G.16.1 LED Descriptions
G.16.1.1 Power LED
The IPBX-12 has one green power LED, which indicates the following:
•On: The switch is operating normally.
•Off: The switch has no power.
—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
—3 flashes—Booting via FTP. Flash memory may be corrupted. Go to the Quick
Look page to make sure 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.
—5 flashes—The operating system is not available. The switch is booting from
FTP but cannot find the boot files. It automatically reboots in five seconds. You
can use BOOTP or DHCP to tell the switch where the files are. If you are using
BOOTP, set the BOOTP server to the IP address of the ShoreWare server, and
set the boot file to /ts12/vxworks. If you are using a DHCP server that
supports options 66 and 67, set option 66 to the ShoreWare server’s IP address,
and set option 67 to /ts12/vxworks.
—6 flashes—Using a previously stored IP address. A BOOTP/DHCP transaction

continues to use the IP address stored in nonvolatile memory until it receives a
valid response. If the switch receives a response that provides a different IP
