This is the NSE-1 module from a Cisco 7206 VXR router.
The router was a surplus item from the local community college. It contained the NSE-1, the Fast Ethernet Input/Output module and two power supplies. It was powered up and checked for error lights before disassembly. No other knowledge about the router.
The board will be wrapped in anti-static bubble wrap then protected in a well packed box.
Usually ships next day.
