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. On the server connected to the EXP3000, close all open operating system
windows and programs; then, shut down the server and any connected RAID
controllers.
2. Make sure that all amber status or fault LEDs are off. If any status or fault LEDs
are lit (on hard disk drives, power supplies, or ESMs), identify or correct the
problem before you turn off the power. For more information, see Chapter 5,
“Solving problems,” on page 27.
3. 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 27.
To turn off the EXP3000 during an emergency situation, complete the following
steps:
1. On the server connected to the EXP3000, close all open operating system
windows and programs; then, shut down the server.
2. 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.
3. 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 you intend to turn
on, and determine the proper power-on sequence.
Note: Be sure to turn on the EXP3000 before or at the same time you turn on
the server.
3. Turn on each connected device, based on the power-on sequence described in
the documentation that comes with the device.
4. After you check for damage, connect the EXP3000 power cables and turn on
both power switches on the rear of the EXP3000.
5. Only the power (green) LEDs on the front and rear should be lit. If one or more
of the fault (amber) LEDs are lit, see Chapter 5, “Solving problems,” on page 27
for instructions.
