  • Include a TAP port for monitoring full-duplex inline traffic
  • Compatible with PoE. PoE pass-through between two inline ports
  • Support Link Fault Pass-Through

    Dualcomm DBPS-4005 is a low-cost Ethernet Bypass switch for use with a 10/100/1000Base-T Ethernet link. DBPS-4005 typically deployed together with a network security appliance such as an intrusion detection system (IDS) or an Intrusion prevention system (IPS).

    The two network ports of DBPS-4005 will fail over automatically to maintain link connectivity when DBPS-4005 loses power. DBPS-4005 also detects the link status between the attached appliance, and it will automatically bypass the attached appliance if the link status is detected as invalid.  As such, DBPS-4005 can be used as an Ethernet Bypass Switch for deployment in a critical link path.

    DBPS-4005 provides a built-in monitor port for capturing full-duplex inline traffic. As such, it can also be used as a network TAP.

    When a link goes down on either network port of DBPS-4005, the link on the other network port of DBPS-4005 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.

    DBPS-4005 is compatible with Power-over-Ethernet (PoE), which is capable of passing PoE inline power between two copper inline ports. 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.

    DBPS-4005 can be rack-mounted with the optional mounting hardware kit (Model No. RMKIT-1000), which is available for purchase separately.
