DANGER: Expansion units are extremely heavy. To avoid injuring yourself

or damaging an expansion unit, you must work with at least two other

people when you install an expansion unit in the rack. Do not remove the

disk drives to reduce the weight.

Caution: Use safe practices when lifting.

Use the figure on the next page 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.

When installed, each EXN2000 unit will occupy a 3U space.

Using two silver pan head M5 screws, attach the rail to the front of the rack

using holes H3 and H7. T

Note:

ighten these screws with a screwdriver.

2.3 At the rear of the rack, position the rail at the same EIA location used in

step 2.2 (make sure that the locating pins seat properly). Using two silver

attach the rail to the rack using holes H2 and H8.

2.4 Tighten the four rail adjustment screws on the installed rail.

2.5 Repeat steps 2.2 through 2.4 for the left-hand rail.

32 kg (70.5 lb)

Caution: Use safe practices when lifting.

DANGER: Expansion units are extremely heavy. To avoid injuring yourself

or damaging an expansion unit, you must work with at least two other

people when you install an expansion unit in the rack. Do not remove the

disk drives to reduce the weight.

Note: Verify the shelf IDs before installing into the rack. All shelf IDs should

be correct and sequential in the individual loop(s). If the filer and expansion

unit were configured together by manufacturing, these IDs are already set.

The label on the front should match the switch on the back. For more

information, refer to the .EXN2000 Hardware and Service Guide

At the front of the rack, using four black hex head M5 screws in the H2

and H8 holes, secure the system unit to the rack by threading the screws

through the system unit bracket and the rack frame rail into the threaded

rail nuts. Tighten the screws using the 7mm nut driver.

3.3 From the rear of the rack, use two silver pan head M5 screws to attach

the rear of the chassis to the rails as shown below.

Screws

4.1 Make sure that all expansion unit speed switches are set to the correct

position for your application.

For example, if connecting to an N3700 storage system, the speed switch

must be set to the 1Gb position. If connecting to an N5000 series or an

N7000 series storage system, the speed switch must be set to the 2Gb

position.

5Grounding expansion units

5.1 If only one expansion unit is being used, go to Step 6, "Installing the

power cables" on page 9.

If two or more expansion units are being used continue with the

following.

Using the grounding kit, fasten the lug, fasten the lug at one end of the

0.25m grounding cable to one of the two threaded inserts (adjacent to

the power supply receptacles as indicated by a ground symbol) at the

back of the expansion unit using the M5 x 0.5-inch screw.

If additional expansion units need to be grounded, continue attaching

the grounding cables from unit to unit, overlaying the hole on one end

of the grounding cable from one to the next.

Note: For proper grounding, you must fasten your expansion unit(s)

together. Use the provided braided copper grounding cables and screws

(may be in the rail kit).
