Simple PoE for a few cameras.
Ports 1 to 8 each supply up to 30 W of 802.3af/at PoE+, sharing 65 W between them. Ports 9 and 10 carry data only and suit the router or recorder. Switches on the back turn on Extend, Isolation and PoE Auto Recovery, and ports 1 and 2 always get priority when the network is busy.

Front panel
8 PoE+ ports and two uplinks.
Ports 1 to 8 supply PoE+, and ports 1 and 2 are the priority ports for your most important cameras. Ports 9 and 10 are for the router or recorder. Each port has a Link/Act light and each PoE port a PoE light.

Rear panel
Three switches, no software.
Recovery and Isolation work on ports 1 to 8. Extend has three positions: off, on for ports 1 to 4, or on for ports 1 to 8. Beside them are the 53.5 V DC power socket, the Power light and a security slot.
How it goes in
From box to powered cameras.
01
Place it
Fit the rubber feet and stand it on a desk or shelf, bottom side down, between 0 °C and 40 °C.
02
Set the switches
On the back, turn on Extend for runs past 100 m, Isolation to keep ports 1 to 8 apart, and Recovery to reboot frozen devices.
03
Connect
Plug the router or recorder into port 9 or 10, then cameras, phones and access points into ports 1 to 8, key cameras on 1 and 2.
04
Power and check
Plug in the power adapter. The Power light comes on and each powered device lights its PoE light. Keep the total under 65 W.

What this switch works with
Cameras
PoE IP cameras
802.3af/at cameras such as TP-Link VIGI. Add up your cameras' power draw and keep it under the 65 W budget.
Recorder
An NVR on port 9 or 10
Uplink the recorder or router to a non-PoE port, so it keeps working when Isolation is on.
Faster option
TP-Link DS110GMP
Gigabit ports, a 123 W budget and an SFP uplink, for busier cameras or Wi-Fi access points.
Cabling
Cat5e or Cat6 cable
Up to 100 m per run, or 250 m with Extend mode on.
Where it is used
Where a small 10/100 PoE switch fits.
Home CCTV
Four to eight cameras feeding a recorder, powered over their network cables.
Small shops
A few cameras and a desk phone from one quiet box under the counter.
VoIP phones
Desk phones powered over the network, no plug packs at each desk.
Sheds and outbuildings
Extend mode reaches 250 m to cameras at the far end of a property.
Farm and gate cameras
PoE Auto Recovery reboots a camera that freezes, without a site visit.
Shared spaces
Isolation keeps the connected devices apart, each one only reaching the uplink.

Common questions
How much PoE power does the MS110P have?
65 W in total across ports 1 to 8, with up to 30 W on any one port. It works with IEEE 802.3af/at powered devices.
Is it gigabit?
No. All ten ports run at 10/100 Mbps, up to 100 Mbps each. For gigabit ports, look at the TP-Link DS110GMP.
Which ports supply PoE?
Ports 1 to 8. Ports 9 and 10 are data-only and are meant for the router or recorder.
What happens if I go over 65 W?
Lower-numbered ports win. The switch cuts power to the highest-numbered PoE port to keep the others running.
What does Extend mode do?
It runs PoE and data up to 250 m at 10 Mbps. The rear switch turns it on for ports 1 to 4 or for ports 1 to 8.
What does Isolation mode do?
Ports 1 to 8 can no longer talk to each other, only to ports 9 and 10. Plug the router or recorder into 9 or 10.
What is PoE Auto Recovery?
The switch watches devices on ports 1 to 8 and reboots one that stops responding. Turn it off while you update a camera's firmware.
What are the priority ports?
Ports 1 and 2 send their traffic first when the network is busy, so put your key cameras there.
Is it managed?
No. It is plug and play with no web page or VLANs. The three switches on the back are the only settings.
Is the power supply included?
Yes. Mercusys lists a power adapter in the box: 100–240 V AC in, 53.5 V DC 1.31 A out.
Who makes the MS110P?
Mercusys, a networking brand owned by TP-Link. The MS110P is made and supported under the Mercusys name, and the figures on this page come from the Mercusys datasheet.
Who can install the cable?
Concealed data cabling to cameras and outlets is customer cabling under AS/CA S009 and needs an ACMA-registered cabler.
Supported by InFront Technologies.

Installation and safety
Mains powered. The switch runs from its plug-in power adapter. Keep the adapter near the switch and the power point easy to reach. A new power point needs a licensed electrician.
Cabling. Concealed data cabling is customer cabling under AS/CA S009 and needs an ACMA-registered cabler. Outdoor runs need outdoor-rated cable.
Indoor use. Keep it dry, out of direct heat and within 0 °C to 40 °C. The PoE ports must not be used to charge lithium batteries.
What it does not do. No gigabit ports, no SFP, no VLANs or web management, and no 802.3bt PoE++.
