[1] The maximum operating temperature for these load modules lowers the maximum operating temperature to these limits when used in an XM2 or XM12 chassis.

Ixia's Gigabit Ethernet XMVR LAN Services Modules (LSMs) offer Layer 2-3 network testing functionality in a single test system. Each test port supports wire-speed Layer 2-3 traffic generation and analysis and medium performance routing/bridging protocol emulation. With industry-leading16 Dual-PHY ports per module, ultra-high density test environments can be created for auto-negotiable 10/100/1000 Mbps Ethernet over copper as well as Gigabit/100FX Ethernet over fiber. With 12 slots per XM12 High Performance chassis, up to 192 Gigabit Ethernet test ports are supported in a single test system.

Each port on a GE XMVR module contains a RISC processor running Linux and a full testing-optimized TCP/IP stack. This architecture provides the performance and flexibility required for testing routers, switches, broadband and wireless access devices, and many other networking devices.

Ixia's Gigabit Ethernet XMVR LAN Services Module (LSM) is offered in a 16 port configuration, providing scalability and affordability for many testing requirements.
