Board Slot Selection

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 Figure 3-5 and Figure 3-6 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 (Figure 3-7).
