Small rectangular network switch with two Ethernet ports

Monoprice Inc. 011187 2-Port PoE Gigabit network switch

SKU CH-4Z5M-GB1DV

A compact 2-port Gigabit switch that splits one PoE uplink into two powered ports, drawing 802.3 power from the upstream link

  • Powered by incoming PoE so no extra outlet needed
  • Single 802.3at or 802.3af uplink feeds the unit
  • One upstream link becomes one or two downstream ports
  • Both downstream ports deliver PoE to connected devices
  • Compact two-port design fits tight enclosures

Expand a single PoE link

The CyberData 2-Port PoE Gigabit switch takes one powered network connection and splits it into one or two downstream ports. It draws its operating power from the upstream link using 802.3at or 802.3af standards and passes that power through to connected devices. Network installers and integrators can add PoE endpoints without running new power cabling.

Replaces extra injector runs

Instead of deploying separate midspan injectors or a larger multi-port switch for a small cluster, this unit adds ports exactly where they are needed. The jump is worth it when only one or two devices such as cameras or access points must be powered from a single existing PoE feed. It avoids the cost and complexity of a full switch upgrade for minimal port growth.

Fits inline with existing infrastructure

The switch sits between an 802.3at or 802.3af source and up to two powered devices, requiring no local AC outlet. It frees up space in cabinets or enclosures by eliminating external power supplies for the added ports. Builders planning larger expansions should note the two-port limit and plan upstream capacity accordingly.

Questions about this item

Does the 011187 switch need a separate power adapter or does it draw power from the upstream 802.3 connection?

It draws power from a single 802.3at or 802.3af upstream switch and passes that power to its two downstream ports, so no separate adapter is required.

How do I connect the 011187 so both downstream devices receive PoE without losing the uplink?

Plug the uplink into the PoE-in port; the switch then splits the connection and power to the two PoE-out ports — the step often missed is verifying the upstream port is 802.3at or 802.3af compliant.

When will the 011187 need maintenance or replacement if it runs continuously?

With no moving parts or internal power supply, it typically runs until the upstream PoE source fails or network standards change; no scheduled maintenance is required.
