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.
