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.

Port LEDs
Each LM100TXS8 port incorporates a set of 2 LEDs, as described in the following table.
LED | Color | Usage |
---|---|---|
Tx/L |
Orange |
10Mbps link. Pulses on activity. |
Green |
100Mbps link. Pulses on activity. |
|
RX/E |
Orange |
Pulses on error. |
Green |
Full duplex. Pulse on activity. |
All other 10/100 card types incorporate a set of 6 LEDs, as described in the following table.
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.
Pin | Signal |

Port 1: High pulse for each packet matching User Defined Statistic 1 |
2 |
Port 2: High pulse for each packet matching User Defined Statistic 1 |
3 |
Port 3: High pulse for each packet matching User Defined Statistic 1 |
4 |
Port 4: High pulse for each packet matching User Defined Statistic 1 |
