Normal operation, data
being sent and received
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 44.
Problem: receive modem
READY LED not on
If the DW4020 is not operating normally and the receive
modem’s READY LED is not lit, as shown in Figure 45, 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 46. 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.
Note: Often, if the receive modem READY LED is not lit, the
other modem LEDs will not be lit either.
