In my previous post, I talked about the TL-SG1008PE, an 8-port Gigabit POE switch. If you need a cheaper alternative, take a look at the TP-LINK TL-SG1008P 4-Port Gigabit PoE Switch. It essentially the same switch, but it only has 4 POE ports instead of 8. It will support IEEE 802.3af compliant powered devices. Notice it’s 802.3af only. It doesn’t support 802.3at. This PoE switch currently sells for $80 at Amazon.
