establish link with the Network A and B ports of the powered tap. Check for green link lights on the
Network A and B ports. These lights should flash to indicate activity if data is passing on the link.
2.3 Once valid link has been established the proper functionality of the power fault tolerance feature must
be tested. Disconnect the power supplies from Unit A and check for link light on the endpoint devices
of the link to confirm that they have re-established link with one another through the passive tap.
2.4 When Unit A is powered up or down a momentary interruption of link always occurs as the relay
based power fault tolerance system moves to a closed position to provide a passive non-powered
bypass or moves back out of position to once again allow data to pass through the powered tapping
circuit. This interruption may be reduced to the shortest possible duration by setting the endpoint
devices to Port Fast, Fast Learn or an equivalent setting.

CONNECTING MONITORING TOOLS
3.1 Before connecting the tools first verify that the fiber jumper cables between Unit A and Unit B are
properly connected and showing link when power has been applied. Green link lights should appear
adjacent to the A Out and B Out ports of Unit A as well as the A In and B In ports of Unit B.
3.2 Using a Cat 5 or higher cable of appropriate length connect the 1-A Monitor port to the appropriate
monitor / capture card of a monitoring tool or data collection device. Using a second cable connect
the 1-B Monitor port to an additional monitor / capture card on the same tool or device.
3.3 Verify link by checking for a green light adjacent to each tap Monitor port and also on the tool or
device to which it is connected. If data is passing on the tapped link these light should blink to
indicate the presence of activity
3.4 Additional validation of proper installation should be provided by checking the attached monitoring
tool or device for the presence of data packets from both the Rx and Tx sides of the tapped link.
3.5 Additional monitoring tools or devices should be connected to the remaining Monitor ports using the
same procedures.
Congratulations - the installation is now complete!
TROUBLESHOOTING
SYMPTOM
Link stops passing data when
power to A unit is lost
No link on endpoints of
tapped link
Tools on A unit see data but
tools on B do not see data
Link is functioning properly
but no data is visible to any of
the tools on A unit or B unit
Tools on B unit see only one
side of conversation
POSSIBLE CAUSES AND SOLUTIONS
Passive bypass is directional – try reversing position of cables in
Network A and Network B.
Tap assembly is for 1000 Mbps links only – verify that endpoint
devices are both 10/100/1000 capable and set to Auto or fixed.
Confirm that B unit has power and confirm that A Out and B Out
fiber ports of A unit are properly connected to the A In and B In
ports of B unit – also check that green link lights are illuminated
and flashing to indicate passing of data.
Check to ensure that at least one functioning power supply is
connected to each of the two units and that the appropriate
green power indicators on front panel are illuminated.
Verify that the A Out and B Out fiber ports of A unit are properly
connected to the A In and B In ports of B unit and confirm that
green link lights are illuminated.
