After reviewing dozens of 2.5GbE switches, our current top pick for unmanaged switches is the Gigaplus GP-S25-0802. Today we have the update to that switch, now with PoE+ capabilities. The Gigaplus GP-S25-0802P is still unmanaged, but it is also still a cheap switch. With eight 2.5GbE ports and two SFP+ 10GbE ports, it is one of the cheaper, higher-capacity 2.5GbE switches on the market. We purchased this switch for only $98, but it is usually $109 minus some discount.

If you just want to find the switch for purchase, here is an Amazon Affiliate link to the switch where we purchased the unit. Note that pricing may change and often does so daily.

This is one of the first 2.5GbE switches we have covered since our big 2024 Mega round-up, which you can find here:

We have also added this switch to the Ultimate Cheap Fanless 2.5GbE Switch Buyer’s Guide where we have now listed 50+ models. Bookmark that page to get the latest. We will like all of these reviews from that page.

The front of this switch has eight 2.5GbE ports and two SFP+ ports. That second SFP+ port is really the big change here versus the 8+1 switches we have seen previously. We have several of the non-PoE versions at this point because that second SFP+ port is so useful.

This one has long rack ears, but they fit a standard 19″ rack.

If you saw our recent Hasivo S600WP-5XGT-1SX-SE review, that switch can be a better value in some cases if you need 10Gbase-T, but it did not have properly sized rack ears.

On the non-PoE version, we get a front power input. Inside, Gigaplus is doing something interesting. The eight 2.5GbE ports are PoE+ capable, but there is no clear indicator if PoE is active. Usually in cheap switches we get some kind of indicator on the ports. Not here.

The two SFP+ cages are at the other side.

The switch itself is still a desktop form factor so it is short depth and not even 1U height. We did not get rubber feet, but we would suggest getting rubber feet for this one if you are not rack mounting it.

On both sides, we get vents, but no fans.

The rear is a has the AC power input and a grounding point.

On the bottom, we get a label. There are some markings that we did not verify.

Inside the switch, we see some things that are similar, and others that are different from the non-PoE version.

Unfortunately, this is not the new MaxLinear solution, we have only found one low-production switch with that single-chip solution so far. The switch PCB is almost the same as the non-PoE version, but with some differences to accomodate the PoE feature.

This is V1.2 of the switch board whereas the non-PoE versions we have are all V1.1. In these switches, versions often change. Still, one big difference is that the power input is via a connector and there is an 8-port PoE board that is internally labeled as having no isolation.

We wanted to take the PoE board off, but it was glued in place on both sides.

The internal power supply is a Sirivision POE-150W model. This provides a 52V output common for PoE switches.

Next, let us get to performance and power consumption.
