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.
