1.2 DAG 6.1S Card Product Description
Description
Figure
The DAG 6.1S card is of a series specifically designed for network
surveillance applications. It is optimized to enable header-only or full
packet capture from PoS OC-192c or STM-64c links, and 10 Gigabit
Ethernet 10GBase-LR and 10GBase-LW links.
Figure 1-1 shows the DAG 6.1S PCI-X card.
Figure 1-1. DAG 6.1S PCI-X Card.
Installed in a PCI-X 1.0 slot the DAG 6.1S card only operates at 66, 100,
and 133 MHz PCI-X for full packet capture at line rate and allows
recording of all header information and/or payload with a high precision
timestamp.
The packet header and payload information can be stored for later in-depth
analysis, or used in real-time for a variety of network monitoring
applications, such as billing and intrusion detection systems.
IP header traces can also be used operationally to determine link
performance and application mixes, find “top talkers” or generate
source/destination AS matrices for specific network links.

1.3 DAG 6.1S Card Architecture
Description
Figure
Serial optical data is received by the optical interface, and fed into a
physical layer ASIC. The packet data is then fed immediately into the Rx
FPGA. This FPGA contains the DUCK timestamp engine, and packet
record processor.
Because of component close association, packets or cells are time-stamped
accurately. Time stamped packet records are then stored in an external
FIFO and passed into the PCI-X FPGA for transmission to the host.
Figure 1-2 shows the DAG 6.1S card major components and data flow.

1.4 DAG 6.1S Card Extended Functions
Description
The shipped version of the DAG 6.1S does not contain a transmit path, it
is intended to be used with fibre optic splitters.
Contact the Endace customer support team at support@endace.com to
enable effective use of extended functions.
1.5 DAG 6.1S Card System Requirements
Description
The DAG 6.1S card and associated data capture system minimum
operating requirements are:
• PC, at least Intel Xeon 1.8GHz or faster
• Intel E7500, ServerWorks Grand Champion LE/HE or newer chip
set
• 256 MB RAM
• At least one free PCI-X 1.0 slot supporting 66MHz operation
• Software distribution free space of 30MB

2.0 INSTALLING DAG 6.1S CARD
Introduction
Given the DAG 6.1S card can be installed in any free PCI-X 1.0 slot, it
operates at 66, 100, and 133 MHz. The DAG 6.1S will not operate in 32
or 64-bit PCI slots.
Higher speed slots are recommended for best performance.
The DAG 6.1S should be the only device on the PCI-X bus if possible, as
the cards make very heavy use of PCI-X bus data transfer resources.
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 one
card on a single PCI-X bus.
In this chapter
This chapter covers the following sections of information.
• Installation of Operating System and Endace Software
• Insert DAG 6.1S Card into PC
• Installation of Operating System and Endace Software
2.1 Installation of Operating System and Endace Software
Description
If the DAG device driver is not installed, before proceeding with the next
chapter, install the software by following the instructions in EDM04-01
Endace Software Installation Manual.
Go to the next chapter of information when the DAG device driver is
installed.
2.2 Insert DAG 6.1S Card into PC
Description
Procedure
Step 1. Access bus Slot
Inserting the DAG 6.1S card into a PC involves accessing the bus slot,
fitting the card, and replacing the bus slot screw.
Follow these steps to insert the DAG 6.1S card.
Power computer down.
Remove PCI-X bus slot cover.

Step 2. Fit Card
Insert into PCI-X bus slot.
Ensure free end fits securely into a card-end bracket that supports the card
weight.
Step 3. Replace bus Slot Screw
Secure card with screw.
Step 4. Power up computer
2.3 Connect Card Ports
Description
There is one square plastic SC-type optical connector on the 6.1S DAG
card for the received optical signal. There is no TX port on the card.
The card has an 8-pin RJ45 socket for time synchronization input. This
socket must never be connected to an Ethernet network or telephone line.

3.0 SETTING DAG 6.1S CARD OPTICAL POWER
Description
Optical power

Configuration
In this chapter
The optical power range depends on the particular device fitted on the
DAG 6.1S card.
The DAG 6.1S card is shipped fitted with the GTRAN GT10-RXU
1310nm single mode receive module by default.
Optical power is measured in dBm – decibels relative to 1 mW where 10
dB is equivalent to a factor of 10 in power.
The numbers are all negative, showing powers below 1 mW. The most
sensitive devices can work down to about –30 dBm, or 1 uW.
The following table describes the DAG 6.1S card optics power module
configuration.

3.1 DAG 6.1S Card Optical Power Input
Description
The optical power input into the DAG 6.1S card must be within a
receiver’s dynamic range.
When optical power is slightly out of range an increased bit error rate is
experienced. If power is well out of range the system cannot lock onto the
SONET frames. In extreme cases of being out range excess power will
damage a receiver.
When power is above the upper limit the optical receiver saturates and
fails to function. When power is below the lower limit the bit error rate
increases until the device is unable to obtain lock and fails.

3.1 DAG 6.1S Card Optical Power Input
, continued
Input power
The DAG 6.1S card is set up to measure the optical power at the receiver,
and to make sure that it is well within the specified power range of -9
dBm.
Input power is adjusted by:
• Changing splitter ratio if power is too high or too low, or
• Inserting an optical attenuator if power is too high.
3.2 Splitter Losses
Description
Single mode
fibre loss
Multi-mode
fibre loss
Splitters have the insertion losses marked on packaging or in
accompanying documentation.
• A 50:50 splitter will have an insertion loss of between 3 dB and 4
dB on each output
• 90:10 splitter will have losses of about 10 dB in the high loss output,
and <2 dB in the low loss output
The GT10-RXU uses 1310nm optics. Splitters used must be designed for
1310nm as the insertion loss will vary for different wavelengths.
A single mode fibre connected to a multi-mode input has minimal extra
loss.
A multi-mode fibre connected to a single mode input creates large and
unpredictable loss.

4.0 CONFIDENCE TESTING DAG 6.1S CARD
Introduction
The confidence testing is a process to determine the DAG 6.1S card is
functioning correctly.
The process also involves a card capture session, and demonstrates
configuration in the style of 'What You See You Can Change', WYSYCC.
Interface statistics are also inspected during this process. There is also
information in this section regarding reporting of problems.
