Setting the SCSI Bus Address - CFP2107W
There are four jumpers available for configuration of the SCSI ID: E1, E2, E3
and E4.
The 68-pin unified connector includes a standard 2mm pitch auxiliary header
which includes pins to allow remote selection of SCSI IDs. A receptacle
connector Amp P/N 1-111623-7 or equivalent can be used to connect a ribbon
cable to this header.
Table 4-11 defines the relationship between the jumpers or the pins on J5 and
the SCSI ID:

TTL logic low or logic ground. The odd numbered pins (lower row)
are grounded and the even numbered pins carry the signal.
