DANGER
Electrical voltage and current from power cables are hazardous. To avoid
a shock hazard, always place electrical equipment on dry, static-free level
surfaces. Never turn on any electrical equipment when there is evidence
of fire, water, or structural damage.
4. Unpack the new drives. Set the drives on a dry, static-free level surface, away
from magnetic fields. Save the packing material and documentation in case
you have to return the drives.
5. Complete the following steps:
a. Stop all I/O activity to the storage subsystem and attached storage
enclosures.
b. Ensure that all of the green drive activity LEDs on the front of the storage
subsystem (and on all attached storage enclosures) are not flashing.
c. Ensure that the green cache active LEDs are off. See “Controller LEDs” on
page 90 for the location of the cache active LEDs.
d. If applicable, use the operating-system software to disconnect the storage
subsystem logical drives from the host before you power-off the storage
subsystem.
Attention: To turn off all power to the storage subsystem, you must turn off
both power-supply switches and disconnect both power cords. Use the
procedure in step 6 for the correct shutdown sequence.
6. Turn off the power to each device according to the following shutdown
sequence:
a. Turn off power to the host before you turn off power to the storage
subsystem. If the host must stay powered-on to support a network, see the
operating-system documentation for information about disconnecting the
storage subsystem logical drives from the host before the storage
subsystem is powered-off.
b. Turn off power to the storage subsystem before you turn off power to the
storage enclosures. Turn off both power-supply switches on the rear of the
storage subsystem.
c. Turn off power to other supporting devices (for example, management
stations or Ethernet switches).
7. Use the procedures in “Replacing a hot-swap drive” on page 126 to remove
the drives that you want to replace. Use the procedures in “Installing a hard
disk drive” on page 124 to install the new drives in the storage subsystem.
8. After you install all the new drives, check the system documentation for the
hardware devices that you intend to power-on, and then determine the correct
startup sequence. Use the following power-on sequence, where applicable:
a. Turn on the power to the supporting devices (for example, Ethernet
switches and management stations) before you turn off power to the
storage subsystem.
b. Turn on the storage enclosures before the storage subsystem. The
controllers might not recognize the correct configuration if the drives are
powered-on after the storage subsystem. For instructions for powering-on
the storage subsystem, see the storage subsystem documentation.
c. Turn on the power to the storage subsystem; then, restart or turn on the
power to the host.
9. Turn on the power to each device, according to the power-on sequence in step
8. To turn on power to the storage subsystem and the storage enclosures, turn
