abrasive surfaces, door and window jambs, routing near high EMI / EMF (Electro-Magnetic Induction / Field)
transformers or equipment, and corrosive fluids or gases.
2. Install the Network Instruments GPS Synchronization System in your rack with the provided screws.
3. Attach a grounding wire to the ground post on the rear of the device.
4. Connect the power supply and the secondary power supply, if you are using it, to the outlet. The unit has
power when the power supply is connected. There is no power switch.
5. Connect the antenna to the GPS IN port on the rear of the device.
6. Using Ethernet cables connect the GPS System to your GigaStor probe's Gen2 capture card.
7. On the GigaStor probe, choose Start > Control Panel > Device Manager > Network Instruments Capture
Adapters > Network Instruments 10 Gigabit Capture Adapter. Right-click and choose Properties.
8. Click the Advanced Settings tab. Select your GPS Cable Length. This is the cable length from the GPS
Synchronization System to your GigaStor probe. It is not the cable length for the GPS antenna. Click OK. Your
GigaStor probe will now use GPS accurate timing for its captures.
The Gen2 capture card synchronizes with the GPS System every second. Should the GPS System lose power:
if you have a secondary power supply or UPS, it will failover and continue functioning.
if you do not have a secondary power supply or it fails, the Gen2 capture card locks in the last known
clock drift and uses it until a connection to the GPS System is reestablished.

Configuring the 10 Gb Gen2 card with a SPAN port

When monitoring 10 Gb traffic, you may need to make configuration changes to the 10 Gb adapter depending
upon whether you use a TAP or SPAN port. With a TAP, no configuration changes are required. With SPAN ports,
you must enable auto-negotiation to allow the SPAN port to activate the link.
If auto-negotiation settings are left unchecked, the link will not connect. To activate auto-negotiation:
1. On the GigaStor system, choose Start > All Programs > Accessories > Windows Explorer. Choose My
Computer and right-click and choose Manage. The Computer Management window opens.
2. In the tree on the left, select Device Manager.
3. In the tree on the right, expand Network Instruments Capture Adapters.
4. Choose Network Instruments Gen2 10 Gigabit Capture Adapter, right-click and choose Properties. Click the
Advanced Properties tab.
5. Select Auto-Neg Enable and Tx Enable for both ports. This allows activation of the link having the SPAN port.
If these are not checked, the link will not become active.
