Installing the Copper Aggregator TAP

Chapter 4 Aggregator TAPs

rev. 1

 Connect the TAP to your analyzer or other monitoring device

using standard Ethernet cables.

Figure 10 Connecting the TAP to the network device, switch, and analyzer

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).
