Booting: Scrambled Output When Booting from ROM
Possible Problem
Solution
Wrong terminal
speed setting
1.
Use the monitor setup menu to check the terminal line speed
setting for the monitor.
2.
Check the terminal speed configured on the router as
specified in the configuration register setting (default is 9600
baud, 8 data bits, 2 stop bits, and no parity).
3.
If the terminal speed of the monitor and the router do not
match, modify as necessary.
Refer to your hardware installation and maintenance
documentation for details about setting up the monitor.
Router hardware
problem
Check all hardware for damage, including cabling (broken wire),
adapters (loose pin), router ports, and so forth. For more
information, refer to the information in the "Troubleshooting
"Hardware section found earlier in this chapter.
Booting: Local Timeouts Occur When Booting from ROM
Symptom:
“Local timeout” error messages are generated when a user is booting from ROM. The router
is incapable of completing its boot process and will not start the ROM monitor.
Table 3-19 outlines the problem that might cause this symptom and describes solutions to that problem.
Table3-19
Booting: Local Timeouts Occur When Booting from ROM
Possible Problem
Solution
EPROM problem
Generally, this problem occurs only if you have just replaced
your system EPROMs.
1.
Power down the system.
2.
Inspect each EPROM. Make sure that each EPROM is
correctly positioned in the socket (with notches properly
aligned) in the correct socket.
3.
If a pin is bent, straighten it carefully. Reinstall the EPROM
and power up the system. If a pin breaks off, the EPROM
must be replaced.
4.
If an EPROM has been installed backward and power has
been applied to it, the EPROM has been damaged and must
be replaced.
5.
If local timeouts persist, contact your technical support
representative.
