How to install the SFPs
This product uses hot-swappable SFPs, but you should disconnect any cables before changing the SFP modules.
Caution: Wear a grounding strap when handling SFPs to avoid damaging them or other components. Avoid exposure to laser radiation from optical components by keeping the dust plugs installed until you are ready to install the cables.
There are numbers etched into the back plate of each Gen3 capture card along the top. These etched numbers represent the port number assignments from top to bottom. For example, port 1 is at the top and port 4 at the bottom. This helps you determine the port number that any SFP, SFP+, QSFP+, or QSFP28 is plugged into. If you need to connect the probe to a monitoring interface (TAP or SPAN/mirror) different from that shipped with the unit, simply obtain the necessary SFP for your application and insert the desired interface.
The Gen3 capture card has two ports for 40 Gb transceivers (QSFP+).
Transceivers can be inserted into any open port and in any order.
The transceivers connection is hot-swapped at any time, but it is recommended you then re-launch Observer so that the new speeds can be identified.
