S INGLE C HANNEL M ODE FOR E ARLY R EVISION D RIVES
On early revisions of the drive, JP1 did not exist. These drives are identified by having a serial number
of “50” or less and only have an 8-way right-angled manufacturing connector. For this revision of
drive, the feature is enabled by setting bit 6 of the LOOP_ID to “1”. The LOOP_ID is set using the
SELECT_ID pins on the SCA-2 connector within the chassis to which the SSD is connected. See the
SEL_ID Function on page 30.
The SELECT_ID bits are normally configured by jumpers or a switch that allows the ID of the drive
to be set using the backplane of the SCA-2 connector. Table 39 lists the various configurations of the
SELECT_ID function.
