Alert Indicator
The Alert Indicator is used to indicate the configuration and
software download status of the modem.
Immediately after power-up, the indicator will light orange
for one second. Then, if the Configuration Reset button
has been pressed while powering-on the unit, the indicator
will flash green five times a second for four seconds.
In any case, the indicator will then flash orange twice a
second for four seconds during which the modem will
accept software download through the serial port (see
Chapter 5 of the CLI User's Guide for a description of the
Software Update process).
Approximately ten seconds after power-up, the Alert
Indicator will begin flashing green twice a second while the
unit's software is loading. It takes about 30 seconds for the
unit to complete downloading. Once the download is
complete, the indicator will be turned off.
PWR Indicator
The PWR Indicator lights green when power is applied. If
this indicator is off, check to be sure that the power cable is
connected at the rear panel, and that the power adapter is
plugged in.
LAN Status Indicator
The LAN Status Indicator lights green when your modem is
connected to your PC or Ethernet LAN.
If the connection to the LAN is broken, the indicator will go
off and remain off. Be sure that the computer or hub cables
are properly connected at the rear panel and at your PC or
Ethernet hub. Also, check to make sure that the MDI/X
(Ethernet Crossover) switch is properly set.
