
Connect the TAP to your analyzer or other monitoring device
using standard Ethernet cables.

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
and Link A then must use the same speed as Link B. If your link is
under test as part of a failover or redundancy arrangement, then
connect the failover device to Link B. See
“How do I connect my
failover devices?” on page 55.
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 analyzer(s).
