A power outage or emergency situation occurs. See “Turning off the EXP3000 in
an emergency.”
To turn off the EXP3000, complete the following steps:
1. Make sure that all amber status or fault LEDs on the EXP3000 are off. If any
status or fault LEDs are lit (on hard disk drives, power supplies, or ESMs),
identify or correct the problems before you turn off the power. For more
information, see Chapter 5, “Solving problems,” on page 37.
2. On the server to which the EXP3000 is connected, either directly or through
another supported device that contains a RAID controller to which the EXP3000
is connected, close all operating-system windows and programs; then, shut
down the server.
3. Shut down any device that contains a RAID controller to which the EXP3000 is
connected.
4. Turn off both EXP3000 power supplies.
Turning off the EXP3000 in an emergency
Attention: Emergency situations might include fire, flood, extreme weather
conditions, or other hazardous circumstances. If a power outage or emergency
situation occurs, always turn off all power switches on all computing equipment.
This will help safeguard your equipment from potential damage due to electrical
surges when power is restored. If the EXP3000 loses power unexpectedly, it might
be due to a hardware failure in the power system or midplane. See Chapter 5,
“Solving problems,” on page 37.
To turn off the EXP3000 during an emergency situation, complete the following
steps:
1. If you have time, stop all activity and check the LEDs (front and rear). Make
note of any status or fault LEDs that are lit so that you can correct the problem
when you turn on the power again.
Note: See the documentation that comes with your RAID controller for
information about correcting the problem.
2. On the server to which the EXP3000 is connected, either directly or through
another supported device that contains a RAID controller to which the EXP3000
is connected, close all operating-system windows and programs; then, shut
down the server.
3. Shut down any device that contains a RAID controller to which the EXP3000 is
connected.
4. Turn off both EXP3000 power supplies; then, disconnect the power cables from
the EXP3000.
Turning on the EXP3000 after an emergency
To restart the EXP3000 if you turned off the power supplies during an emergency
shutdown, or if a power failure or a power outage occurred, complete the following
steps:
1. After the emergency situation is over or power is restored, check the EXP3000
for damage. If there is no visible damage, continue with step 2; otherwise, have
your unit serviced.
2. Check the system documentation for the hardware devices that you intend to
turn on, and determine the correct power-on sequence.
