16-port PoE+ managed switch with 4 SFP combo ports

The PLANET GS-4210-16P4C provides sixteen 10/100/1000BASE-T RJ45 ports with IEEE 802.3at PoE+ support and four shared 100/1000BASE-X SFP slots. It delivers up to 30.8 watts per PoE port within a 220-watt power budget. The switch is managed and supports LACP, VLAN tagging, and IGMP snooping for segmented networks.

Who this suits and who should look elsewhere

This switch fits installers powering IP cameras, wireless access points, or VoIP phones over copper while uplinking via fibre SFP modules. It is not for deployments needing more than sixteen powered ports, 10-gigabit uplinks, or a PoE budget above 220 watts. Buyers requiring unmanaged simplicity or fanless silent operation should consider other models.

220-watt PoE budget determines device count

The total PoE power budget of 220 watts limits how many 30.8-watt class 4 devices can run simultaneously. Calculate the aggregate draw of all powered endpoints before purchase to ensure the budget covers every connected device. Exceeding this limit will cause ports to shut down or devices to fail.

Questions about this item

How much heat does the 251-watt maximum dissipation add to a rack running all day?

At full load the switch dissipates 861.2 BTU per hour, so plan rack airflow for that continuous thermal output.

Which SFP modules must I already own to use the four combo uplinks?

The four shared slots accept 100/1000BASE-X mini-GBIC or SFP transceivers, including 100BASE-FX variants, for fiber uplinks.

Will my older 10/100 devices slow down the 10/100/1000BASE-T ports?

Each RJ45 port auto-negotiates to 10, 100 or 1000 Mbps, so legacy gear runs at its rated speed without degrading gigabit links.
