The MikroTik CRS328-24P-4S+RM is a 1U rackmount PoE switch with 24 Gigabit Ethernet ports with PoE-out and four 10G SFP+ ports.

Each Ethernet port can supply passive PoE, low-voltage PoE or 802.3af/at with auto-sensing, up to 30 W per port. The built-in 500 W supply leaves 450 W for PoE (150 W per group of 8 ports). It dual-boots RouterOS (level 5) or SwOS. SFP+ modules are not included.

Key features

  • 24 x 10/100/1000 Ethernet ports with PoE-out
  • 802.3af/at and passive PoE, up to 30 W per port
  • 450 W total PoE budget from the internal 100-240 V AC supply
  • 4 x SFP+ ports (10G)
  • Marvell 98DX3236 CPU at 800 MHz, 512 MB RAM
  • RJ45 serial console, 2 fans

In the box

  • K-54 kit
  • IEC power cord
  • Rack ears
