are two variations of the BA400-series rackmount kit:
¢

The BA400-CB lat is used with the HIA00 cabinet.

The BA400-CA It is used with the H9642 and H9646 cabinet.

NOTE: BA400-series chassis cannot be mounted in SAxxx storage array
cabinets.

introduction

The BA400-CB rackmount kit allows you to mount a BA400-gerieg chassis
in a H9A00 cabinet. The BA400—CA rackmount kit allows you tc mount a
BA400-series chassis in H9646 or H9642 cabinets.
NOTE: BA400-series chass!. cannot be mounted in SAxxx storage array
cabinets.
Installing @ BA400-series chassis requires the use of special mounting
hardware. Use the procedures in this manusal to install the mounting
hardware and to rack mount the chassis.
If you are rack mounting a system that is to be
shipped, you will be instructed at certain steps in
the procedure to refer to Appendix A for additional
procedures and hardware necessary to protect the chasais
during shipment.
Throughout this manual, the truck symbol is used to
indicate procedures or material required for shipping
rackmounted systems.

1 Verify Site Preparation
Before installing the rackmount kit*

Be sure the site and cabinet meet all environmental and power
requirements for the systems or expanders to be rack mounted. This
information is found in the system site preparation manual contained in

the Customer Hardware Information binder shipped with each system.
*

Be sure the cabinet has at least 25.5 inches of vertical space necessary
to accommodate the BA400-series chassis, the mounting brackets, and
required clearance space,
NOTE: Earlier BA400-series chassis may require more vertical space

due to limitations requiring specific rail-hole patterns for mounting
hardware. See Section 4.1.
*

Make sure the rackmount kit variation matches the cabinet type.
Figure 1 shows the two types of cabinet rails and their corresponding
rackmount kit number.

For previously installed systems, make sure the customer has backed
up the software and shut down the operating system.

4 Locate Mounting Hardware Positions
Three hole positions on the left and right vertical rails must be identified
before installing mounting hardware:

Upper isolator position

Lower igolator position

[-bracket position (top screw)

4.1 Determining Chassis Version (Eatly or Current)
Before using the foldout template at the back of this manual to locate
the three mounting hardware positions, you must check the BA400-series
chassis to determine if it is an early or current version.
Early versions of the chassis have only two cutouts at the bottom of the
front flanges (Figure 4). The current version has four cutouts at the bottom
of the front flanges.

4.2 Restrictions for Early Chassis Versions
The early chassis require that the upper-isolator position on the cabinet
vertical rails be restricted to those holes with a 1/2-inch space to the next
hole below. Figure 5 shows the repeating hole pattern and limited hole

positions for the upper isolator.

NOTE: Later versions of the chassis have no such restrictions for the upper
tsolator position.

4.3 Using the Template to Locate the Three Hole Positions
The foldout template at the back of this manual is a quick and easy tool
for locating the three mounting hardware positions. The template includes
required clearances at the top and bottom of the chassis.
NOTE: A minimum of 25.5 inches of vertical space is required for the
installation (this includes clearances and mounting hardware). Restrictions
on positioning early chassis may require additional space.

Find the foldout template at the back of the manual.

Prepare the template by folding it at the top where indicated.

Align the template with the holes on the front of the left vertical rail.
Mark the holes for the upper and lower isolators (Figure 6).

119

Use the template as follows:

Repeat step 3 for the right vertical rail.
NOTE: Remember that early versions of the chassis restrict upper
isolator positions to those holes with a 1/2-inch space to the hole below.
Also, early versions of the chassis have only two cutouts at the bottom
of the flange.

for shipping—skip this step.

CAUTION: Shipping a rackmounted BA400-series chassis without installing
tle rackmount shipping hardware will destroy the isolators and can seriously damage system components.
Six hole positions on the left and right vertical rails must be located before
mounting the shipping hardware. Use the template as follows to locate the
shipping hardware positions:
1.

Align the template with the holes on the front of the left vertical rail, as
in Section 4.3. Mark the holes for the upper and lower shipping locks.
Repeat this step for the right vertical rail.

