I am running a QU32 with an AB168 at FoH. From the AB168, I have a Cisco SG300-10P that is used as the distribution panel for my 8 ME-1 units that our musicians are using.
With no configuration, the “Expander” port on the AB168 shows a solid red light when connected into this Cisco switch. Based on other threads, I have disabled CDP and LLDP, rebooted the switch, and the port is still solid red with the LED.
Does anyone have a step-by-step guide for programming the Cisco SG300, or at least a general how-to for utilizing a managed switch (or turning off the managed portion) to power my ME-1 units.
Everything is A&H. This is for our church, so cost was a major factor. The Cisco is a managed switch, and I’m wondering removing the “managed” portion would correct the issue.
I am having the same issue. I have a A&H QU16, a single A&H AB168 and a Cisco SG350-10P switch. I have tried a VLAN and all other recommendations. I assume the LED on the expansion port should be lit green when it is happy? Can anyone offer insight into this…
But as the switch you are using is managed, you will need to turn off all layer 3 functions to force it to layer 2. Also, you will need to force the ports to run at Fast Ethernet (100BASE-TX).
If doing the above doesn’t solve the problem, you may need to use an unmanaged Fast Ethernet switch instead.
