Common FAQs

Can the CRS112-8G-4S-IN power other PoE devices?
No, it only supports Passive PoE-In, not PoE-Out. It’s designed to be powered via Ethernet, not to power other devices.

What SFP modules are compatible?
The SFP ports support 1Gbps SFP modules (fiber or copper) for high-speed uplinks.

Can I use this outdoors?
It supports wide temperature ranges, but for direct outdoor use, you’ll need a weatherproof enclosure.

Is this device manageable remotely?
Yes, using RouterOS via WinBox, WebFig, SSH, or API — it supports full remote management.
