Hughes DIRECWAY DW4020 User Manual

After you have assembled the DW4020, plug it into a 110 V wall 
outlet, power strip, or surge protector. The Gateway LED display 
will cycle as shown in Table 12. The cycling completes in less 
than a minute.

The transmit and receive modems have their own LEDs, which 
show their status. These are described in The DW4020 LEDs on 
page 86.

Note that normal Gateway operation alone doesn't imply normal 
DW4020 operation. The installation and commissioning process 
may not have been completed or software download (DLL) from 
the Network Operations Center (NOC) may not have been 
completed. Additional status information is available via the User 
Interface. See Chapter 3 – The User Interface, on page 33) and 
the LEDs on the receive and transmit modems (see 
Communicating with the Gateway through the serial port on 
page 95).

Note:

In countries outside North America, the DW4020 may be 

plugged, with a physical adapter, directly into a 220 V outlet. 
Different countries may have different standards and requirements.
