Pros & Cons

Pros

✓ 16 RJ45 ports at 2.5GbE plus 2 x 10G SFP+ uplinks in one box
✓ 120Gbps non-blocking switching capacity across all 18 ports
✓ Fanless design runs silent, fine for desks, closets and bedrooms
✓ IEEE 802.3bz ports auto-negotiate 10/100/1000M/2.5G for mixed gear
✓ Metal case with 4KV lightning protection; desk or wall mounting

Cons

✗ Unmanaged: no VLANs, QoS, link aggregation or port monitoring
✗ RJ45 ports top out at 2.5G; no 5G or 10G copper ports
✗ SFP+ modules or DAC cables are not listed as included
✗ No PoE listed, so WiFi 6 APs need separate power or injectors

Manufacturer description

The GigaPlus 18-port 2.5Gb unmanaged Ethernet switch gives your home lab or small office a multi-gig backbone without any configuration. It has 16 RJ45 ports that run at 100/1000/2500 Mbps and two 10G SFP+ uplink ports, all backed by 120Gbps of non-blocking switching capacity. Ports 1 to 16 follow the IEEE 802.3bz standard and auto-negotiate 10/100/1000M/2.5G. Your existing gigabit devices keep working, and 2.5GbE gear gets up to 2.5 times the throughput of a standard 1G network. Auto MDI/MDIX means any patch cable works. There is no software and no web interface to set up: plug in the…

SpecPicks Verdict

SpecPicks scored 18 Port 2.5Gb Unmanaged Ethernet Switch with 16* 2.5G Base-T Ports using a rating × review-volume × price-fit model applied to published specs and reviews across the networking category. GigaPlus's networking lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.

Common buyer scenarios for networking of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions

How many ports does the GigaPlus 18-port switch have, and how fast are they?

It has 18 ports. Ports 1 to 16 are RJ45 Ethernet ports supporting 100/1000/2500 Mbps, and the remaining two are 10G SFP+ uplink ports. Total switching capacity is 120Gbps, non-blocking.

Will my older 1Gbps devices work with this 2.5G switch?

Yes. Ports 1 to 16 comply with IEEE 802.3bz and auto-negotiate 10/100/1000M/2.5G, so gigabit PCs, consoles and routers connect at their native speed alongside 2.5G devices.

Do I need to configure anything or install software?

No. It is an unmanaged, plug-and-play switch with automatic MDI/MDIX. There is no setup and no software. Because it is unmanaged, it also has no VLAN or QoS settings.

What can I connect to the 10G SFP+ ports?

Use them as uplinks to a 10G NAS, server or core switch through SFP+ transceivers or DAC cables. The listing does not say whether modules are included, so check compatibility and the box contents on the product listing.

Is the switch noisy, and can it be wall mounted?

It is fanless, so it makes no fan noise. It uses a metal housing with 4KV lightning protection and supports both desktop and wall mounting.
