Installing A Board - Sun Microsystems Enterprise 6500 Reference Manual

5.5.1.2 Removing a Board from a Powered-Off System
1. Use a Phillips #1 screwdriver to mechanically release the board from the system
card cage.
Insert the screwdriver into each quarter-turn access slot (the slots are located on the
left and right sides of the board's front panel) and then turn a quarter turn so that
the arrow points to the unlocked position (
2. Unfasten any cable connectors from the front panel and set them aside.
Label cables to identify them for reconnection later.
3. Pull the ends of both extraction levers outward simultaneously to unseat the
board from the centerplane receptacles.

Installing a Board

5.5.2.1 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 these
exceptions:
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.
Slots 14 and 15: In Enterprise 6500 systems, Disk boards are supported only in these
two slots.
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
Other than the slot 1 exception, a Disk board can be placed in any of the numbered
board slots in Enterprise 5500/4500 systems. Use only slot 14 and slot 15 in
Enterprise 6500 systems, and you must use slot 15 if only one Disk board is installed.
For 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 (
