Planning the Installation

Be sure to observe the following guidelines when planning the installation of

your switch.

❑ The end-node connected to the 100Base-FX fiber optic port must be

able to operate at 100 Mbps.

❑ The end-node connected to the 10/100Base-TX twisted pair port can

operate at either 10 Mbps or 100 Mbps.

❑ The end-node connected to a port on the switch can be a network

adapter card, repeater, router, hub, or another switch.

❑ The twisted pair cabling must be kept away from sources of electrical

noise, such as radios, transmitters, power lines, broadband amplifiers,

electrical motor, and fluorescent fixtures.

❑ Refer to Table 3 for the cabling specifications for the twisted pair port.

❑ Refer to Table 4 for the cabling specifications for the fiber optic port
