Performing a shutdown
Note: If the expansion unit loses power unexpectedly, it might be due to a
hardware failure in the power system or midplane (see “Symptom-to-FRU
index” on page 108).
Perform the following steps to shut down your expansion unit:
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
Perform the following steps to power on the FAStT EXP15 and FAStT EXP200.
v
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. For FAStT EXP15:
The option ID switch on the expansion unit is set
correctly.
For FAStT EXP200: Option switches 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 you power 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, see “Symptom-to-FRU index” on page 108.
v 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.
