Chapter 4: Cabling the Network Ports

Cabling the 10/100/1000Base-T 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 10/100/1000Base-T 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, make sure that your switch is properly configured with the appropriate protocol(s); i.e., STP, ESPR, LACP, etc. Data loops without these protocols enabled 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.
