Ethernet Interface

The XPress DR+ includes a two-port unmanaged Ethernet switch with a future option to migrate to a managed solution.

The internal IEEE 802.3-compliant Ethernet switch is non-blocking, using a 1K MAC address lookup table with store-and-forward architecture. The XPress DR+ supports auto-negotiation for 10Base-T or 100Base-TX in full and half-duplex modes, as well as automatic MDI/MDIX crossover, allowing use of both straight-through and crossed Ethernet cables. The unit also supports IEEE 802.1d spanning tree, which protects against the possibility of a network loop.
