Take a look at the three pictures immediately below. Note that there's a standard Ethernet socket at the base of the adaptor. This is its only connector, apart from the integrated three-pin plug that goes into a mains socket and, in effect connects the adaptor to your new network - the ring mains in your house!

green LEDs - and explain their functions below
The three left-hand LEDs are:
100/Act - this is lit whenever an Ethernet connection exists and flashes to signal 100Mbps data rate.
10/Act - this is lit whenever an Ethernet connection exists and flashes to signal 10 Mbps data rate.
Col (collision detection) - this flashes at a faster rate as the network is experiencing increasing use and is intended to show if there's too much network traffic.
The three right-hand LEDs are:
Power - this is lit when the adaptor is ready for action.
Act - this flashes when data is being sent or received over the power lines.
Link - this is lit if the adaptor is connected as a part of a dLAN network.

But what do you get, as well as the two adaptors? Well, there's that pair of previously-mentioned Ethernet cables (each 3m in length); a double-sided A4-size quick-start guide; a 26-page sub-A4 printed manual; and a CD.
The CD contain a PDF version of the manual (in Dutch, English, French, German, Italian, Spanish); four self-installing Windows programs; some apps for Mac and Linux; and - for those who don't like reading - two six-minute instructional videos, one in English, the other German.
Okay, that's more than enough preamble, let's get hands on.
