Turning on the power
Statement 5:
CAUTION:
The power control button on the device and the power switch on the power supply do not turn off the
electrical current supplied to the device. The device also might have more than one power cord. To
remove all electrical current from the device, ensure that all power cords are disconnected from the
power source.

Important: You must follow the power sequence in the order shown in the following procedure. To
establish power redundancy for enclosures with two power supplies, use at least two power
distribution units (PDUs) in the rack cabinet. Split the power connections from each enclosure
into the separate PDUs. Then, connect the PDUs to external power receptacles that are on
different circuits.
The storage expansion enclosure accepts only 200 V - 240 V input sources. In addition, you
might need to purchase a special cable for the rack PDUs for the voltage and currents that the
EXP5060 requires. If you do not have an IBM System Storage 2101-200 rack with the
supported PDUs and 60 A power cords, check your PDUs or input sources to make sure that
they can handle the EXP5060 voltage and currents.
To turn on the storage expansion enclosure power, complete the following steps:
1. Turn off all the power switches on the rear of the storage expansion enclosure. Make sure all of the
power cords are connected.
2. If the main circuit breaker switches in the rack cabinet are turned off, turn them on.
3. Turn on the power switch on each storage expansion enclosure.
4.
Turn on both power switches on the storage subsystem.
Note:
When you turn off the power to the storage subsystem and storage expansion enclosure,
complete the preceding steps in reverse order. Turn off the power to the storage subsystem
first; then, turn off the power to the storage expansion enclosures.
