Switch Port LEDs
The IPBX-12 has two LEDs for each switch port. The LED on the left indicates trunk
activity when the port is configured as a trunk port; the LED on the right indicates
telephone activity when the port is configured as a telephone port.
The LEDs are described as follows:
Network LEDs
The IPBX-12 switch’s network LEDs 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:
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/vxwork s. 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 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.
Both
• When both LEDs are off, the port has not been configured.
• When both LEDs are flashing, the port is out of service.
Trunk LED (left)
• When on, the port is configured as a trunk port.
• When flashing fast, the trunk is in use (call in progress).
Telephone LED
(right)
• When on, the port is configured as a telephone port.
• When flashing slowly, the telephone is off hook.
• When flashing with ring cadence, the telephone is ringing.
• When flashing fast, the telephone is in use (call in
progress).
10M When lit, this LED indicates that the switch is connected to a 10BaseT
network.
100M When lit, this LED indicates that the switch is connected to a 100BaseT
