4.2 Operation
Galaxy router is an embedded hardware and software platform. Normally, it is
working without any manual operation. It provides a reliable and flexible data
channel for industrial applications.
Galaxy router should be installed at place with good radio signal receiving. For
the cabinet and basement environment, we recommend to extend the antenna.
For outdoor use, lightning should be considered. We propose to install an
arrester between antenna and the ANT interface. Contact Hongdian technical
support department for details.
4.3 Trouble Shooting
Problem 1: All LEDs are not lights-up.
Check all cables that are connected to the router.
Check the power supply adapter output voltage.
If the power is correct and there is no LED lights-up, the router may be
failed. Contact to Hongdian or reseller for repairing.
Problem 2: Router works not stable after long time operation.
Check router cabinet temperature, if it is overheating, place the router at the
place with good ventilation.
Problem 3: Router does not run self-test when it is powered on.
Check the power adapter.
Problem 3: Update failed
System boot system and application program are stored at different memory
allocation; failed update will not affect the router rebooting. Re-update the
firmware until it is working.
