Power supplies
The expansion adapter in the K2 Level 2 has two Fibre Channel ports: FC-IN and
FC-OUT. HSSDC (copper) Fibre Channel cabling connects the FC-IN port to a K2
Level 2 RAID. This extends the Fibre Channel loop of the corresponding K2 Level 2
RAID chassis. There is a port status LED for each Fibre Channel port. Refer to
“Interpreting expansion adapter status LEDs” on page 45
An expansion chassis diagnostic connection is provided for communication of system
status information between the RAID controller and an expansion adapter. This is
required to use the NetCentral monitoring software. Refer to your K2 Storage System
Instruction Manual for information how these connectors are used.
NOTE: The K2 Level 2 Expansion chassis and K2 Level 2 RAID Controller chassis
must be powered on and off in the proper sequence. Refer to proper power
procedures in
Chapter 2, “K2 Level 2 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 2 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 2 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 2 External RAID chassis. Each power supply has status LEDs visible
from the rear panel. The status LEDs are described in the
. You can add or remove one power supply in the RAID
Storage Chassis while the RAID Storage Chassis is powered up.
