HP IntelliJack Gigabit switches are compact 10/100/1000 switches that can be installed in a standard wall outlet box, quickly converting an existing single-port LAN wall outlet into four switched Gigabit Ethernet ports. These "network jacks" provide a simple solution for adding network ports without running more cabling. Unlike conventional desktop switches, HP IntelliJack devices reside out of the way-literally in-the-wall-and so are more secure from theft and difficult to accidentally disconnect or damage. The innovative HP IntelliJack switches provide four Ethernet ports for local connectivity plus one uplink port. Two additional RJ-45 "pass-through ports" flexibly support a range of additional service and user connectivity options. It can be powered locally or via Power over Ethernet (PoE), and can output standard PoE on up to two ports to directly power attached devices such as IP phones or wireless access points.
