This is an 8 port switch, with 4 PoE ports. It feels solid and well made - I often take one with me for demoing equipment and working at customer sites, and I can just chuck it in a bag without worrying as much as with more "plasticy" switches.
It has an external power supply, which uses a standard IEC (kettle) lead - another bonus when you're searching for cables. Beware that this is a 48V power supply, but the DC connector is the same size as many 12V supplies; one of our sales guys accidentally used the power supply from this switch with another piece of equipment and fried the circuit board.
Other than that, it's a standard 100MBps 8-port switch.
