CrossFire 8600/8605 Token-Ring Switches v. 1.2, P/N: 710001641 Troubleshooting
Procedure B
Use this procedure if the ERR LED is on:
1. Verify that the power to the internal power supply is on. If the power is off (and
the switch is powered only by the redundant power supply), apply power to the
internal power supply. If the ERR LED turns off after this, resume using the
switch, otherwise proceed to step 2 below.
2. Reset the switch by disconnecting the power cord, waiting 10 seconds, and then
reconnecting it to the electrical outlet. If the problem goes away, resume using
the switch.
3. If you have just downloaded new microcode, clear NVRAM and reset the
switch using the instructions in “Reset Screen” on page 142.
➽ Note:
Clearing NVRAM returns all configuration parameters to their default
values.
If the problem is corrected, resume using the switch.
4. One or more bad ports can cause this symptom, and the remaining ports might
continue to operate.
— Reset the switch and monitor the diagnostic messages that appear for port
failures. The section “Diagnostic Screen” on page 72 includes a sample
diagnostic screen. Try to correct any individual port problems that are
detected.
— If the failing ports are expansion module ports, use the expansion module
documentation to try to correct the problem.
— If the problem is corrected, resume using the switch.
5. If the problem does not go away, the problem is in the switch.
Procedure C
Use this procedure if all devices connected to the switch are having communication
problems, the ERR LED is off, and the PWR LED is on:
1. Reset the switch by disconnecting power cord for 10 seconds.
— If the problem goes away, resume using the switch.
— If the status LEDs indicate a failure, go to “Procedure B”.
— If the problem persists, check all the configuration parameters.
— If the problem has still not been resolved, go to “Procedure D” and try to
get individual ports working.
