Checking the Power Cord Receptacle
Ensure that a qualified technician installed the correct power receptacle
accordingto siteplanningspecifications. ThenCray Research-trainedpersonnel
with the appropriate skills should use the following procedure to ensure that the
powerreceptacleisproperlywired.RefertoFigure 1fordrawingsofthe3-phase
power plugs and receptacles that are available for CRAY T3E AC cabinets.
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.
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. (Table 1 is based on a
wye-connected power source.)

Power Wiring for High-leakage Current
Please note the following statement by Underwriters Laboratories, Inc.
An insulated earthing conductor that is identical in size, insulation material, and
thickness to the earthed and unearthed branch-circuit supply conductors except
that it is green with or without one or more yellow stripes is to be installed as
partof thebranch circuitthat suppliestheunitorsystem. Theearthing conductor
described is to be connected to earth at the service equipment or, if supplied by
a separately derived system, at the supply transformer or motor-generator
(UL 60 95).
Unloading the Computer System Equipment
In most cases, if your loading dock is the same height as the transportation
vehicle, you may use pallet jacks to unload the system from the transportation
vehicle. Follow any instructions that are printed on the packing crates.
If the loading dock is not the same height as the vehicle, you must provide a
forklift or another approved method to unload the system. A platform or ramp
may be 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.

The shipping crates contain the mainframe, PC-10, system workstation,
additional system components, and system maintenance and user
documentation. After the system is unloaded from the truck, perform the
following steps before you transport and unpack it.
1. Ensure that the boxes arrived unopened. If any boxes are open, identify
and record the opened boxes through the CRUISE system.
2. Inspect the shipping crate for signs of external damage such as dents,
holes, crushed corners, and water marks. Record any signs of external
damage as an installation defect through the CRUISE system.

CRAY T3E AC System: Single-cabinet Installation Transporting the System to the Designated Location
HMM-164-0 Cray Research Proprietary 13
Transporting the System to the Designated Location
Use pallet jacks to move the system to its designated location. For the crate that
contains the CRAY T3E cabinet, use a regular-length pallet jack (positioned on
the side of the crate) to transport the cabinet. You may also use a long pallet jack
(approximately 60 in. [152 cm]) positioned on the end of the crate. If necessary,
you may use regular-length pallet jacks at each end of the crate to move the
cabinet a short distance. Follow any instructions that are printed on the crates.
Cray Research recommends that you leave each system cabinet in its shipping
crate until it reaches its final location. If the crate does not fit through the
planned access route, you may need to partially disassemble the crate.
The entire route to the computer room should meet the following requirements:
•Floor loading: maximum weight per cabinet is 1,640 lbs (744 kg)
•Minimum door height: 78.75 in. (2,000 mm)
•Minimum door width: 40.00 in. (1,016 mm)
•Maximum incline: 10 degrees (height:length = 1:6)
Refer to the appropriate installation documents for details on other equipment.
