Performing a Shutdown
Note
If the Expansion Unit loses power unexpectedly, it
might be due to a hardware failure in the power
system or mid-plane (see “Symptom-to-FRU Index” on
page 31).
To perform a shutdown:
1. Make sure that all I/O activity has stopped. If
applicable, logically disconnect from the host
controller.
2. Make sure that all amber Fault LEDs are off. If any
Fault LEDs are lit (drives, power supplies, or fans),
correct the problem before you turn off the power.
3. Turn off
both
power supply switches on the back of
the expansion unit.
Turning the Power On
Use this procedure to power-on the Netfinity EXP200
Storage Expansion unit.
Initial start-up:
1. Verify that all communication and power cables
are plugged into the back of the expansion unit.
a. All hard disk drives are locked securely in
place.
b. Option switchs 1 through 5 and the tray
number switch on the expansion unit are
set correctly.
c. The host controller and other SCSI bus
devices are ready for the initial power-up.
d. Power-on the expansion unit before
powering on the server.
2. Turn on the power to each device, based on this
power-up sequence.
3. Turn on
both
power supply switches on the back
of the expansion unit.
4. Only the green LEDs on the front and back
should be on. If one or more of the amber Fault
LEDs are on, refer to “Symptom-to-FRU Index”
on page 31.
Re-starting:
If you are re-starting after a normal shutdown, wait at
least ten seconds before you attempt to turn on
either
power supply switch.
