Carrier-Grade Enclosure
installation instructions

This document provides specific information regarding
the carrier-grade versions of the HP StorageWorks
Dual I/O 2.5" DC-power Drive Enclosure.

This section provides cabling information for installing the HP
StorageWorks Dual I/O 2.5" DC-power Drive Enclosure.

NOTE:

This carrier-grade product is intended for use in both common
bonding networks and isolated bonding networks.

NEBS chassis ground

There are two grounding methods that can be used when installing the
HP StorageWorks Dual I/O 2.5" DC-power Drive Enclosure:

• Using a single wire coming from the front of the chassis ears

• Using a cable from the power supply

Installation and grounding instructions — single wire method

1. Attach the rear brackets to the Carrier-Grade Enclosure.

2. Attach the left bracket assembly to the left rack rail.

3. Attach the right bracket assembly to the right rack rail.

4. Insert cage nuts into the rack holes.

5. Align the Carrier-Grade Enclosure with the rails, and then slide it

into the rack until the ears of the enclosure are about 1 to 2 inches
from the rack front rails.

6. Attach a flat washer between the right mounting ear (bottom hole)

and the rack, and then loosely attach the bracket to the rear bracket
assemblies.

5. Ground cable lug. Position between ear and rail (cable not

shown).

8. Loosely attach the rear brackets to the rear bracket assemblies.

.

1. Verify that both power switches are off.

2. Check the DC cable part numbers and wire labels carefully before

connecting the cable to the source.

IMPORTANT:

One wire is labeled as ground; the other two are
labeled as positive and negative.

3. Connect a DC power cable to the first power-and-cooling module,

using the D-shell connector. Use the up arrow on the shell to ensure
proper positioning before tightening.

9. Attach the loose end of the ground cable to the front rack ground

rail.

10. Verify that the Carrier-Grade Enclosure is evenly spaced between

the right and left rack rails, and then tighten the front and rear
bracket screws.

Installation and grounding instructions — power supply cable
method

Two DC power cables are packaged with each disk enclosure. Use only
the DC power cables provided.

Site wiring must include an earth ground connection to the DC power
source. Grounding must comply with local, national, or other applicable
government codes and regulations.

4. Tighten the screws at the top and bottom of the shell with a torque

between 1.7 N-m (15 lb-in) and 2.3 N-m (20 lb-in) to attach the
cable securely to the power-and-cooling module.

5. Securely connect the other end of the DC power cable to a DC

power source.

CAUTION:

If the enclosure is connected to DC power sources that
are not within the designated –48V DC nominal (–36
VDC to –72 VDC) range, it might be damaged.

6. Connect the wire labeled Ground to an appropriate earth ground.

7. Using the instructions above, connect the second DC power cable

to the other power-and cooling-module and to a DC power source.
If one power-and-cooling module fails, the second power-and-cooling
module automatically takes the full load.

8. Power on the system as described in the following section.

Gigabit Ethernet port cabling

Gigabit Ethernet Ports (intra-building ports) of the HP StorageWorks
Carrier-Grade Enclosure require the use of shielded Ethernet cables
grounded at both ends. Furthermore, please note the following:
