When the AT-VP504E FXS initiates a software download, the three
LEDs located on the front panel are used to report the status of the
process:
Interpreting the
LEDs in Reset
Mode
When resetting the AT-VP504E FXS at boot time, the three LEDs start
blinking. If you hold the
Default Settings switch less than 15 seconds,
the IP address of the unit will default to the static value 192.168.0.1. If
you want the unit to use a DHCP-provided address, you will then have
to set the
interfaceUseDhcp Provisioning MIB variable to 1 and reboot
the unit.
If you hold the
Default Settings switch at least 15 seconds, the three
LEDs will stop blinking – remaining ON – indicating that the MIB
database and the rescue application’s file have been rebuilt and default
values set. Upon releasing the
Default Settings switch, the AT-VP504E
FXS will reboot. See “Using the Dual-Mode Default Settings Switch” on
page 22 for more information.
