Reset button
The Reset button is recessed within a hole on the front panel. Use a straightened
paper clip or similar object to press the Reset button. The Reset button allows
technicians to reset the switch, as follows:
•
Press Reset: The switch resets and reloads the configuration files with a dump file.
•
Press and hold Reset for five seconds: The switch resets and reloads the
configuration files.
Fans
Four internal hot-swap fan modules cool the switch unit. If an individual fan module
fails, the other fans continue to run, and the switch unit continues to operate
normally. You can replace a hot-swap fan module while the switch is operating.
Fan operation and internal temperatures are monitored. If the air temperature
exceeds a threshold, the environmental monitor displays warning messages.
Note:
If a fan module fails, the maximum operating temperature drops from 40°C to
35°C (104°F to 95°F).
The Service ( ! ) LED flashes and the Fan LED flashes if there is a failure of one or
more fan modules. The failed fan module LED (rear panel) flashes to indicate a
failure.
