Chapter 16: IXIA Xcellon-Lava Load Modules

This chapter provides specification and feature details of the Xcellon-Lava 40/100 Gigabit Ethernet load modules. This family of load modules consist of the following 3-port cards:

The Xcellon-Lava 40/100-Gigabit Ethernet load modules belong to the family of Ixia's High Speed Ethernet (HSE) products. These load modules combine the advantages of the Xcellon architecture and provide the highest 40GE and 100GE port densities. Lava load modules can be used for testing layer 1 to layer 7 applications. They are supported by Ixia's test applications, including IxNetwork and IxLoad.

Xcellon-Lava load modules are used for testing high-density data center 40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) network equipments. 40GbE and 100GbE are high-speed computer network standards developed by the IEEE 802.3ba. Lava load modules extends the 802.3 protocol to operating speeds of 40 Gbps and 100 Gbps in order to provide greater bandwidth while maintaining maximum compatibility with the installed base of 802.3 interfaces.

Xcellon-Lava load modules are compatible with Ixia's XG12™, XM12, and XM2 chassis, and a broad range of Ethernet interfaces, allowing real-world, layer 1 to layer 7 test and measurement in a single chassis.

LavaAP40/100GE 2P-NG load module has capabilities similar to LavaAP40/100GE 2P and includes N2X support.

LED function table

The LED functions are described in the following tables.

Table 16-1. Xcellon-Lava LED Ports
LED Label	Usage
Link	Green if Ethernet link is up (established) or the port is in a forced Link Up state, OFF (no color) if link is down. Link may be down due to no signal or no PCS lock.
Tx Active	Green indicates that Tx is active and frames being sent; red indicates Tx is paused; off indicates Tx is not active.
Rx Active	Green indicates that Rx is active and frames being received; red indicates Rx is paused; off indicates Rx is not active.
Rx/Error	Green indicates valid Rx frames are being received; red indicates error frames being received; off indicates no frames being received.
Pwr Good	Green when power is on, red if power fault occurs.