Align the template with the holes on the inside of the left vertical rail,
as in Section 4.3.

NOTE: Be sure that the template is registered according to the upperisolator-hole position on the front of the vertical rail. Align the template
so that the upper isolator hole positions correspond.

9 Attach Skis to Bottom of Chassis
Attach the left and right ski assembly to the bottom of the chassis as follows
(refer to Figure 15):
1.

Place the chassis, back side down, on a sturdy table. Allow the bottom
of the chassis to overhang by an inch or vwo.
CAUTION: Handle the chassis with care to avoid damaging internal
components.

While attaching the left ski assembly to the chassis by clipping the ski
onto the front of the enclosure, slide the regulatory label plate between
the enclosure and ski assembly as shown in Figure 15.
Secure the sk as follows:
a.

Use the Phillips flat-head screw at the countersunk hole on the side
of the ski assembly (torque to 40 in - Ibf).

Use a hex screw and lock washer at the rear of the ski assembly
(torque to 40 in - Ibf).

Ensure that the red latch on the front of the ski assembly is securely
31

in place.

Attach the right ski assembly using the same procedure.

10 Install Chassis
Install the chassis as foliows (refer to Figure 16):
1.

One person should stand to the left of the chassis and one to the right.
Roth should lLift the chassis and slide it into the cabinet. The ski
assemblies should shide on top of the L-brackets.
Push the chassis in until the ski assemblies reach their stops on the
L-brackets.
WARNING: One person should hold the chassis in place, as it is unstable
in this position and will tip forward.

Using hex screws, lock washers, and flat washers, secure the chassis
(finger-tightened only) to the vpper and lower isolators on the vertical
rails.
Tighten the captive screw on each ski assembly.
Make certain that the chassis is centerad between the vertical rails and
that neither side of the chassis is touching the rails (Figure 17). You
can use a flat-blade screwdriver as a lever between the vertical rails
1]

and chassis flange.
Tighten the four hex serews (torque the hex screws to 10 1n - 1bf).

Loosen the screw and release the red latch on each ski assembly.
Tighten the screw so it will not fall out.

If you are preparing the cabinet for shipping, refer to Appendix A for
instructions on mounting the shipping hardware.

Appendix

Attaching Shipping Hardware
The design of the BA400-series rackmount hardware
requires the installation of special shipping hardware if
the cabinet is to be shipped. The shipping hardware locks
out the shock isolators and protects the isolators from the
rigors of shipping.

CAUTION: Shipping a rackmounted BA400-series chassis without installing the rackmount shipping hardware
will destroy the isolators and can seriously damage system components.

The shipping hardware consists of the following:

Upper and lower shipping locks for the left and right
vertical rails of the cabinet

Two ghipping plates, for the left and right side of the
chassis

Use the instructions in this appendix for installing the
shipping hardware.

A.1 Installing the Shipping Plates
Install the left and right shipping plates as follows (refer to Figure A-1):
1.

Attach one of the shipping plates to the side of the BA400 chaxsis using
four of the 3/8 long hex screws with captive lock washers (finger tight
only).
Secure the plates to the front and rear vertical rails using four more of
the same screws and four flat washers for each rail.
Repeat the procedure for the second shipping plate.
Torque all 24 shipping plate screws to 20 in - Ibf.

A.2 Installing the Shipping Locks
Install the upper and lower shipping locks as follows (refer to Figures A-2
and A-3):

Locate the four red shipping locks in the bag of shipping hardware.

Using the four 1-1/4 long hex screws, shipping locks, and flat washers,
secure the chassis to the vertical rails.

Figure A-2:

Shipping Locks

The shipping locks slide between the chassis flange and the vertical
rail and attach to the clip-on u-nuts installed in Step 5 of this manual
(torque the screws to 20 in - 1bf).
The shipping L.ardware must be removed before operating the system.

CAUTION: Operating a system with shipping hardware installed can
damage drives.
