Mikrotik CRS320-8P-8B-4S+RM

CRS320-8P-8B-4S+RM Cable management can get really exhausting. But it doesn’t have to. Our first PoE++ or 802.3bt switch can make your cable management so much easier, as it can output enough power for all your hotel, conference hall, office and high-rise building needs!

4K security cameras with built-in winter heating elements, LED ad screens, PoE-powered light fixtures – CRS320 can output up to 90W per port, enough even for the most demanding devices! It comes with a reliable 600 W power supply, but we’ve reserved an expansion slot for an additional PSU, in case you need to raise the power output to 1150 W.

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.

Unlike our previous 802.3af/at Power Sourcing Equipment, this is our first PoE switch with full implementation of the 802.3af/at/bt standard. It supports only fully compliant 802.3 at/af/bt Powered Devices – mAP-lite / RB1100AHx4 / CRS510-8XS-2XQ / CRS504-4XQ / FTC11XG / CRS305-1G-4S+OUT. While it can also power “802.3af/at/bt-compatible” Powered Devices, you must avoid specific grounding scenarios. Please refer to the official Help page. .

A hot-swappable PSU is included.
