Overview

The P/XMC-651 (XMC/PMC-651) is a 12-port Gigabit Ethernet switch packaged in the industry-standard XMC and PMC form factors. It is designed to support “in-chassis” networks with managed Layer-2 switching capabilities. Part of a family of Gigabit Ethernet switching/routing products from Curtiss-Wright, the P/XMC-651 – XMC Gigabit Ethernet Switch is an ideal low-cost zero-slot Ethernet switching solution that can be added to any base card with an XMC mezzanine slot. These switches are designed for rugged applications with backplane I/O and are offered in a full range of ruggedized air-cooled and conduction-cooled versions.

Both the XMC-651 and PMC-651 implement Ethernet switching functions via Broadcom® 10th generation switching technology. A single integrated switching fabric provides non-blocking wire-speed Ethernet switching for up to 12 Gigabit Ethernet ports. Both the XMC-651 and PMC-651 offer 8 ports of Gigabit Ethernet supporting tri-speed 10/100/1000Base-T with auto-negotiation and auto-MDI/MDIX crossover support. For some XMC variants, an additional four ports are offered, supporting SerDes (1000Base-X) GbE, providing flexibility when connecting in-chassis devices.

The 12-port Gigabit Ethernet switch, P/XMC-651 family supports Layer-2 multicast, where a single source device can send data to multiple destination devices. This technique is extremely powerful when distributing data such as video and telemetry information. The P/XMC-651 Ethernet Switch family offers full support for jumbo frames up to 9K bytes. The 651 family connects only to the XMC and PMC connectors to obtain power and for Ethernet I/O connections. No software driver is needed.
