Excels at High-Bandwidth Communications

The XChange3021 supports x4 width Gen3 (backwards compatible with Gen1 and Gen2) PCI Express links between up to 6 slots in an OpenVPX™ backplane to facilitate high-bandwidth, memory mapped communications between the payload boards. In addition, a x8 PCIe link is provided to an onboard XMC mezzanine site to allow for onboard I/O and protocol expansion.

The XChange3021's Ethernet switch supports various configurations of up to ten 10 Gigabit or Gigabit Ethernet ports. The Ethernet switch supports jumbo packets up to 12 kB, IPv6, Energy Efficient Ethernet (EEE), and a comprehensive set of IETF RFCs and IEEE protocols.

Supports Embedded Services Router (ESR) with Cisco IOS®

When paired with the optional XPedite5205 XMC/PMC embedded router module, the XChange3021 includes Cisco IOS® IP routing and Cisco Mobile Ready Net capabilities. With this technology, the router provides highly secure data, voice, and video communications to stationary and mobile network nodes across both wired and wireless links.
