2-6
Standalone
The switch is shipped in its standalone configuration. Adhesive rubber feet are supplied
if the switch is surface mounted. Rubber feet installation is required for proper or safe
switch operation.
To install the adhesive rubber feet:
1
Clean the four depressions at each corner of the chassis bottom so that they are free
of dust.
2
Remove the rubber feet from the sheet and place one in each depression.
3
Firmly press the rubber feet in place.
Fiber Channel Cable Connections
All network cable connections are to the switch’s front panel. All recommended cabling
supports the switch’s 1.0625-Gbps transfer rate, as shown in Table 2-1.
NOTE:
The switch is not designed to interoperate with devices using
an Open Fibre Control optical interface.
