Hi Don,

Saw a very interesting phenomena today on my SG300 switch.

Noticed in the hyperterminal console, that there is a option to put the SG300 in Layer 3 mode, so I did. Thought I would give it a try.

After doing that I again setup tagged VLAN for vlan 100 (uc520-voice) , because the unit factory defaulted…ok SG300 said it would do that…so ok.

But I noticed that my POE devices would not come up…I have the log below, but it shows nothing,

See the first screen shot, it shows max power available at 1W.

OK, thought then to default my machine and reboot. POE power was still gone.

I unplugged the power cable and after the reboot POE power was restored, see second screen capture below.

( My guess- Seems to me that something like a register may have got stuck off, and a removal of power initialized the registers.)

Otherwise all has been stable over the last week. No other problems observed.

I did think these units could go into cli mode, what is the new command to go into CLI mode?

Regards Dave

I will see if I can replicate this.

The command for entering the CLI is available in the FAQ:

1. How do I access the command line mode?

-    Log on to the console as normal with the configured user name and password
-    Type ‘ctrl-z + 4’
-    Type ‘lcli’
-    Enter the same user name and password

To get out of cli mode
- Type ‘debug-mode’
- Type ‘menu’

I was able to recreate the issue, but only one time. Following your steps above, it happened the first time, but every attempt since then, I have been unable to recreate it.

The attached screenshot shows the max power 1w and used 0 when it should be 125 and 5. The POE device would not turn on.
