Fiber-Optic ServerNet Cables

Single-mode, fiber-optic ServerNet cables connect each node to the ServerNet II

Switches on each fabric.

Connections Between the ServerNet II Switch PICs and

MSEB PICs

A fiber-optic ServerNet cable from a ServerNet port numbered 0 through 7 on one of

the ServerNet II Switches connects to an MSEB in each node. You must connect both

MSEBs in a node using the same ServerNet port number on the appropriate ServerNet

II Switch on the X fabric and the Y fabric.

The maximum cable distance between each node and a ServerNet II Switch is 80

meters.

Connections Between ServerNet II Switches on the Same

Fabric

Ports numbered 8 through 11 connect ServerNet II Switches on the same fabric

together. You use either a two-lane link or four-lane link depending on your topology.

When cabling these ports, note that ports 8 and 9 are located to the right of ports 10

and 11.

ServerNet II Switch Connects to...

X fabric Port 6 in the MSEB in group 01, module 01, slot 51

Y fabric Port 6 in the MSEB in group 01, module 01, slot 52
