Five 2.5GbE ports plus 10G SFP+

This unmanaged switch provides five 2.5Gbps RJ45 ports and one 10Gbps SFP+ uplink for multigigabit wired networking. It suits NAS, gaming consoles, PCs and workstations that need more bandwidth than standard gigabit links. Auto-negotiation handles 10M, 100M, 1G and 2.5G speeds automatically.

Fanless aluminium chassis keeps it silent

The full aluminium alloy housing dissipates up to 12 watts of heat without any fans or moving parts. Power draw is 1 amp at 12 volts from the internal AC 120/230 V supply. Silent operation makes it suitable for home offices, entertainment centres or any quiet environment.

SFP+ module sold separately adds fibre

The 10Gbps SFP+ port accepts 1G, 2.5G or 10G optical and copper modules that must be purchased separately. No bundled software or management features are included; the switch is purely plug-and-play. Buyers who need PoE power or Layer 2 management must look elsewhere.

Questions about this item

How do I install the NUBASA 5-port 2.5Gb switch and what step do people often miss?

Connect the AC power cord to a 120/230 V outlet, then plug devices into the five 2.5G RJ45 ports and the 10G SFP+ uplink; the step often missed is inserting a compatible 1G/2.5G/10G SFP+ module (sold separately) into the uplink port before linking to a router or NAS.

What maintenance or replacement will this switch need later?

The fanless aluminum chassis has no moving parts to service; only the SFP+ transceiver module may need replacement if you change link speed or media type, and the unit itself requires no scheduled maintenance.

What limit appears first under sustained heavy traffic?

The 768 KB buffer memory and 45 Gbps switching capacity set the practical ceiling; once aggregate throughput exceeds that capacity or bursts fill the buffer, latency rises before any thermal throttle engages.
