Switch modules to control ownership of the disk modules and data paths. To control
switch modules, you can either:

•

Physically toggle a switch on a switch card

•

Use software such as the ServerNet Nomadic Disk switch command interface
(SWCI) or Nomadic Disk Manager

The following figure shows the faceplate of a switch module.

Switch modules contain:

•

A switch controller card (SCC) in slot 0, which provides a communication link
between switch cards and a server.

•

Switch cards in slots 1 through 8, which determine the path of fiber-optic signals
between a node and the 45xx disk modules. .

Note. Although it is possible to connect other types of servers to the switch module, Himalaya
S-series servers are the only servers documented in this guide.
