IXIA 10/100/1000 Load Modules
This chapter provides details about Ixia 10/100/1000 family of load modules the specifications and features.
The 10/100/1000 family of load modules implements Ethernet interfaces that run at 10 Mbps, 100 Mbps, or Gigabit (1000 Mbps) speeds. Different numbers of ports and interfaces are available for the different board types. The specifications for these load modules are listed in the table. A representative selection of these load modules are pictured on the pages that follow.
The application load module ALM1000T8 is an 8-port 10/100/1000 Mbps Base T Ethernet copper module which supports the Real World Traffic Suite (includes IxVPN, IxChariot, and IxLoad). This module also supports ARP, PING, and independent Linux SDK applications. The ALM1000T8 load module is shown in the following figure.

ALM1000T8
The ALM100T8 has a feature that is non-conformant with the IEEE 802.3 specification. According to the specification, all 4 pairs of signals must be connected in gigabit copper mode for auto-negotiation to function. On the ALM100T8, if auto-negotiation fails using all 4 pairs, auto-negotiation is attempted using only the two pairs used in 10/100 modes. This allows auto-negotiation to succeed even if gigabit mode is enabled for auto-negotiation and a 10/100 only cable is used.
Card LEDs
Each ELM1000ST2, LM1000STX2/4 and LM1000STXS2/4 card incorporates a single LED, as described in the following table.
LED Label | Usage |
---|---|
Trig |
The value of the `OR' function of all of the trigger out ports on the board. The LED's color is orange. |
The ALM1000T8 has a card-level `mgmt' LED next to Port 8. This LED is not currently used.
Port LEDs
Each port on the ALM1000T8 module incorporates a set of 2 LEDs, as described in the following table. The ALM1000T8 also has a card-level `mgmt' LED next to Port 8; this LED is not currently used.
LED Label | Usage |

LED Label | Copper | Fiber |
---|---|---|
Link/Tx (Upper LED) |
Color is used to indicate the link speed:
Flashing indicates transmit activity. Off if link is down. |
Green indicates link has been established and flashes during transmit activity. |
Rx/Error (Lower LED) |
Three conditions apply:
|
Green indicates link has been established and flashes during receive activity. Continuous red indicates a receive error. |
Each ELM1000ST2, LM1000STX2, LM1000STX4, LM1000STXS2, and LM1000STXS4-256 port incorporates a set of 6 LEDs, as described in the following table. The LEDs are arranged next to the two connectors associated with each port: Speed, Slave, and RJ45 Link/Tx/Coll are next to the RJ45 connector and Rx/Err, Half, and SFP Link/Tx/Coll are next to the SFP connector.
