# 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

- 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.

## Before you buy

- 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 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.

## In the box

- MERCUSYS MS105GP switch (Included)
- Case (Check selected pack): The listing highlights mention a metal case, but the explicit contents list names only the MS105GP.

## 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

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.
- Positive themes: 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.
