Installing the Switch

❑Refer to Table 5 for the cabling specifications for the fiber optic port operating in half-duplex mode.

Table 5 100Base-FX Fiber Optic Ports (Half-duplex)1

Number of Switches	Connected Devices	Maximum Operating
		Distance
One switch inline	Switch to switch	372 m (1,221 ft)
	Workstation to switch	372 m (1,221 ft)
	Switch to Class I	137 m (450 ft)
	repeater
	Switch to Class II	185 m (607 ft)
	repeater
Two switches Inline	Switch to switch	332 m (1,089 ft)
	Workstation to switch	322 m (1, 089 ft)
	Switch to Class I	97 m (318 ft)
	repeater
	Switch to Class II	145 m (476 ft)
	repeater

1.The total distance of the fiber optic lengths cannot exceed the limits stated in the table. Each switch used inline within a single collision domain reduces the overall segment length by 40 meters (131 feet).

Selecting a Site

Be sure to observe the following guidelines when selecting a site for your switch.

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

❑Select a site that allows you to easily access the data cables and power cord.

❑Use dedicated power circuits or power conditioners to supply reliable power to the device.
