Which bit of the high byte of the SCSI data bus
will the LSI53C040 see as bit SCSI High ID 1
Enter a number between
8
and
15
.
Which bit of the high byte of the SCSI data bus
will the LSI53C040 see as bit SCSI High ID 0
Enter a number between
8
and
15
.
If you accidentally enter the same ID value more
than once, the program will return to the
beginning of these questions, so you have the
opportunity to start over rather than being forced
to select only from the remaining choices.
What SCSI ID do you want for the SAF-TE
processor
Enter a number between
0
and
15
.
Based upon your SCSI Data signal assignments
above, you can assign a SCSI ID between
0
and
15
to the LSI53C040.
Note:
If the ID selected here is not possible based
on your answers to the previous three questions,
the program starts over at the beginning of the
previous three questions.
Four possible slow blink rates and four possible fast blink rates are available in the LSI53C040. The
following questions assign specific rates for slow and fast blink rates. LEDs are used to indicate
various conditions such as identify slot or device faulty. See the LED blink pattern section for default
blink settings.
Prepare to enter fast and slow blink rates:
Blink rates are proportional to input clock
frequency.
Fast and slow blink rates can be set from 0 to 3.
A blink rate of 2 is twice as fast as a blink rate of
3.
A blink rate of 1 is twice as fast as a blink rate of
2.
The fast blink rates are 4 times as fast as the slow
blink rates.
Fast blink rates of 2 and 3 are the same as slow
blink rates of 0 and 1.
Which of the 4 possible blink rates would you like
for the fast blink rate (0 is the fastest, 3 is the
slowest)
The blink rates are proportional to the input clock
frequency. See the "System Registers," chapter in
the
LSI53C040 Enclosure Services Processor
Technical Manual
for example blink rates based
on a 20 MHz or a 40 MHz clock.
