Installation and setup instructions

Use these instructions to install and set up your EXN3200 storage expansion unit.

Unpacking the EXN3200

Use these instructions to unpack the EXN3200.

Important: If your system was shipped already assembled and cabled in a rack, go directly to the

Installation and Setup Instructions for your N series storage system.

Note: The contents of the box might differ based on the model you purchased.

1. Verify that the EXN3200 (2857-306) shipping packages include the following items:

v1 EXN3200 storage expansion unit

v1 IBM rail kit

v1 electrostatic discharge (ESD) wrist strap

v1 set of publications

v4 power cords

vMiscellaneous data cables, as ordered

vDisk carriers, as ordered

CAUTION:

Use safe practices when lifting.

LIFTING HAZARD

CAUTION

To reduce the weight of a disk shelf to

approximately 53 lbs (24 kg), remove

all the IOMs and power supplies

before lifting.

A disk shelf containing the two IOMs,

four power supplies, and four disk

carriers weighs 82 lbs (37 kg).

exn30006

CAUTION:

An EXN3200 containing two IOMs, four power supplies, and four disk carriers weighs 37

kg (82 lbs). Use two people to lift an EXN3200 into a rack. To make the unit lighter and

easier to move, remove the power supplies and Input/Output Modules (IOMs), noting the

location of each component for reinstallation. Do not remove the disk drives or drive

blank covers to reduce the weight. After the unit is installed in the rack, reinsert the

power supplies and IOMs.

2. Remove the EXN3200 from the carton using the integrated handles built into the sides of the unit.

Place the unit on a table.

Installing the rails in an IBM 19-inch rack

Use these instructions to install the rails on which you will mount the EXN3200.

Note: Read this document in its entirety before proceeding.

1. Loosen (but do not remove) the four rail adjustment screws on each rail.

2. Use Figure 5 on page 3 for reference. At the front of the rack, position the right-hand rail into the rack

at the appropriate EIA location (make sure that the two locating pins seat properly). The bottom of

the rail should line up with the bottom EIA boundary.
