DS1018GMP Is an 18-port Gigabit Desktop / Rackmount Switch with 16 PoE+ ports. It provides a simple way to expand a wired network by transferring power and data over a single Ethernet Cable. Compliant with the IEEE 802.3af/at PoE standards, the switch supports a total PoE power budget of 250W with 30W max per PoE+ port. When total power consumption exceeds 250W, the intelligent power management will cut the lower priority ports power to protect devices from damage.
