We just bought a 2960-C PD 8PT switch.
The switch is delivered without powersupply. It is supposed to get power from a PoE port on another switch.
When I connect the Gigabit 1 or 2 port on the 2960-C to a PoE port on my 4507 switch the 2960-C switch starts the booting process.
After some time in the boot process:
The password-recovery mechanism is enabled.
64K bytes of flash-simulated non-volatile configuration memory.
Base ethernet MAC Address : F8:4F:57:35:8A:80
Motherboard assembly number : 73-12988-05
Motherboard serial number : FOC17243149
Model revision number : B0
Motherboard revision number : B0
Model number : WS-C2960CPD-8PT-L
System serial number : FOC1725Y0FM
Top Assembly Part Number : 800-33532-01
Top Assembly Revision Number : D0
Version ID : V01
CLEI Code Number : CMMDT00ARA

Switch Ports Model SW Version SW Image

* 1 10 WS-C2960CPD-8PT-L 12.2(55)EX2 C2960c405-UNIVERSALK9-M
then the 4507 port is error-disable and shuts down its port - and then the 2960-C is shut down.
After some time the 4507 enables the port again, and the 2960-C starts rebooting again...
Does anyone have an idea of how to fix this??

After some time the 4507 enables the port again, and the 2960-C starts rebooting again.
This sounds like someones configured BPDUGuard as well as error-disable recovery.
Can you post the output to the command "sh run | i recovery"?
