10Base-T Hub Installation and Maintenance Practice

10 61181012L1-5C

Connections

All Ethernet connections are made using the RJ-45 jacks (labeled 1 through 8) located on the

rear panel. The first jack is also designated as the cross-over jack; it is controlled by the cross-

over switch located at the far right of the rear panel.

NOTE

To daisy-chain the 10Base-T Hub to other hubs, place the rear

panel switch (see

Figure 2) in the left cross-over position (×). To use

as a LAN port, put in the right position (=).

The 10Base-T Hub provides for a single voltage input, a single voltage return, and a frame

ground. Table 3 shows the connections.
