• Compatible with Power-over-Ethernet (PoE)
• Rack-mountable with an optional 1U rack-shelf (sold separately)

Dualcomm ETAP-5203 is a gigabit copper Network TAP capable of simultaneously monitoring two 10/100/1000Base-T Ethernet links. ETAP-5203 stands out on the market as a failsafe GbE Network Tap without using a cooling fan due to its low-power design and several other unique features.

ETAP-5203 provides two copper inline link interfaces with two aggregation monitor ports. Each copper inline link interface consists of two RJ45 ports.

ETAP-5203 can operate in one of two operation modes: Dual-TAP Mode and Dual-Link Mode, which is manually pre-configured by a DIP switch. Power recycling is required to change the operation mode.

When the ETAP-5203 operates in the Dual-TAP Mode, it functions as two independent copper GbE Network TAPs, each of the two monitor ports outputs a copy of aggregated full-duplex traffic of the corresponding copper inline link.

When the ETAP-5203 operates in the Dual-Link Mode, each of the two monitor ports outputs a copy of aggregated full-duplex traffic of the two copper inline links.

One rare feature is that, in the Dual-Link Mode, any of the two monitor ports are stacking ports by which multiple ETAP-5203 units can be interconnected with one another to monitor more than two network links with any of the remaining monitor ports.

The two RJ45 ports of each copper inline link interface will fail over automatically to maintain link connectivity when ETAP-5203 loses power. As such, ETAP-5203 can be used for deployment in critical link paths in a network.

When a live link goes down on one RJ45 port of a copper inline link interface, the link on the other RJ45 port of the copper inline link interface will go down automatically. This feature is usually desirable or required for high availability deployment to reduce the time for activating a redundant link path in a network.

ETAP-5203 is compatible with Power-over-Ethernet (PoE), which is capable of passing PoE inline power between two RJ45 ports of a copper inline link interface. As such a connected PoE powered device (e.g., a PoE IP phone) can still receive the inline power from its PoE capable link partner such as a PoE switch.

ETAP-5203 can be rack-mounted with the optional mounting hardware kit (Model No. RMKIT-1000), which can be purchased separately.
