Three-port PoE passthrough switch

The NETGEAR ProSafe EXT-102GAF is a compact unmanaged switch with three Gigabit RJ45 ports. One port accepts IEEE 802.3 af/at PoE input up to 30 W while the other two deliver PoE output to devices such as access points or cameras. It operates plug-and-play with no configuration required.

Power-mode flexibility

The unit can be powered by PoE or by an external DC supply (not included). With 12 V 0.5 A DC input it functions as a network extender; with 37–57 V 0.5 A DC input it operates as a PoE switch. A dial switch enables port isolation for traffic separation.

12 Gbps total bandwidth

The switching fabric provides 12 Gbps aggregate throughput and supports 9216-byte jumbo frames. Buyers needing more than three powered ports or passive 24 V PoE compatibility should look elsewhere.

Questions about this item

Will the RJ45 ports need any maintenance or replacement over time?

The three RJ45 ports are passive copper interfaces with no moving parts or field-replaceable components, so no scheduled maintenance is required.

What throughput limit appears first when both PoE output ports run at full 30 W continuously?

The 1000 megabits per second packet forwarding rate caps total switched traffic before the 30 W per-port PoE budget is reached.

How much heat and noise does the metal case produce when powered by DC 37-57 V and passing 30 W to two devices all day?

The fanless metal enclosure relies on passive convection; it runs silent and stays warm to the touch but within normal operating temperature for unmanaged switches.
