Product Information

Overview

The MikroTik CRS112-8P-4S-IN is a compact managed switch with eight Gigabit Ethernet PoE-out ports and four Gigabit SFP ports. It combines copper access connections, fiber uplinks, and power delivery for compatible access points, IP cameras, phones, and other network devices.

All eight Ethernet ports support passive PoE or auto-sensing IEEE 802.3af/at output when powered by the appropriate supply. The included 28V, 3.4A adapter supports compatible low-voltage passive PoE devices. Powering IEEE 802.3af/at devices requires a separate 48–57V supply connected to the high-voltage DC input.

RouterOS Level 5 provides VLAN configuration, port isolation, traffic monitoring, access controls, and routing functionality. The fanless enclosure suits quiet offices and desktop installations, while included rackmount accessories provide additional mounting flexibility. SFP modules are sold separately.

Ideal Applications

  • Small office and branch access switching
  • Powering compatible wireless access points, IP cameras, and phones
  • Networks combining Gigabit copper connections and fiber uplinks
  • VLAN segmentation and traffic monitoring in network labs
  • Quiet indoor deployments requiring fanless operation
