Cabling Twisted Pair Ports

To connect the data cables to the switch ports and to apply power to the switch, perform the following procedure:

If your AT-8500 Series switch has twisted pair ports, perform the following procedure:

1.Connect the twisted pair data cables to the RJ-45 ports on the switch, as shown in Figure 19.

Figure 19. Connecting the Twisted Pair Data Cables

When you connect a twisted pair cable to a port, observe the following guidelines:

ˆAn RJ-45 connector should fit snugly into the port on the switch. The tab on the connector should lock the connector into place.

ˆBecause the ports on the switch are auto-MDI/MDI-X, you can use either a straight-through or crossover twisted pair cable to connect any type of network device to a port on the switch. If you disable Auto-Negotiation on a port, the auto-MDI/MDI-X feature is disabled and the port defaults to MDI-X. For instructions on how to configure a port, refer to the AT-S62 Management Software User’s Guides.

ˆIf your network topology will contain a loop where two or more network devices can communicate with each other over more than one data path, do not connect the network cables forming the loop until after you have activated a spanning tree protocol on the switch. Data loops can adversely affect network performance. For information on spanning tree, refer to the AT-S62 Management Software User’s Guides.

ˆIf you are creating a port trunk, do not connect the cables of the trunk to the switch until you after have configured the trunk using the switch’s management software. Connecting the trunk cables to the switch before you have configured the software will result in a data loop, which can adversely affect network performance. For
