3. Connect the cables and power to the appropriate ports on the back panel of the router, as
illustrated in Figure 2-1:
a. Connect the AC power adapter (5) to the 9v-DC port.
b. Connect the ISDN cable (8) to the ISDN port.
c. Connect the RJ-45 two-way splitter (2) to the LAN port.
d. Connect an appropriate cable to connect an analog device (6) (phone, fax, or modem)
to the Voice port.
4. Connect one of the two Ethernet 10BASE-T cables (7) to the MGR port on the RJ-45
two-way splitter (2).
5. Connect the other end of the 10BASE-T cable that you used in step 4 to the 9-pin
D-connector to RJ-45 adapter (9).
6. Connect the 9-pin D-connector to RJ-45 adapter (9) to the serial port of your PC.
Depending on what type of computer you are using, you may have to connect the 9-pin
D-connector to 25-pin D-connector (10) next or supply an adapter of your own to be able to
connect to the serial port of your PC.
7. Connect the other Ethernet 10BASE-T cable (7) to the TP port on the RJ-45 two-way
splitter (2).
8. Connect the other end of the Ethernet 10BASE-T cable (7) that you used in step 6 to the
LAN port (12) on your PC.
Connecting to ISDN
To connect your router to ISDN outside of North America, follow these steps:
1. Connect the ISDN cable (8) from the router to the ISDN wall outlet (4) (Figure 2-1).
Warning: Do not plug the ISDN cable into the LAN port on the router. Plugging the
ISDN cable into the LAN port causes serious damage to the router.
