Cabling the Twisted Pair and Fiber Optic Ports
Observe the following guidelines when connecting a twisted pair or fiber
optic cable to a port 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 on the switch are auto-MDI/MDI-X, any
type of network device can be connected to a port on the switch using
a straight-through twisted pair cable. If you disable Auto-Negotiation
on the port, the port defaults to MDI-X.
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 you
have activated a Spanning Tree Protocol on the switch. Data loops 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.
