Table 1 provides additional information about the LEDs and what
they indicate.
Startup LED test
Immediately after power-up or a reset, all LEDs are lit for 1 sec
while the terminal performs a self-test. After the self-test, the
LEDs should appear as described in the next section, Normal
operation.
Normal operation
When the terminal is powered on and transmitting or receiving
data, the LEDs should appear as follows:
• LAN, Transmit (HN7000S) or Transmit/WAN (HN7700S),
and Receive (HN7000S) or Receive/PPP-IP (HN7700S)
LEDs – Mostly on, but blinking intermittently as the terminal
receives and transmits data.
• System LED – On, indicating that the terminal has
established communication with the NOC. On an HN7700S,

Blinking, mostly on Transmitting data.
Blinking, mostly off The terminal is ranging (measuring the distance to the
satellite to calibrate transmit timing and transmit power).
Off Condition preventing transmission.

(VADB).
Blinking Virus protection blocking data.
Off Condition preventing full operation.
Power Solid Power is on and terminal is functioning normally
Flashing Terminal is operating with the fallback.bin (backup)
version of software.
Off No power.
