FAQs

Q: How many powered endpoints can this micro switch support?
A: It provides 4x PoE+ (802.3at) access ports. The number of powered endpoints depends on each device’s draw and the available PoE budget from the power source.

Q: Which SFP modules are compatible for the uplinks?
A: Standard 1G SFP optics such as 1000BASE-SX for short-range multimode and 1000BASE-LX for single-mode long reach are supported. Use vendor-supported 1G SFPs for best results.

Q: Is the unit fanless for quiet rooms?
A: Yes, it is passively cooled and silent, ideal for offices, classrooms, and hospitality rooms.

Q: Does it provide Layer 3 routing?
A: It is an L2-managed access switch focused on VLAN, security, and QoS at the edge.

Q: Can it be installed in a wall duct?
A: Yes. Use the dedicated mounting box for OBO Bettermann ducts (sold separately).
