Transmit modem READY
LED not lit
If the transmit modem is not operating normally and its READY
LED is not lit, as shown in Figure 67, take the following steps.
•
Check that the receive modem READY LED is continuously
lit. If not, try the sequence in
Problem: receive modem
READY LED not on
on page 88.
•
Check that the 25-pin connector is attached securely. See
Figure 66.
•
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
transmit modem READY led may come on.
•
If securing the power cord does not solve the problem, check
all cable connections. Tighten any that seem loose.
•
If the transmit 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.
