We have a 450m that we just started losing the Ethernet link on the fiber port. Using single mode fiber SFP. The switch sees the Ethernet link drop, but still sees about -8 dBm light. Bouncing the port on the switch does not recover, but power cycling the 450m does. This AP ran without any issues for about 4 months prior. We have 1 other 450m’s with the exact same setup not having any issues.
We have the 450m and the AP set for auto-negotiation. Wondering if we should lock to 1G.
