Setting the SCSI Bus Address - CFP2107S
There are three jumpers available for configuration of the SCSI ID: E1, E2, and
E3.
An optional 2mm pin pitch right angle header is located on the front of the
PCBA (opposite the SCSI interface connector) which allows changing the SCSI
IDs while the drive is mounted in the system. The header includes three pins,
0E1, 0E2 and 0E3 which can alternatively be used to select the SCSI Bus
address. This connector may also be used to cable the SCSI ID select to a remote
switch. A receptacle connector Amp P/N 111622-1 or equivalent can be used to
connect a ribbon cable to this header.
Table 4-6 defines the relationship between the jumpers and the SCSI ID:

Low and Out = Open or TTL High. The odd numbered pins (lower
row) are grounded and the even numbered pins carry the signal.
