• ETAP-5203E: Supports Dual-TAP Mode and Single-TAP Mode which provides two non-aggregation monitor ports and two aggregation monitor ports.

• ETAP-5203BP: Supports Dual-TAP Mode and Bypass SW Mode which functions as a 10/100/1000Base-T Ethernet bypass switch with two aggregation monitor ports.

• Low-power, fanless design

• Power failsafe bypass

• Link Fault Pass-Through (LFPT)

• Power-over-Ethernet (PoE) pass-through

• Rack-mountable with an optional 1U rack-mount kit (sold separately)

The Dualcomm ETAP-5203 is a failsafe Gigabit copper network TAP capable of simultaneously monitoring two 10/100/1000Base-T Ethernet links. Its low-power, fanless design delivers quiet operation while supporting advanced traffic monitoring and network availability features.

The ETAP-5203 provides two copper inline link interfaces and two aggregation monitor ports. Each inline link interface consists of a pair of RJ45 ports.

The ETAP-5203 supports two operating modes—Dual-TAP Mode and Dual-Link Mode—selectable via a DIP switch. A power cycle is required for a mode change to take effect.

In Dual-TAP Mode, the ETAP-5203 functions as two independent Gigabit copper network TAPs. Each monitor port outputs a copy of the aggregated full-duplex traffic from its corresponding inline link.

In Dual-Link Mode, each monitor port outputs a copy of the combined full-duplex traffic from both inline links.

Dual-Link Mode also supports monitor port stacking. Either monitor port can serve as a stacking port, allowing multiple ETAP-5203 units to be interconnected to monitor more than two network links. The remaining monitor ports are available for traffic monitoring.

Power Failsafe Bypass

If the ETAP-5203 loses power, the two RJ45 ports of each inline link interface automatically switch to a bypass connection to maintain network connectivity. This failsafe capability makes the ETAP-5203 suitable for deployment in mission-critical network environments.

Link Fault Pass-Through (LFPT)

The ETAP-5203 supports Link Fault Pass-Through (LFPT). If the link on either RJ45 port of an inline link interface goes down, the link on the paired port is automatically brought down as well. This behavior helps connected network equipment detect link failures and activate a redundant network path more quickly.

Power-over-Ethernet (PoE) Pass-Through

The ETAP-5203 allows PoE power to pass transparently between the two RJ45 ports of each inline link interface. Connected PoE-powered devices, such as IP phones, can therefore continue to receive power from their PoE-capable link partners, such as PoE switches.

Rack Mounting

The ETAP-5203 can be rack-mounted using the optional RMKIT-1000 1U rack-mount kit, sold separately.

ETAP-5203E: Dual-TAP and Single-TAP Modes

The ETAP-5203E supports Dual-TAP Mode and Single-TAP Mode.

In Single-TAP Mode, the ETAP-5203E provides two non-aggregation monitor ports and two aggregation monitor ports. Each non-aggregation monitor port outputs traffic from one direction of the monitored link, allowing users to avoid monitor port oversubscription when bidirectional traffic is heavy.

The ETAP-5203E can also serve as a direct replacement for the ETAP-3105.

ETAP-5203BP: Dual-TAP and Bypass SW Modes

The ETAP-5203BP supports Dual-TAP Mode and Bypass SW Mode.

In Bypass SW Mode, the ETAP-5203BP functions as a 10/100/1000Base-T Ethernet bypass switch with two aggregation monitor ports. It is typically deployed with an inline network security appliance, such as an intrusion detection system (IDS) or intrusion prevention system (IPS).

If the ETAP-5203BP loses power, its two network ports automatically switch to a bypass connection to maintain network connectivity. The unit also monitors the links to the attached appliance and automatically bypasses the appliance if either link goes down. These features make the ETAP-5203BP suitable for deployment in critical network paths.

The ETAP-5203BP can also serve as a direct replacement for the DBPS-4005.
