CRS320-8P-8B-4S+RM: tame the cables, power everything

Cable chaos doesn’t have to be part of the job. CRS320-8P-8B-4S+RM is our first PoE++ (802.3bt) switch, built to simplify wiring in hotels, conference venues, offices, and high-rise deployments by delivering serious power right over Ethernet.

Power that keeps up

Think 4K security cameras with built-in heaters, LED signage, even PoE lighting—this switch can feed them all with up to 90 W per port. It ships with a reliable 600 W PSU, and there’s an expansion bay if you want to boost the total to ~1150 W.

The right ports in the right places

• 17× Gigabit Ethernet total
  • Ports 1–8: 802.3af/at PoE-out
  • Ports 9–16: 802.3bt PoE++
  • +1× dedicated Gigabit management port
• 4× SFP+ (10G) uplinks for fast fiber aggregation
• Console port for quick, direct access

Performance you can trust

At the heart is a proven Marvell switch chip (as used in ISP favorites like netPower 16P and netFiber 9). It chews through heavy workloads, including VLAN filtering and hardware-offloaded Layer-3 routing.

Clean installs, cleaner racks

Trade the tangle of DC bricks for a single, centralized PoE source. With one CRS320, you can standardize power and data across floors and buildings—the minimalist PoE dream.

Standards & compatibility notes

This is our first switch with full 802.3af/at/bt PSE implementation. It supports fully compliant 802.3af/at/bt PDs, including:
mAP-lite / RB1100AHx4 / CRS510-8XS-2XQ / CRS504-4XQ / FTC11XG / CRS305-1G-4S+OUT.
It can also power “802.3af/at/bt-compatible” devices, but avoid certain grounding scenarios—please see the official Help page for details.

Serviceability

A hot-swappable PSU is included for easy maintenance and maximum uptime.

Bottom line: one switch, massive PoE headroom, flexible uplinks, and ISP-grade silicon—CRS320 turns messy cable plants into tidy, scalable networks.
