MikroTik CRS328-24P-4S+RM: 24-Port Gigabit Router/Switch with PoE

The MikroTik CRS328-24P-4S+RM is a versatile and powerful Layer 3 router/switch, offering 24 Gigabit Ethernet ports with PoE-out and 4 SFP+ ports for high-speed uplinks. This 1U rackmount device is designed for businesses and enterprises needing robust networking solutions with advanced PoE capabilities and high bandwidth for fiber or Ethernet uplinks.

Product Features

• Powerful PoE-Out Options: Supports Passive PoE, low voltage PoE, and 802.3af/at (PoE/PoE+), with automatic power sensing for connected devices.
• 24 Ethernet Ports: Provide up to 30 W of power per port, with a total PoE budget of 450 W (split into three 150 W groups).
• 4 SFP+ Ports: Deliver up to 10 Gbps uplinks via optical fiber or Ethernet modules (not included).
• Dual Operating Systems: Choose between RouterOS (for Layer 3 features) or SwOS (for a simplified switch-focused experience).
• High Power Capacity: Comes with a built-in 500 W AC power supply and supports an extensive range of PoE devices.
