The mating deskew time is minimum 250 msec.
A 10 K
Ω pull up register to 5V for each signal is asserted on the drive.
The open and ground states should be controlled as in Table 1.12.

(5) Parallel ESI
This signal is not supported in SFF8045 mode.
When receiving either Receive Diagnostic Result or Send Diagnostic Command,
the drive will assert this signal to initiate SFF-8067 Enclosure Discovery Phase
and to execute ESI operations.
the drive will assert this signal to initiate SFF-8067 Enclosure Discovery Phase
and to execute ESI operations.
(6) SEL_0, _1, _2, _3, _4, _5, _6
These seven SEL lines are provided for the binary value of the loop identifier by
the backplane.
the backplane.
This identifier is name AL_PA and is used for 126 unique value except 00h.
These ID signals are tested by the drive when powered on.
SEL_6 is the most significant bit and SEL_0 is the least significant bit.
Electric requirement for the signals is listed in Table 1.13.
These signals with high state have approximately 10K
Ω register on the
backplane.
