LED Descriptions
Power LED
The ShoreTel-220E1 has one power LED, which indicates the following:
 On: The switch is operating normally.
 Off: The switch has no power.
 Flashing

2 flashes — The switch failed its internal self-test. This indicates a hardware failure; replace
the unit and submit a Return Material Authorization (RMA) to ShoreTel, Inc.

3 flashes — Booting via FTP. Flash memory might be corrupted. Go to the Quick Look page to
ensure that the system is running properly.

4 flashes — The IP address is unavailable. DHCP and BOOTP did not respond to the IP
address request, and the IP address is not available in nonvolatile memory to continue boot
process. The switch will automatically reboot in five seconds and try again. Check the BOOTP/
DHCP server and the network configuration to ensure that the voice switch is receiving a valid
IP address.
