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 10Base-T/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,
