Installing the Switch

❑

Refer to Table 5 for the cabling specifications for the fiber optic port

operating in half-duplex mode.

1. The total distance of the fiber optic lengths cannot exceed the limits stated in the table. Each media converter used

inline within a single collision domain reduces the overall segment length by 40 m (131 ft).

Selecting a Site

Be sure to observe the following requirements when choosing a site for your

switch.

❑

Select a site that is dust-free and moisture-free.

❑

Be sure that the site will allow you to easily access the fiber optic and

twisted pair cables and the power cord.

❑

Use dedicated power circuits or power conditioners to supply reliable

power to the device.
