Planning the Installation

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

your switch.

❑ The end-nodes connected to the twisted pair ports can operate at 10

Mbps or 100 Mbps and half or full-duplex. The switch uses auto-

negotiation to determine the correct speed and duplex mode for each

port.

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

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

amplifiers electrical motors, and fluorescent fixtures.

❑ Refer to Table 2 for the cabling specifications for the twisted pair

ports.

switch.

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

❑ Be sure that the site will allow you to easily access the twisted pair

cables and the power cord.

❑ Use a dedicated power circuit or a power conditioner to supply reliable

power to the device.
