Installing A Board - Sun Microsystems Enterprise 6500 Reference Manual

3.4.1.2 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 front panel) and then turn a quarter turn so that the
arrow points to the unlocked position (
2. Pull the ends of both extraction levers outward simultaneously to release the
board from the centerplane receptacles (
3. If a board is not immediately replaced, a load board (Enterprise 6500 systems
only) or a filler panel (Enterprise 4500 and 5500 systems only) must be installed in
its place.
See Section 3.2 "Filler Panels and Load Boards."

Installing a Board

3.4.2.1 Board Slot Selection
Note – 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 board slot,
with the exception of slot 1. Slot 1 should be used for an 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
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 (
