TW-H6W1IR ISDN Remote Router
Installation 21
You should have now connected the RS-232 cable to the console, the
ISDN phone line, one or more Ethernet cables, and the power adapter.
At this point in the installation process you can now power up the
console computer, run the terminal emulation software (if necessary),
and then power up the TW-H6W1IR.
Step 7 - Initial Configuration of the Router
After the console is properly connected and both devices are powered
on as described in the preceding sections, you should see the router run
through the power on self test (POST). Finally, it will arrive at the logon
screen shown below. If the login screen does not appear, press
