Site Wiring and Power Considerations
The cabinet’s AC distribution boxes use common industrial wiring. Consider the following
site wiring and power source requirements:
AC power source. The AC power source must provide the correct voltage, current, and
•
frequency specified on the manufacturer’s name plate.
Earth ground. You must have an earth grounding conductor to the cabinet’s power
•
receptacles.
Circuit overloading. Make sure the power circuits and associated circuit breakers
•
provide sufficient power and overload protection. To prevent possible damage to the
AC distribution boxes and other components in the cabinet, isolate its power source
from large switching loads (such as air conditioning motors, elevator motors, and
factory loads).
Module power distribution. There are two accessory outlets inside the cabinet for
•
module power distribution. All units attached to these outlets must be auto-ranging
between 180 through 257 VAC, 50-60 Hz.
Power Interruptions. The 72-inch cabinet and its modules will withstand the following
•
applied voltage interruptions (with or without an integrated UPS):
Input transient: 50% of nominal voltage
•
Duration: one half cycle
•
Maximum frequency: once every ten seconds
•
Power Failures. After total power failure, the modules within the cabinet will
•
automatically perform a power-up recovery without operator intervention, once power
is restored.

Unpacking and Moving the Cabinet
WARNING Risk of bodily injury! The cabinet can weigh up to 636 kg (1420 lb) fully
loaded. Do not attempt to move the cabinet without a forklift or sufficient
help from others. Always push the cabinet from the front to prevent it
from tipping over (Figure 10). If you need to move the cabinet up or down
a ramp (with or without a forklift), remove drive modules from the upper
half of the cabinet to improve stability.
CAUTION If you receive the cabinet and modules in extremely cold weather (below
The shipping crate provides built-in ramps and instructions for rolling the cabinet off of
the skid without the use of a forklift. Some models have a removable stability foot that
prevents the cabinet from tipping over when it is moved. You must attach the stability foot
to the front of the cabinet (at the bottom) before you move the cabinet. Figure 8 on page 17
shows the unpacking instructions included on the front side of the shipping crate for

Installing the Cabinet
The installation tasks you must perform depends on how you ordered the 72-inch cabinet
and its associated modules. In most cases, you will need to do some or all of the following:
1 Check the shipping contents list to make sure all equipment arrived at the site.
2 Move the cabinet to its final location. Once it is in position, lower the levelling glides
and level the unit as necessary.
3 Install all applicable host, host adapter boards, hubs, switches, and other devices on the
network. Route the appropriate interface cables to the cabinet.
4 Route the main power cords from the cabinet to the external power source (but do not
plug in yet).
5 If necessary, install applicable mounting hardware for rackmount units. Refer to kit
instructions.
6 Install all devices in cabinet (command modules, drive modules, etc.) Refer to
applicable installation instructions for each device.
7 Route and connect appropriate interface and power cables to devices in cabinet.
8 Plug in main power cord to cabinet and turn on power. Make sure that you power-up
all devices in the proper sequence.
9 Test all devices in the cabinet and on the SCSI bus or Fibre Channel network for error
free operation.
10 Install software and configure the drive modules and controller modules as necessary.
For installation and operation information on individual modules , software, or other
network components, refer to the user manuals shipped with each unit.

Transportation Instructions
WARNING Risk of bodily harm. Failure to follow this procedure could result in a
cabinet becoming very unstable up/down inclines or over uneven surfaces.
To maximize stability during the transportation of a 72-inch cabinet, the center of gravity
for the cabinet must be as close to the base as possible. For this reason, it is recommended
that you transport the unit with the upper half of the modules depopulated. All heavier
weighted components in the upper half of the cabinet should be taken out and transported
by static protective means. This includes drives, battery canisters, and controllers.
It is not necessary to remove components in the rear of the modules, such as power
supplies. These components will not disturb an optimal center of gravity. If the original
shipping boxes are available, these may serve as ideal transportation for these components.
Here are some guidelines to follow:
Make note of the Tray ID settings for the drive modules. It is imperative that the drives
•
be replaced in the exact slots from which they were removed. Make sure the drives are
in the same order during shipping and that the drives have been associated with the
proper Tray ID.
If any cables need to be disconnected, note the cable configuration for future assembly.
•
The module’s user guide will help by providing cabling diagrams.
Keep all components from the same modules together.
•
All components must be replaced to the same module and location. This will avoid
•
conflicts and data loss.
