4. Enter new IP address, gateway and subnet mask.
5. Click modify，then exit, it is done. There will show new IP address and gateway on operational logbook.
6. Reboot the transponder, the new IP take effect (Click the reboot button in the network management
software or power on again)
10. Clean and maintenance method of the optical fiber active connector
In many times, we consider the decline of the optical power as the equipment faults, but actually it may be caused as the optical
fiber connector was polluted by dust or dirt. Inspect the fiber connector, component, or bulkhead with a fiberscope. If the
connector is dirty, clean it with a cleaning technique following these steps:
10.1 Turn off the device power supply and carefully pull off the optical fiber connector from the adapter.
10.2 Wash carefully with good quality lens wiping paper and medical absorbent alcohol cotton. If use the medical absorbent
alcohol cotton, still need to wait 1~2 minutes after wash, let the connector surface dry in the air.
10.3 Cleaned optical connector should be connected to optical power meter to measure output optical power to affirm whether
it has been cleaned up.
10.4 When connect the cleaned optical connector back to adapter, should notice to make force appropriate to avoid china tube
in the adapter crack.
10.5 The optical fiber connector should be cleaned in pairs. If optical power is on the low side after clean, the adapter may be
polluted, clean it. (Note: Adapter should be carefully operated, so as to avoid hurting inside fiber.
10.6 Use compressed air or degrease alcohol cotton to wash the adapter carefully. When use compressed air, the muzzle aims
at china tube of the adapter, clean the china tube with compressed air. When use degrease alcohol cotton, insert directions
need be consistent, otherwise can’t reach a good clean effect.
