The Presonus SW5E is a five-port AVB switch. Four of the ports can provide power over Ethernet (pole) for pole-compatible devices, while the fifth port is non-pole, which is useful for linking to additional switches. Housed in a rugged, all-metal chassis, it can be rack mounted using a rack tray (not included). all ports employ secure, rugged ethercon jacks, making the SW5E a great choice for live sound systems.
