AT-GS900/8PS Switch Installation Guide

Cabling the Switch

Observe the following guidelines when connecting twisted pair and fiber optic cables to the ports on the switch:

The cable specifications for the twisted pair ports are given in Table 1 on page 19

Refer to the cable specifications are included in the SFP module data sheet for the SFP module installed.

The cable connector 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 may use straight-through or cross-over twisted pair cables to connect any type of Ethernet network devices to the switch.

The default speed and duplex settings for the ports are determined with Auto-Negotiation. The end-nodes connected to the twisted- pair ports should be configured for Auto-Negotiation to insure that both the speed and duplex modes are matched on each end.
