Level 3 RAID Instruction Manual

Chapter 1 About the K2 Level 3 RAID storage

The expansion adapter in the K2 Level 3 has two Fibre Channel ports: FC-IN and
FC-OUT. HSSDC (copper) Fibre Channel cabling connects the FC-IN port to a K2
Level 3. This extends the Fibre Channel loop of the corresponding K2 Level 3 chassis.
There is a port status LED for each Fibre Channel port. Refer to

“Interpreting

expansion adapter status LEDs” on page 42

.

NOTE: The K2 Level 3 Expansion chassis and K2 Level 3 Controller chassis must
be powered on and off in the proper sequence. Refer to proper power procedures in

Chapter 2, “Level 3 RAID Installation Information”

.

Power supplies

There are two auto-ranging power supplies, power cord and standby switch. Each
supply supports a fully configured K2 Level 3 External RAID and shares load
currents with the other supply, if it is present. The power supplies are designed so as
to protect the disk drives if you install them while the K2 Level 3 External RAID is
powered up. A disk with power-related faults will not adversely affect the operation
of any other disk.

The RAID chassis and the expansion chassis each have their own type of power
supply. The two types are not interchangeable.

Each power supplies includes two fan modules used to cool the components installed
in the K2 Level 3 External RAID chassis. Each power supply has status LEDs visible
from the rear panel. The status LEDs are described in the

“Interpreting power supply

status LEDs” on page 43

. You can add or remove one power supply in the RAID

Storage Chassis while the RAID Storage Chassis is powered up.
