3.4.4.1 Removing a Module
Each module is locked to the main board with a single standoff and is connected to
the main board by two connectors. The pins within the connectors are compressed to
the corresponding board mating surfaces by a metal compression bar which, when
secured with screws, compresses the module connector pins to the board mating
surfaces (

).

1. Use the procedures in Section 3.4.1 “Removing a Board,” to remove the applicable
CPU/ board.
Hot Surface –
The heatsinks on the UltraSPARC II modules may be hot. Use
caution when removing or installing UltraSPARC II modules and avoid contact.
2. Use a 3/32 Hex driver to loosen all screws on each of the compression connectors
on the module to be removed (three screws for the 288-pin connector, two screws
for the 144-pin connector) (
