TAP
When traffic comes in to Link A, two copies are made in the
TAP. One copy is sent out Link B to the switch and the other
copy is sent out Analyzer A to the analysis device. A similar
thing happens with traffic that comes in Link B. Two copies
are made. One copy is sent out Link A and the other copy is
sent out Analyzer B.

AUTION
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 TAP. You can supply power
to one or both power supply sockets on the back panel of each
TAP. 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 TAP 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.
2
Connect your device (typically a switch) to Link B. You want to
connect Link B first because it negotiates its network speed first
