Fan tray failure

CAUTION:
To ensure good ventilation for the switch:
• Install two fan trays of the same model on the switch. Do not power on the switch when it does
not have fan trays or has only one fan tray installed.
• If both fan trays fail, replace the fan trays within 2 minutes.
• If one fan tray fails, perform either of the following tasks:
If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24
hours and make sure the failed fan tray is in position before the replacement.
If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
When a fan tray has problems, the system status LED is steady red and the system outputs alarm
messages.
To replace a failed fan tray, see

Configuration terminal problems

If the configuration environment setup is correct, the configuration terminal displays booting
