3.5-Inch Fibre Channel Solid State Drive Product Manual Rev. 1.0
SINGLE CHANNEL MODE FOR EARLY REVISION DRIVES
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.
