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.

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.
2.6 Repeat steps 2.1 through 2.5 if installing a second EXN2000.

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.

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).

Installing the power cables

6.1 Make sure all power supply switches of the expansion unit(s) are in the
Off position.
6.2 Connect the power cords to all PSU1 and PSU2 power receptacles for all
expansion units that are being installed by holding the wire clamp up,
plugging in the power cord, and lowering the clamp to secure the power
cord.
6.3 Connect the power cords to the power sources, making sure that the
power supplies on the left side of the system are connected to a separate
AC source than the power supplies on the right side of the system. This
ensures redundant power.
Do not power on the system at this time.

7Cabling the EXN2000

7.1 Cable the first expansion unit (for example, ID=x=1) controller A Output
port module to the second expansion unit ( ID=x+1=2)
controller A module Input port. Repeat as necessary to attach a third
expansion unit ( ID=x+2=3) to the second expansion unit.
For dual node connection, cable the expansion unit controller B Output
port module to the expansion unit controller B module Input port. Repeat
as needed.
Make sure that the cables are secure.

Notes:
1. To cable your expansion unit to an N series storage system, refer to the
for the N series storage system to
which you are connecting the EXN2000.
2. For information about dual-path Fibre Channel cabling, refer to the
for the N series storage system to
which you are connecting the EXN2000.
