K2 Level 3 RAID Storage power-up and
initialization
This section gives information about connecting power and powering-on the
K2 Level 3 RAID Storage system.

Connecting electrical cables

For each chassis, there are two electrical cables (one for each power supply) that
should be connected to separate outside power sources.

To prevent the plug from being inadvertently disconnected, secure the electrical cable
into the outlet by doing the following:
1. Check that the power switch on the RAID chassis and those on the host system are
all set to OFF.
2. Insert the power cord into the power supply.
3. Secure the power cord with the stopper.
4. Insert the plug of the power cord into an AC outlet. Use a grounded AC outlet.

Powering-up the K2 Level 3 RAID Storage system

1. Power-up the Level 3 Expansion Expansion chassis prior to or at the same time as
the K2 Level 3 Controller chassis.
NOTE: You must always power-up the Level 3 Expansion Expansion chassis prior
to, or at the same time as, the K2 Level 3 RAID controller chassis. Failure to do so
may prevent some LUNs in the expansion chassis from being recognized.

K2 Level 3 RAID Storage power-up and initialization

WARNING: Make sure the power cords meet local safety and electrical
standards.
CAUTION: The K2 Level 3 RAID Storage system must be electrically
grounded. Operating the system without proper grounding can damage
disk drives. If the outlet you use is not grounded, make sure that a
licensed electrician replaces it and installs a grounding conductor.
