The cable is used to connect the console port of the TSR 2800-20-DC modularized
router and the outside console terminal device. One end of the cable is a 8-pin RJ45
plug and the other end is a 9-hole plug (DB9). The RJ45 plug is put into the socket of
the console port on the TSR 2800-20-DC modularized router. The inner line connection
in the cable is shown in figure 3-1. The console cable is numbered as RLC0301.

3.3.2 Connecting Fast-Ethernet Interface
The 10/100M auto-adaptation Ethernet port provides the UTP (RJ45) interface and has
the 100M link/ACT indicators. The 10/100M auto-adaptation Ethernet port can be
connected to the UTP port of the router and then to HUB through the twisted pair. The
numbering order of the pins in the UTP port is the same as the console port.
