OK,

but how i configure?

I made a test configuring wich that command

"power inline negotiation injector H.H.H" and don't work!

without more information, it is difficult to say what's wrong, that's why I suggest you to do the troubleshooting according to the TS Guide step by step.

Basicly the TS could be summarized as following steps:

1. Check your cable connection:

*ethernet cable is connected to AP's ethernet port not console port

*AP is connected to Power Injector's AP port, Switch is connected to Power Injector's switch port.

2. Check AP's LED and Power Injector's LED(table 3-1 and 3-2 of the TS guide show the different result)

3. Check switch's port configuration(CDP, duplex, etc)

4. Check power configuration(refer to table 3-3~6, figure 3-3)

5. Check error logs( connect to AP's console port to see if there's any error/warning mesg)

when the AP IOS boot i receive this message "CDP_PD-4-POWER_OK: Full power - INJECTOR_DETECTED inline power source" the bv1 interface change to up and than change to down.

AP led status is green and the others are off.

The CDP protocol is enable.

I think the problem is betwen the power injector and the switch C2960G.

Any idea??

thanks
