IXIA 10/100 Load Modules

This chapter provides details about 10/100 family of load modules specifications and features.

The 10/100 family of load modules implements Ethernet interfaces that may run at 10Mbps or 100Mbps. Different numbers of ports and interfaces are available for the different board types. The features available for these load modules are included in the Port Features by Port Type matrix, which is located on the ixiacom.com website under Support/User Guides/Spreadsheets.

One of the family's modules (the LM100TXS8) is shown in the following figure.

LED Color Usage

Tx/L

Orange

10Mbps link. Pulses on activity.

Green

100Mbps link. Pulses on activity.

RX/E

Orange

Pulses on error.

Green

LED Label Usage

Link

Green if link established. For Mii and RMii boards, Red if no transceiver is detected.

100

Green for 100Mbps.

Half

Green for half duplex operation.

Tx/Coll

Green during data transmission. Red during collisions.

Rx/Err

Green during error free reception. Red if errors received.

Trig

Follows the state of the Trigger Out pin, which is programmed through User Defined Statistic 1.

Trigger Out Values

The signals available on the trigger out pins for all cards in this category are described in the following table. The LM100TXS8 and LM100TX8 cards output 60ns pulses and all other cards output 40ns pulses.
