Ultipower PoE 4-Way High Power 803.3

The ULTIPOWER ULTIPOE4-HD PoE switch is a desktop device enabling smooth data transmission in 10/100 Mbps Ethernet networks. Its five RJ45 ports support auto-negotiation function, four of them provide power over Ethernet (PoE function). The switch automatically detects PD devices compliant with IEEE 802.3at standard and provides them with power supply. This feature allows the user to expand the network coverage in areas where there is no access to AC power lines/outlets and to deploy access points, IP cameras, IP phones, etc.

Key features:

• Total of five 10/100 Mbps ports
• 4x PoE port (each of them ensuring communication and power supply for a network device via a single UTP cable)
• No need for installation or configuration
• Max capacity of each PoE port: 25.5 W
• Support for (PD) PoE devices compliant with IEEE802.3at standard
• Support for auto-learning and auto-aging of MAC addresses
• LED indicators providing information on status/speed/activity/PoE

802.3af vs. 802.3at

The most popular PoE standard, 802.3af, is used e.g. by IP cameras. The supplying voltage can vary from 44 to 57 VDC and the consumed power cannot exceed 15.4 W. The 802.3at version allows for powering devices with DC voltage within 50...57 V range, which consume up to 25.5 W. This group of devices includes printers, IP PTZ cameras, switches.
