Hi all,
I got a Cisco 2960-S LAN (support PoE+) switch installed in one of my customers' office. The customer needs to plug some cameras to the switch and need inline power from the swtich.
Two of the cameras requires 24W power in order to work correctly, if just use normal PoE power, can't get all functions working and get an error message on the screen says "not enough power" or something like that. I have configured those two port to static power inline (on a max value which is 30W). Once the configuration applied, shut/ no shut the port, the error message disappeares for a few minutes, and then comes back. Looks like the power level is still on PoE not PoE+.
Is there anything I can do on the configuration to increase the inline power and provide a stable power to that kind of devices?
