Module Installation
NOTE:
If the PEM jumpers became loose during shipping or handling, refer
to FN 2302, CRAY T3E PEM Jumper Positions and Definitions, for
replacement information.
1.
If necessary, transfer daughter cards to the module. Refer to
2.
Insert the replacement module in the rails:
a. Position the replacement module with the heat sink to your right, the
connector blades toward the ground, and the handle toward your chest.
b. Align the module assembly with the module rails; then, with even
pressure, partially insert the module into the rails.
c. When the module handle is near the lower mechanical interlock, rotate
the interlock until the slot aligns with the module handle.
d. Partially insert the handle into the lower mechanical interlock, then
release the lower interlock. Now rotate the upper interlock until the
slot aligns with the module handle.
e. Fully insert the module, then release the upper interlock. Press firmly
to ensure a good connection of module and power supply.
3.
Install the retaining screw (setscrew) in the bottom of the module handle
and tighten it with a 3-mm hex wrench until the module is secured to the
rail.
The retaining screw helps ensure that the modules are installed to a
uniform depth in the module box (card cage), and it protects the module
and module connectors against damage related to movement.
4.
Cam the module and insert plastic shuttle locks. Refer again to
if necessary.
CAUTION
Observe all ESD precautions. Failure to
do so could result in damage to the
equipment.
