Hi,
I recently purchased a CRS305 switch with the intention of going 10GbE for part of my network (server, NAS and main desktop). To that end, everything works great!
I have one hiccup with the setup. My intention is to use the 1GbE port on the CRS305 as an uplink and PoE power to an upstream Ubiquiti US-8-60W switch. Initially, when I first received the CRS305 and set it all up last week, everything worked just fine. I had the CRS305 plugged into port 5 of the US-8-60W (ports 5-8 are PoE capable). The only PoE device attached to the US-8-60W is an Ubiquiti AP (UniFi HD) which is connected to port 8. I am using SwitchOS. Both switches have the latest firmware.
Recently, I unplugged the devices to do some cable management and upon re-plugging everything back in (same setup as before), the CRS305 will not power on via PoE from the US-8-60W. I tried rebooting the US-8-60W, trying different ports and different cables (Cat5e and Cat6a) to no avail. Obviously, the switch powers on and works just fine using the AC adapter. It will also work using a Ubiquiti PoE injector (48V, 0.5A)...but not the US-8-60W.
I am at a lost as to why it initially worked, but will not anymore. Any one have any ideas?
Thanks!
