AT-FS750/16 and AT-FS750/24 Fast Ethernet Smart Switches Installation Guide

Cabling the Switch

Observe the following guidelines when connecting twisted pair and fiber

optic cables to the ports on the switch:

 The connector on the cable should fit snugly into the port on the

switch. The tab on the connector should lock the connector into place.

 Because the twisted pair ports have auto-MDI/MDI-X, you can use

straight-through twisted pair cable to connect any type of network

device to the switch.

 If your network topology contains a loop where two or more network

devices can communicate with each other over more than one network

path, do not connect the network cables forming the loop until after you

have activated the Rapid Spanning Tree Protocol on the switch. Data

loops can adversely affect network performance.

 If you are creating a port trunk, configure the switch’s management

software before connecting the cables of the trunk to the switch.

Otherwise, a network loop will result which can adversely affect

network performance.

 In order for a switch port to successfully Auto-Negotiate its duplex

mode with an end node, the end node should also be using Auto-

Negotiation. Otherwise, a duplex mode mismatch can occur. A switch

port using Auto-Negotiation defaults to half-duplex if it detects that the

end node is not using Auto-Negotiation. This can result in a mismatch

if the end node is operating at a fixed duplex mode of full-duplex.

To avoid this problem, disable Auto-Negotiation on a switch port and

set the port’s speed and duplex mode manually if the end node has a

fixed duplex mode of full-duplex.
