IBM TotalStorage FAStT EXP700, Installation And User Manual

Page: 58 / 100

Complete the following steps to turn off the power:
1. Check the system documentation for all hardware devices you want to turn off
and determine the proper shutdown sequence.
2. Make sure that all input/output activity has stopped.
3. 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.
Note: Be sure to turn off the FAStT EXP700 after or at the same time as you
turn off the storage server.
4. Turn off both power-supply switches on the back of the expansion unit.
Performing an emergency shutdown
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 expansion unit loses power unexpectedly, it
might be due to a hardware failure in the power system or in the midplane of the
expansion unit.
Complete the following steps to shut down the system during an emergency:
1. Stop all activity and check all of the LEDs. Make a note of any Fault LEDs that
are lit so that you can correct the problem when you turn on the power.
2. Turn off all power-supply switches; then, unplug the power cables from the
expansion unit.
Restoring power after an emergency
Complete the following steps to restart the expansion unit if you turned off the
power-supply switches during an emergency shutdown, or if a power failure or
power outage occurred:
1. After the emergency situation is over or power is restored, check the expansion
unit for damage. If there is no visible damage, continue with step 2; otherwise,
have your system serviced.
2. After you check the expansion unit for damage, ensure that the power switches
are in the off position; then plug in the expansion-unit power cables.
3. Check the system documentation of the hardware devices that you want to turn
on and determine the proper startup sequence.
Note: Turn on the FAStT EXP700 before or at the same time as the controller.
4. Turn on the power to each device, based on the startup sequence.
5. Turn on both of the power supply switches on the FAStT EXP700. The green
LEDs on the front and the back of the expansion unit should remain lit. If other
amber Fault LEDs are lit, see Chapter 4, “Solving problems” on page 49.
