Chapter 1 About the K2 Level 2 RAID storage
The RAID controller module has two Fibre Channel ports: the Host Fibre Channel
Port and the Expansion Chassis Port. The Host Fibre Channel Port requires LCC
cables (optical) for the Fibre Channel connection to a K2 Media Server or to a Fibre
Channel switch. The Expansion Chassis Port requires HSSDC cables (copper) for the
Fibre Channel connections with a K2 Level 2. 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 controller status LEDs” on page 43
When the redundant Fiber Channel option is not installed in the K2 Level 2 RAID
RAID Storage Chassis, only one RAID controller is installed. A blank fills the other
RAID controller slot.
A diagnostic cable is provided for communication of system status information
between the RAID controller and an expansion adapter. This is required, and it
supports the NetCentral monitoring software. Refer to your K2 Media Client System
Guide for information how these connectors are used.
The K2 Level 2 RAID includes a LAN card with an RJ-type connector for Ethernet
network connection. It is through this connection that SNMP status information is
communicated, for monitoring by the NetCentral system.
