2. Pull the ends of both extraction levers outward simultaneously to release
the board from the centerplane receptacles.
See Figure 3-5 for the positioning of the levers.
3. If a board is not immediately replaced, a load board (Enterprise 6000
systems only) or a filler panel (Enterprise 4000 and 5000 systems only)
must be installed in its place.
See Section 3.2, “Filler Panels and Load Boards.”
3.4.2 Installing a Board
3.4.2.1 Board Slot Selection
Note – Logically there is no difference between the board slots in the front or
rear of the card cage, and each slot can accept any board type. It is suggested
that CPU/Memory boards be installed in the front slots, and I/O and disk
boards be installed in the rear slots because of cabling. Should the need arise,
however, any of these three board types can be placed in any of the numbered
board slots, with the exception of slot 1. Slot 1 should be used by the first I/O
board because it is the only slot connected to the onboard SCSI devices.
The first CPU/Memory board is placed in slot 0, followed sequentially by all
remaining even numbered slots. If there are boards remaining, they can be
installed sequentially in odd numbered slots, if available, in the system rear
(with the exception of slot 1 as noted above). See Figure 3-6 and Figure 3-7 for
board slot locations.
For CPU/Memory boards being placed in the rear of the system, ensure that
the component side is up. If the boards are placed in the front of the system,
ensure that the component side is down. See Figure 3-8.
