Connecting to the Monitoring Devices
1. If you have a fiber model, install the appropriate SFP or SFP+ transceiver
modules in the Monitor ports. (You need to install modules only in ports to
which you will be connecting monitoring tools). Push each module in until
you hear a click and see the SFP Present LED above the port illuminate.
2. Connect any Monitor A port to the appropriate monitoring device using an
appropriate cable. The device will monitor Network traffic being received
at Network A port over this cable.
3. Connect any Monitor B port to another NIC on the same monitoring device
using an appropriate cable. The device will monitor Network traffic being
received at Network B port over this cable.
4. Connect other monitor devices to the remaining monitor ports as desired.
All of the Monitor A ports mirror the traffic being received at Network
A, and all of the Monitor B ports mirror the traffic being received at
Network B.

Note: _______________________________________________________________
On inline models, if traffic is passing between the devices on both sides of
the Network ports but no traffic can be seen on the monitoring ports, the
cables plugged into the Network ports may have TX and RX reversed. To fix
this condition, reverse the TX and RX connections on BOTH Network A and
Network B ports. If you reverse the connections on only one of the ports,
traffic will not be able to pass between the devices.
