ASYNC ROUTER AR-P, AR-5, AND SYNC ROUTER USER’S MANUAL

C.3.2 ROUTER CANNOT START—LEDS STAY LIT

Although the boot diskette seems to boot properly and the Router LEDs stay lit, it will not start and will not give a prompt.

Possible cause—You may have infected the boot diskette with a virus.

If you have inserted the Router boot diskette into a PC on your network, it is possible that a computer virus was transferred to it.

Suggestion—Try using the backup boot diskette. Make sure you boot the diskette directly from the RouterVu or the Router. If you’ve corrupted your backup boot diskette, then call for technical support and order a new diskette. If you have virus-detection software, run it on the boot diskettes.

C.3.3 PROMPT IS NOT DISPLAYED

No prompt is displayed on the console after the boot diskette appears to have been successfully read at system start.

Possible cause—The console terminal may not be connected or configured correctly.

Suggestion—See if the console works by connecting the console terminal to another machine. Verify that the null-modem cable is connected from the Router’s console port to a terminal configured with a 9600 baud rate, no parity, 8 data bits, and 1 stop bit.

C.3.4 ROOT PASSWORD DOES NOT WORK

Possible cause—The root password may have been changed, or you may have forgotten the password. Follow the instructions below to recover the password.

You can recover the system using the following procedure. These steps must be completed using a serial-port console. This procedure will not work from a remote telnet or RouterVu session.

1.Eject the boot diskette.

2.Write-protect the boot diskette, as shown in Figure C-4.

Figure C-4. To write-protect the disk, turn it over and open the window at the top left-hand corner.
