The HPE Networking Instant On Access Points AP22D is the more versatile version of the AP22. It has the same antenna array and spatial streams (2x2:2) but has a 2.5GbE uplink port and four 1GbE downlink ports for hardwired devices. The AP22D can also supply Power over Ethernet (PoE) to two of the downlink ports at 15W (PoE 802.3af) when powered with Class 6 PoE 802.3bt or the optional DC power supply. When powered by Class 4 PoE 802.3at, the AP22D will supply power to one port at 15W (PoE 802.3af). This makes the AP22D great for IP phones or receipt printers in areas that need more Ethernet ports and only one in-room Ethernet port is available. Great for boutique hotel rooms, home offices, or reception areas.
