Nighthawk SX10 Sometimes a red light on 10-Gigabit/Multi-Gigabit port 1 uplink
Hello,
I have a Nighthawk SX10 switch. Sometimes I see a red light on 10-Gigabit/Multi-Gigabit port 1 uplink. The manual says that the red light will turn on if the switch on any port detects a loop. I have from the wall jack to the switch port one uplink. Then from ports 3-8 plugged in with my devices. Sometimes, I see port one turning from blue to red. How can I fix this problem? The other end of the wall jack is plugged into a cisco 48 port switch model catalyst 9200 48 poe+.
