C.3.2 R OUTER C ANNOT S TART —LED S S TAY L IT
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 P ROMPT I S N OT D ISPLAYED
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 R OOT P ASSWORD D OES N OT W ORK
Possible cause—The root password may have been changed, or you may have forgotten the password.

serial-port console. This procedure will not work from a remote telnet or RouterVu session.

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