Front panel LEDs
The satellite router has five LEDs on the front panel, as shown in
Figure 24: Front panel LEDs
on the HN9400 router
on page 28. By their appearance—on, off, blinking, or flashing—the
LEDs indicate the router’s operating status. All are blue when lit. The front panel LEDs are all
blue when lit.
Figure 24: Front panel LEDs on the HN9400 router
Table 8: Front panel LED indications
on page 28 explains what the router status is when the
LEDs are on, off, or blinking.
On
means the LED is continuously lit.
Blinking
means the LED
is usually on, but intermittently turns off briefly.
Flashing
means the LED alternates between
on and off for periods of ½ sec to 1 sec.
