ShoreGear 220T1 Voice Switch Chapter G: ShoreGear Switches
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 /tsk/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 /tsk/vxworks.
—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.6.2.2 Network LEDs
The ShoreGear 220T1 network LEDs (LAN1 and LAN2) indicate the speed at which the
switch is communicating with the network and whether there is network activity.
When both LAN connectors are connected into a redundant network configuration, one
network port is active while the other is in standby mode. If one LAN connection fails, the
switch activates the other port.
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), the switch is connected to an Ethernet network.
—When off, the switch cannot detect an Ethernet network.
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.6.2.3 Status LED
TheShoreGear 220T1 has one status LED to provide general information about the ports.
The color and blink pattern of the LED indicate the port function:
•Status LED (Green)
—When on steady, no ports are handling active calls.
—When flashing fast, at least one port is handling an active call.
•Status LED (Yellow)
—When on steady, no ports are handling active calls and at least one port is out of
