Other devices
connected to the
terminal
If a device other than a computer is connected to the terminal, the
System Control Center is probably never accessible. However,
you can troubleshoot using the following LED conditions:
•
Receive LED is not illuminated
•
System LED is not illuminated
•
Power LED is not illuminated
•
Power LED is blinking
Receive LED is not
illuminated
If the terminal is not operating normally and the receive LED is
not illuminated, take the following steps:
1. Check all cable connections. See Figure 26. Tighten any that
seem loose.
2. If the LED still does not come on, power cycle the terminal
by unplugging the power cord from the power source,
waiting 10 seconds, and plugging it back in.
3. If the problem persists, contact customer support.
System LED is not
illuminated
If the System LED is not illuminated, but the Transmit and
Receive LEDs are on, there may be a problem at the NOC.
Follow these steps:
1. Wait awhile. If there is a problem at the NOC, it will soon be
corrected and the System LED will come on. You can then
resume normal operation.
2. If the LED does not come on after you have waited awhile,
power cycle the terminal by unplugging the power cord from
the power source, waiting 10 seconds, and plugging it back
in.
3. If the problem persists, contact customer support.
Power LED is not
illuminated
If the Power LED is not illuminated, take the following steps:
1. Make sure the DC power cord is securely attached to the
terminal. See Figure 26.
2. If securing the DC power cord does not solve the problem,
check all cable connections. Tighten any that seem loose.
Note: Often, if the Receive LED is not on, the other LEDs may
not be on.
