The IPBX-T1 (Figure G-22) provides higher-density trunking to the central office using T1
or PRI signaling. The IPBX-E1 provides higher-density trunking using E1 PRI signaling.
The IPBX-T1 and IPBX-E1 LEDs and connectors are defined below.
G.18.1 LED Descriptions
G.18.1.1 Power LED
The IPBX-T1 and IPBX-E1 have one red 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
ShoreTel, Inc.
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.
6 flashes—Using a previously stored IP address. A BOOTP/DHCP transaction
was attempted, but the BOOTP/DHCP server did not respond. The switch
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
address, it reboots using the new IP address. If the switch receives a response
that matches the IP address stored in nonvolatile memory, it continues
operation, and the power LED stops flashing. If the problem persists, check the
BOOTP/DHCP server and network configuration.
