Overview
These installation procedures are intended to assist Cray Research personnel
with the mechanical installation of 2 or more CRAY T3E air-cooled (AC)
cabinets. The installation includes the following tasks:
•Unpacking and positioning the system components
•Connecting cables
•Powering on the system and verifying operation
•Verifying system function with diagnostics
This document provides an efficient sequence for the installation. You may
deviate from the sequence as required; however, when possible, perform the
procedures in the order shown.
Cray Research ships CRAY T3E AC cabinets in three shipping configurations:
1 cabinet per shipping crate, 2 cabinets per crate, and 3 cabinets per crate. When
a crate contains 2 or 3 cabinets, the cabinets are bolted together and the wires
that pass between cabinets are connected.
As a result of these variable shipping configurations, you may not be required
to complete internal cabinet wiring. For example:
•If your system contains 2 or 3 cabinets, and the cabinets are bolted
together during shipment, then you do not need to complete internal
cabinet wiring.
•If your system contains 4 or more cabinets, or if you must otherwise bolt
cabinets together, then you must complete internal cabinet wiring.
Your system configuration and site access restrictions determine how your
system ships.
NOTE: This document uses the term prejoined to refer to cabinets that are
bolted together during shipment.
This document does not contain troubleshooting procedures, nor does it contain

•Verify that all electrical services meet site planning specifications.
•Verify that the air-conditioning equipment meets site planning
specifications.
•Verify that the ground clamps (for grounding the cabinets to the floor
grid) are in the correct locations (near the floor cutouts for I/O cables).
Checking the Power Cord Receptacles
Ensure that a qualified electrician installed the correct power receptacles
accordingto siteplanning specifications.Then CrayResearch-trainedpersonnel
should use the following procedure to ensure that the power receptacles are
properly wired. Refer to Figure 1 for drawings of the 3-phase power plugs and
receptacles that are available for CRAY T3E AC cabinets.
Performthefollowingprocedureforeachpowercordreceptaclethatwillsupport
a CRAY T3E AC cabinet:
1. Turn off, lock, and tag the customer’s circuit breaker(s) that control power
for the CRAY T3E AC cabinet power receptacle before you perform
Step 2 and Step 3.
2. Set the multimeter to a low-resistance setting.
3. Measure between the power receptacle ground-post hole and an
appropriate earth-ground location and ensure that resistance is less than
1 ohm. Figure 1 shows the post hole locations. (Appropriate earth-ground
locations could include the floor grid, a metal case receptacle, and a
circuit breaker shell.)
4. Remove the lock and tag and restore power through the customer’s circuit
breaker(s).
5. Set the multimeter to a high AC-voltage range.
DANGER
Ensure that the electrical circuit
breakers for the power receptacle being
checked are off, locked, and tagged.
Failure to do so could result in severe
shock and burns.

6. Measure between the ground-post hole and an appropriate earth-ground
location. If you detect voltage on the ground-post hole, contact a
site-approved electrician. Do not proceed with the installation.
NOTE: The ground wire may act as an antenna and, through
impedance, generate a low voltage (usually less than 1 Vac).
This is normal.
7. Perform voltage checks between the posts listed in Table 1. Refer again to
Figure 1, which shows the post locations.

CRAY T3E AC Multiple-cabinet Installation Unloading the Computer System
HMM-369-0 Cray Research Proprietary 17
Unloading the Computer System
Cray Research ships CRAY T3E AC cabinets in three shipping configurations:
1 cabinet per shipping crate, 2 cabinets per crate, and 3 cabinets per crate. Your
configuration and site access restrictions determine how your system ships.
If your system includes 1 or more cabinets that ship singly (1 cabinet per crate),
the side panels are installed on the single cabinet(s). If your system does not
include a cabinet that ships singly, then the side panels ship in separate boxes.
Figure 2 shows the CRAY T3E AC single-cabinet shipping configuration, lift
openings, and dimensions. Figure 3 shows the CRAY T3E AC 3-cabinet
shipping configuration, lift openings, and dimensions. The 2-cabinet shipping
configuration is a smaller version of the 3-cabinet configuration.
In most cases, if your loading dock is the same height as the transportation
vehicle, you may use ROL-A-LIFTs or pallet jacks to unload the system from
the transportation vehicle. Specifically, you may use a pallet jack to unload a
shipping crate that contains only 1 cabinet, and you must use ROL-A-LIFTs to
unload shipping crates that contains 2 or 3 cabinets.
When you use ROL-A-LIFTs, position the ROL-A-LIFTs on the ends of the
shippingcrateas shown in Figure 3.Ensurethat you place aboardbetween each
ROL-A-LIFT and the side of the shipping crate as shown in Figure 3; position
theboard 35 to40 in.(889to 1,016mm)from thetopof theshipping crate. (Two
2 in. x4 in. boards are supplied with each crate that contains 2 or 3 cabinets; the
boards are strapped to the outside of the crate.)
NOTE: You will use the ROL-A-LIFTs when you unpack crates that
contain 2 or 3 cabinets.
If the loading dock is not level with the vehicle, you must provide a forklift or
anotherapprovedmethod to unload thesystem.A platform or rampmaybe used
to obtain the desired level as long as the ramp does not exceed a ratio of 1 unit
vertical to 6 units horizontal. Refer to Preparing for a CRAY T3E Air-cooled
System Installation, publication HR-04118, for more information on site
requirements.
CAUTION
Prevent computer equipment from
rolling off the transportation vehicle.
Failure to do so could result in serious
damage to the computer equipment.
