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 end-nodes connected to the ports on the switch can be a network
adapter card, hub, repeater, router, or another switch.
❑
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.
❑
A twisted pair port using the Auto-Negotiation feature to configure
the Auto MDI/MDI-X. It configures itself automatically as MDI or
MDI-X when connected to an end-node. Either a straight-through or
crossover twisted pair cable can be used to connect a switch port to any
network device.
