MERCUSYS MS105GP 5-Port Gigabit PoE+ Switch

The MERCUSYS MS105GP is a five-port Gigabit Ethernet switch with four PoE+ ports and a 65 W total PoE budget. Its claimed 250 m Extend Mode can help with longer cable runs, but reduces port speed to 10 Mbps, so it suits distance-sensitive PoE setups rather than full-speed links in that mode.

At a glance

Five Gigabit ports, including four PoE+ ports for compatible powered devices.
Each PoE+ port supports up to 30 W, with a stated total PoE budget of 65 W.
Extend Mode is claimed to reach 250 m, with port speed reduced to 10 Mbps.
One-click isolation mode is described for ports 1–4.
Metal casing and plug-and-play operation are listed.

Pros and cons

Pros

Four PoE+ ports can supply power and data to compatible devices over Ethernet, reducing the need for separate device power connections.
All five ports are listed as Gigabit-capable for standard operation.
Isolation mode provides a simple way to separate traffic on ports 1–4.
The metal casing and listed compact dimensions suit a small desktop network installation.

Cons

Extend Mode reduces port speed to 10 Mbps, which is a substantial trade-off for devices that need faster data transfers.

What to know before buying

The 250 m distance is a manufacturer claim for Extend Mode, not standard-speed operation. Actual range may vary with cable quality and powered-device consumption. The stated PoE budget is based on laboratory calculations and may vary with client limitations and environmental factors.

Listing details to confirm

Listing details are inconsistent or unconfirmed: the switch type field says “PoE/Non-PoE, Managed/Unmanaged” while the feature copy describes plug-and-play operation without clearly establishing management capability. The claimed kit highlights mention a metal case but the explicit contents list names only MS105GP, so any additional bundled items are uncertain.

Who is it for?

A good fit for

Small home or office networks needing several Gigabit Ethernet connections and PoE for compatible devices.
Installations using up to four 802.3af/at-compatible powered devices within the stated PoE budget.
Buyers who can use Extend Mode for longer PoE cable runs and accept its 10 Mbps port speed.

Less suited to

Devices or links that need more than 10 Mbps while operating in Extend Mode.
Setups needing more than five Ethernet ports or a PoE budget above the listed 65 W.

Customer feedback highlights easy plug-and-play use, reported Gigabit speeds, compact size and compatibility with home networks. Some customers also report failures within 18 months, and connectivity experiences are mixed. For a small wired setup, the reported ease of use aligns with the listed plug-and-play claim, but the mixed reliability feedback is relevant for installations where uninterrupted operation matters.

Positive themes

Customers report easy plug-and-play setup and useful Gigabit performance.
Compact size and home-network compatibility are cited as positives.

Negative themes

Some customers report failures within 18 months.

Mixed feedback

Connectivity performance and reliability receive mixed feedback.

Frequently asked questions

How many ports provide PoE+?

The listing specifies four PoE+ ports and five ports in total. It states a maximum of 30 W per PoE+ port and a 65 W total PoE budget.

Does the switch maintain Gigabit speeds over a 250 m run?

No. The listing says the 250 m Extend Mode reduces port speed to 10 Mbps. Actual distance may also vary with cable quality and the powered device.

What powered devices does it support?

The listing says it works with IEEE 802.3af/at-compliant powered devices. Check that the connected devices' power requirements fit the per-port limit and total budget.

Is this switch managed?

The listing's switch-type field gives both managed and unmanaged wording, while the features describe plug-and-play use. Management capability is not clearly confirmed, so verify the selected listing details if this matters.
