Hughes DIRECWAY DW4020 Manual De Usuario

During normal DW4020 operation, the modems’ READY LEDs 
are continuously lit, the RX and TX LEDs blink as they pass data, 
and both the Gateway LEDs are continuously lit, as shown in 
Figure 64.

If the DW4020 is not operating normally and the receive 
modem’s READY LED is not lit, as shown in Figure 65, take the 
following steps:

• Check to make sure the power cord is securely attached to the 

receive modem and plugged into the wall outlet or surge 
protector. See Figure 66. If the power cord was loose, the 
receive modem READY led will come on when power is 
restored.

• If securing the power cord does not solve the problem, check 

all cable connections. Tighten any that seem loose.

• If the Receive modem READY LED still does not come on, 

power cycle the DW4020 by unplugging the power cord from 
the wall outlet or surge protector, waiting ten seconds, and 
plugging it back in.

• If the problem persists, contact technical support.

Often, if the receive modem READY LED is not lit, the 

other modem LEDs will not be lit either.
