rail kit
• Eight round-hole conversion pins
• Rack template

You can identify the left and right rack rails by the markings (L) and (R) stamped into the sheet metal.
NOTE:
The rail kit contains adapter brackets that are used when mounting some devices in the rails; however
these brackets are not used when mounting a DS2500.

Installation
Converting the rails for round-hole racks
By default, the rack rails are configured for square-hole racks with load-bearing pins designed to
fit through the U-holes.
• If you are installing the disk enclosure in a square-hole rack, skip this section and continue with
"Installing the rails"onpage27.Donotremovethepinsfromtheendsoftherails.
• If you are in
stalling the disk enclosure in a round-hole rack, you must convert the rails as follows:

1. Locate the b
ag of miscellaneous hardware that is shipped with the rack rails.
2. Locate the eight round-hole pins.
3. Use a No. 2 Phillips screwdriver to remove the standard pins from the front and back ends of a rail.
4. Install four round-hole pins into the rail (Figure 11).
5. Repeat st
eps 3 and 4 on the other rail.

2. Insert the front of the rail into the inside front column of the rack, making sure that the pins extend
