Fatal error indication If after power-up or a reset the Power LED is off and one or more
of the other LEDs is flashing, the terminal could have a fatal error
and may have to be replaced. If you do
not see these LED
indications, proceed to
All LEDs flashing
on page 57.
If there is a fatal error indication (Power LED off and other LED
or LEDs flashing), try power cycling the terminal:
1. Unplug the power cord from the power source.
(If the terminal is connected to a DC power source, unplug
the DC input cable from the terminal’s power supply.)
2. Wait 30 sec.
3. Plug the power cord back into the power source.
(If the power source is DC, plug the input cable back into the
power supply.)
The terminal may recover. If the fatal error indication continues,
the terminal must be replaced. Contact your service provider.
All LEDs flashing
If all LEDs are flashing simultaneously, this is an indication that
the terminal’s firmware is corrupted. A terminal in this state
cannot be recovered. Contact your service provider.
All LEDs are off If all the LEDs are off, the power connections may not be secure
or the power source may be faulty. Refer to Figure 45 and follow
these steps:
1. Make sure the DC power cord is securely connected to the
DC IN connector on the terminal.
2. Make sure the AC power cord is securely connected to the
power source.
If the AC power cord is connected to a power strip or surge
protector, make sure the power strip or surge protector is
turned on.
Note: The remote terminal may operate correctly when first
installed even if the transmit and receive cable connectors are not
adequately tightened. However, problems could develop later.
Therefore, correct operation of the terminal is not an indication
that the cables are adequately tightened.
CAUTION
Do not power cycle the terminal by unplugging the power
cord from the back of the terminal. This could shock you
and/or damage the terminal.
