Hello Armin


Here a copy from the data sheet:

(http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6406/product_data_sheet0900aecd80322c0c.html)

The Cisco Catalyst 2960-8TT-L has eight 10/100 ports with one 10/100/1000 POE INPUT PORT. This switch does not need a power supply and receives power over the uplink from an upstream PoE device, providing deployment flexibility and availability. It is ideal for wiring and space-constraint applications. The power adaptor (PWR-A=) and power cord are optional and may be ordered separately.


This mean this particular switch can run without an AC power supply and take his power from other switch how can serving PoE as output

Also the eight 10/100 ports give NO PoE out.

So you need a different switch how is able to deliver PoE out.

HTH
