There are 17 Gigabit Ethernet ports: #1-#8 Gigabit Ethernet ports with 802.3af/at PoE-out, #9 – #16 802.3bt PoE++ ports, and an extra Gigabit Ethernet port for management purposes. There’s also a console port, and four 10G SFP+ fiber ports for uplink. At its core, this convenient switch has a phenomenal Marvel switch-chip – the same one you’ve seen in ISP bestsellers like the netPower 16P and netFiber 9! It can handle the heaviest loads, including VLAN-filtering and hardware-offloaded Layer-3 routing. If you’ve been looking for a way to simplify your cable management – this is it! With a single CRS320, you can ditch that endless mess of DC power adapters and start living the clean minimalist PoE dream.
