2. Ensure that both extraction levers are in the outward position as you slide the
board toward the centerplane receptacles.
The board will not seat fully unless the levers are in this starting position. See
on page 3-6 for positioning of the levers.

Caution – DO NOT FORCE any board into a slot; it can cause damage to the board
and system. The board should insert and seat smoothly. If it binds, remove the board
and inspect the card cage slot for any obvious obstructions. Also inspect both the
board and the centerplane for bent pins or other damage.
3. Push the board into the card cage, then simultaneously press both extraction
levers to seat the board on the centerplane.
Pushing both levers simultaneously avoids twisting the board and bending the
connector pins, and mates the board centerplane connector to the matching
receptacle on the centerplane. Do not press on board front panel to seat it—doing so
will damage the connector pins.
4. Mechanically lock the board to the system chassis by inserting a Phillips No. 1
screwdriver into each quarter-turn access slot and then turning to the locked
position.
See on page 3-6.

5. Once the board is installed, when the system is powered on, a message similar to
the following will be displayed on the monitor:
Example depicts screen output when a new CPU/Memory+ board has been hot-
plugged into slot 5 of an operating Enterprise system:
NOTICE: CPU Board Hotplugged into Slot 5
NOTICE: Board 5 is ready to remove
Additionally, any subsequent prtdiag(1M) output would include information for
board slot 5. Again, note that the system will not use the new board until the system
is rebooted.
Note – For new and existing Sun Enterprise 6x00, 5x00, 4x00, and 3x00 Systems that
have been configured to support dynamic reconfiguration, the system board can be
enabled into the current system using dynamic reconfiguration commands without
rebooting.
6. Reboot the system now or schedule a later time to reboot when system disruption
will be minimized.
