Stand-alone Switch Installation Guide for 8100L and 8100S Series Switches

The 10/100/1000Base-T ports must be set to Auto-Negotiation, the default setting, to operate at 1000Mbps.

The default duplex mode setting for the ports is Auto-Negotiation. This setting is appropriate for ports connected to network devices that also support Auto-Negotiation for duplex modes.

The default duplex mode setting of Auto-Negotiation is not appropriate for ports connected to network devices that do not support Auto-Negotiation and have a fixed duplex mode. You should disable Auto-Negotiation on those ports and set their duplex modes manually to avoid the possibility of duplex mode mismatches. A switch port using Auto-Negotiation defaults to half- duplex if it detects that the end node is not using Auto-Negotiation, which can result in a mismatch if the end node is operating at a fixed duplex mode of full-duplex.

Here are the guidelines to cabling the 100Base-FX fiber optic ports:

The cable specifications for the 100Base-FX fiber optic ports are listed in Table 4 on page 29.

Do not remove the dust covers from the fiber optic ports until you are ready to connect the fiber optic cables. Dust contamination can adversely affect the operations of the ports.

The connectors on the cables should fit snugly into the ports, and the tabs should lock the connectors into place.

These guidelines apply to both the twisted pair and fiber optic ports:

If the switch will have a static or an LACP port trunk, you should create the trunk first using the switch’s management software before connecting the cables of the trunk. Otherwise, a network loop will result which can adversely affect network performance.

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 that form the loop until after you activate one of the spanning tree protocols on the stack. Data loops can adversely affect network performance. For background information on the spanning tree protocols, refer to the AT-8100 Series AlliedWare Plus Command Line Interface User’s Guide.
