Powering up and reading
the DW4020 LED display
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.
