This section covers the following topics of information.

• DAG 3.6ET Card Architecture

1.3.1 DAG 3.6EP Card Architecture

Description
Ethernet framers
Packet time stamping
The DAG 3.6EP has two independent 10/100 Ethernet interfaces.
Each can be connected to a separate switch or hub, and autonegotiate with the connected equipment.
Each single half or full-duplex 10 or 100Mbps Ethernet connection passes into a port of the DAG card. Two Ethernet framers look at data from each port independently. The DAG card captures from half duplex or full duplex links.
Serial Ethernet data is received by the interface, and fed through a framer into the upper of two Xilinx FPGA’s. This FPGA contains an Ethernet processor and the DUCK timestamp engine.
Because of component close association, packets or cells are time-stamped accurately. Time stamped packet records are then stored in the lower FIFO.

Description
Operating system
Different system
The DAG 3.6ET is designed for tapping both directions of a single copper 10 or 100Mbps Ethernet link in a completely passive and fail-safe manner.
The DAG card will capture from half duplex or full duplex links. The DAG card does not interfere in the link negotiation process in any way, so full duplex links will remain full duplex after being connected through the DAG card.
A single half or full-duplex 10 or 100Mbps Ethernet connection passes into one port of the DAG card, and out the other un-interrupted.
Two Ethernet framers look at data travelling in each direction on the connection without interfering with the link. The DAG card cannot transmit onto this link at all, and even if the DAG 3.6ET is turned off the network link integrity is assured.
Serial Ethernet data is received by the interface, and fed through a framer into the upper of two Xilinx FPGA’s. This FPGA contains an Ethernet processor and the DUCK timestamp engine.
Because of component close association, packets are time-stamped accurately. Time stamped packet records are then stored in a FIFO.
Records transfer from FIFO into lower FPGA, which has interfaces to the PCI bus and then all records are written to host memory.
The DAG 3.6E and associated data capture system minimum operating requirements are:
• PC, at least Pentium II 400 MHz, Intel 440BX, GX or newer chip set
• 256 MB RAM
• At least one free PCI free slot with 3.3V and 5V power
• Software distribution requires free space of 30MB
For convenience, a Debian 3.1 [Sarge] Linux system is included on the Endace Software Install CD. Endace currently supports Windows XP, Windows Server 2000, Windows Server 2003, FreeBSD, RHEL 3.0, and Debian Linux operating systems.
For advice on using a system substantially different from that specified above, contact Endace support at support@endace.com

2.0 INSTALLING DAG 3.6E CARD

EDM01.05-05r1 DAG 3.6E Card User Manual
Introduction
A DAG 3.6E card can be installed in any free Bus Mastering PCI slot.
Although the driver supports up to four DAG cards by default in one system, due to band width limitations there should not be more than two cards on a single PCI-bus.
In this chapter
This chapter covers the following sections of information.
• Insert DAG 3.6E Card into PC
• Connecting DAG Card Ports

2.1 Insert DAG 3.6E Card into PC

Description
Procedure
Step 1.
Step 2. Fit Card
Inserting the DAG 3.6E card into a PC involves accessing the bus slot, fitting the card, and replacing bus slot cover.
Follow these steps to insert the DAG 3.6E card.
Access bus Slot
Power computer down.
Remove PCI-bus slot cover.
Insert into PCI-bus slot.
Step 3. Replace bus Slot Screw

2.2 Connecting DAG Card Ports

EDM01.05-05r1 DAG 3.6E Card User Manual
Description
The DAG 3.6EP and DAG ET card ports are for ethernet connection, and one port for time synchronisation.
In this section
This section covers the following topics of information.
• Connect DAG 3.6EP Card Ports
• Connect DAG 3.6ET Card Ports
• Timing Synchronization

2.2.1 Connect DAG 3.6EP Card Ports

Description
Figure
With the DAG 3.6EP there are two RJ45 ethernet ports that can be connected independently to any two Ethernet devices.
Typically the DAG card is connected to two hub, switch, or router ports.
Figure 2-1 shows the typical DAG card connection to two hub, switch, or router ports.
Pin jumpers
There are a number of pin jumpers on the DAG 3.6EP card. These are set when a card is manufactured, and must never be altered.
Voiding warranty
Changing jumper settings can cause the card to permanently malfunction and may void the product warranty

Figure 2-2. Typical DAG Card Connection Between a NIC and Switch.
Sometimes the DAG card may be inserted between two switches or routers. In such cases, a cross-over Ethernet cable is required. The Router directly connected can be referred to as the ‘Switch’ end of the connection, and the Router connected via the cross-over cable can be referred to as the ‘NIC’ end of the connection.
Figure 2-3 shows a typical DAG card insertion between two switches or routers.
