Check the Interface Indicator Light

{{ $t('productDocDetail.updateTime') }}: 2026-01-07

Under normal circumstances, while sensing electrical signals, the LINK indicator light of the network interface remains solid green in a 100-megabit link, but solid orange in a gigabit link. The ACT indicator light of the network interface is in orange and flashes continuously in data transmitting. If the LINK or ACT indicator light does not flash or fails to be on, follow the steps below:

  1. Check whether the network cable is damaged.
  2. Check whether the registered jack of the network interface is damaged.
  3. Check whether the NIC duplex mode is negotiated and matched.
  4. If none of the said problems exists, restart the device, switch to the standby device, and contact the technical support engineer from Sangfor in time.
