A.1.2 SuperSPARC module
When installing or replacing a SuperSPARC module, use the following
guidelines to verify that you have selected a valid location.
Warning – The heatsinks on the SuperSPARC module may be hot. Use caution
when removing or installing SuperSPARC modules and avoid contact with the
heatsinks. Hold SuperSPARC modules only by the edges.
Each system board has two SuperSPARC module connectors, designated A and
B (location A is closest to the backplane connector). See Figure A-1. The
modules mount above the system board on standoffs. Modules should first be
installed in the A connectors on consecutive system boards starting with the
system board in slot 0. After all of the A connectors are filled, begin filling the
B connectors, starting with the system board in slot 0 and working down.
