THE IB-PL500D
Just by looking at them you can see that the IB-PL550D Powerline adapters by RaidSonic are quite small (each adapter uses less than 1W in idle and less that 5W during use).
To see just how small they are i placed one of them right next to the latest TPL-402E 500Mbit/s Powerline adapter by TRENDnet.
The holes of the power outlet feature the typical protection system.
Three activity LEDs are placed at the lower front, the power on LED, Ethernet LED and the connection LED.
Each adapter is perforated on all sides (especially during the summer period these adapters can get really hot).
A small reset button is placed on the right side.
At the bottom of the adapter we see the RJ45 Ethernet port and the lock button.
You can find the units default MAC address along with its serial number and electrical specifications on a small sticker placed at the rear.
