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.
