Operation 1-9

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.
