Chapter G: ShoreGear Switches ShoreGear-T1 and ShoreGear E1 Voice Switches
ShoreTel 8 Planning and Installation Guide 351
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.
G.14.2.2 Network LEDs
The network LEDs (LAN1 and LAN2) indicate the speed at which the switch is
communicating with the network and whether there is network activity. The network LED
descriptions are as follows:
Link/Activity: When lit, this LED indicates that the switch is connected to an
Ethernet network. This LED indicates network activity, as follows:
When flashing, network activity is detected.
When on (not flashing), heavy network activity is detected.
When off, network activity is not detected.
This LED is not directly related to any switch’s individual network activity. For
example, if three switches are connected to the same hub and one switch’s Traffic
LED shows activity, the other switches will indicate the same activity.
When green, the switch is connected to a 100BaseT network.
When off, the switch is connected to a 10BaseT network.
G.14.2.3 Monitor and Telco LEDs
The Monitor and Telco LEDs indicate line coding, network framing, and loopback status.
These LEDs are color coded—green, yellow, and red. The Monitor and Telco LED
descriptions follow.
Telco and Monitor LED alarms and errors are logged as switch events in ShoreWare
Director’s event log.
Line Coding: This LED indicates line coding status, as follows:
When green, the line coding signal is good.
When yellow, bipolar violations (BPV) are being received at one second
When red, a loss of signal (LOS) has occurred.
When flashing red, loopback is active (local or CO).
When off, the switch has no power.
Framing: This LED indicates network framing status, as follows:
When green, the T1/E1 signal is in frame; the signal is synchronized.
