Caution: Before you temporarily break the link between the device of
interest and the network, you may want to shut down access to that device
and notify users of the down time.
1. Ensure that power is connected to the nTAP. You can provide power to one
or both power supply sockets on the back panel of each nTAP. Connecting
both sockets to different external power sources provides fail-safe power
redundancy for the Analyzer side.
The network pass-through (Link side) remains unaffected even if power
to the nTAP is interrupted. If you do lose power, you will temporarily lose
connectivity while the devices renegotiate their connection. The analyzer side
will be down until power is reestablished, and during this time some packets
may be dropped.
2. Disconnect the cable from your device (typically a switch) and connect it to
Link B. You want to connect Link B first because it negotiates its network
speed first, and Link A then must use the same speed as Link B. If your link
is part of a failover or redundancy arrangement, then connect the failover
device to Link B.
3. Connect your network device (or primary device in a failover arrangement) to
Link A.
4. Connect the Analyzer ports on the TAP to the receiving ports of the
monitoring device.
