Installation and setup instructions

Use these instructions to install and set up your EXN4000 storage expansion unit.

Unpacking the EXN4000

Use these instructions to unpack the EXN4000.

About this task

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.

Procedure

1. Verify that the EXN4000 (2863-004) shipping packages include the following

items:

v1 EXN4000 storage expansion unit

v1 Enclosure shelf IDs label

vSmall Form Factor Pluggable (SFP) module (optional)

v1 IBM rail kit

v1 electrostatic discharge (ESD) wrist strap

v1 set of publications

v2 power cords

vMiscellaneous data cables, as ordered

CAUTION:

Use safe practices when lifting.

svc00168

32-55 kg (70.5-121.2 lbs)

CAUTION:

The weight of this part or unit is between 32 and 55 kg (70.5 and 121.2

lb). It takes three persons to safely lift this part or unit. (C010) 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 expansion unit and its tray using the handles built into the

cardboard tray. Place the expansion unit and tray on a table.

3. Remove the top portion of the plastic surrounding the expansion unit.

Installing the rails in an IBM 19-inch rack

Use these instructions to install the rails on which you will mount the EXN4000.

About this task

Note: Read this document in its entirety before proceeding.

Procedure

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

shown in Figure 3.

2. Refer to Figure 4 on page 3. At the front of the rack, position the right-hand rail

in 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.

Note: When installed, each EXN4000 will occupy a 3U space.
