Introduction
Get total trafc visibility for 10/100/1000 monitoring and security devices
by placing Net Optics Gig Zero Delay Taps and 10/100/1000 BaseT Taps on
critical network links. These Taps support passive monitoring of 10/100/1000
links at 10, 100, or 1000 Mbps. “Passive” means that network trafc continues
to ow even when the Tap does not have any power. These devices are ideal
when a passive Tap is required for use with a variety of copper monitoring
devices. (The link speed and the monitoring device speed must be the same;
the Tap does not perform data rate conversion.)
Gig Zero Delay Tap & 10/100/1000BaseT Tap
For superior reliability, these Taps feature Link Fault Detect
TM
(LFD), which
gives the devices connected to the Tap critical information about link status. If
either side of the bi-directional link fails, the Tap immediately communicates the
fault to both devices, reducing the time required to activate a redundant path.
Transparent Access
The Gig Zero Delay Taps and 10/100/1000 BaseT Taps establish permanent
passive access ports without introducing a point of failure or disturbing
other network connections. The Gig Zero Delay Tap either auto-negotiates
communication or uses an external DIP switch to set xed speed and duplexing
parameters. These passive Taps deliver full-duplex monitoring with zero impact
on network trafc around the clock.
True Zero Delay
The breakthrough design of the Net Optics Gig Zero Delay Taps (but not the
10/100/1000 BaseT Taps) ensures zero impact on network trafc when the Tap
experiences a power on or power off event. These devices are the world’s rst
and only 10/100/1000 taps offering true “zero delay” technology.
Highly sensitive network locations can improve monitoring performance with
the innovative features of Net Optics Gig Zero Delay Taps. If power is lost to
other 10/100/1000 taps, the connected devices may introduce delays as they
detect the power loss and try to re-establish their link.
Net Optics’ pioneering design ensures that any loss of power to the Tap is
transparent to the network, and does not affect the ow of trafc through the Tap
– completely eliminating packet delay and loss as potential security issues.

Simply Plug It In
Full-duplex monitoring is a snap when each side of the signal is sent to
a separate NIC on the monitoring device. All network and monitoring
cables necessary for plug-and-play deployment are included with the Tap.
Security and Visibility
Without an IP address, monitoring devices are isolated from the
network, dramatically reducing their exposure to attacks. However, the
monitoring device connected to the Tap still sees all full-duplex trafc
as if it were in-line, including Layer 1 and Layer 2 errors.
Reliability
For extra uptime protection, Net Optics Gig Zero Delay Taps and
10/100/1000 BaseT Taps offer redundant power connections. Should
the primary power source fail, the Tap automatically switches to the
backup power source. Power LEDs on the front of the Tap indicate the
current power source.

Link Fault Detect
TM
The Gig Zero Delay Taps and 10/100/1000BaseT Taps have Link Fault Detect
on the Network ports. The Tap negotiates separately with each side of the fullduplex link, detecting if either side fails. In the event of a failure, the Tap ceases
negotiation with the remaining side, enabling a clean fail-over to a redundant
network connection (if one is available). Link Fault Detect requires that both
sides of the full-duplex link and communicating at the same speed.
Cabling Guidelines
If both of the devices connected to the Tap network ports are 10/100BaseT
devices that do not support Automatic MDI/MDI-X Conguration (see
explanation, following), then specic cabling must be used in order to
maintain a successful link when power is removed from the Tap. In this case:
• If the link is currently made with a straight-through cable, connect TP-CU3
to the network with two straight-through cables.
• If the link is currently made with a cross-over cable, connect TP-CU3 to the
network with one cross-over cable and one straight-through cable.
In other words, Gig Zero Delay Taps and 10/100/1000BaseT Taps act as
straight-through connections. (The Net Optics 10/100BaseT Taps are different;
they act as crossover connections.)
Automatic MDI/MDI-X Conguration
The need for crossover cabling is eliminated by a feature in the 1000Base-T
standard called Automatic MDI/MDI-X Conguration (IEEE 802.3-2005,
40.4.4). Ports with this feature detect the positions of the transmit and receive
7
Page 11
Gig Zero Delay Tap & 10/100/1000BaseT Tap
pins, and automatically connect them correctly. All 1000BaseT ports support
this feature, as do many 10/100BaseT ports on newer equipment.
The Gig Zero Delay Taps and 10/100/1000BaseT Taps support Automatic
MDI/MDI-X Conguration on all of its ports. However, when the Tap does
not have power, it passively connects the two network ports so the link
remains active. This passive connection is made straight-through. Therefore,
if both of the devices connected to the Tap network ports are 10/100BaseT
devices that do not support Automatic MDI/MDI-X Conguration, then the
positions of the transmit and receive pins cannot be detected automatically,
and straight through or crossover cables are required (as specied in the previous list) in order to maintain a successful link.
Connecting to the Network
To connect the Tap to the Network link:
1. Connect Network Port A to the appropriate switch, server or router using a
CAT5e cable.
2. Connect Network Port B to the appropriate switch, server or router using a
CAT5e cable.
3. Verify that the Tap Network Ports are cabled in-line between two devices.

Note:
If you are using a xed-speed setting, all
devices connected to the Tap should also be set
to that same speed. Furthermore, you should
set only one speed switch to ON. If more than
one speed switch is set to ON, the Tap uses the
fastest speed.
Note (TP-CU3 & TP-CU3-DC only):
Following any modications to the DIP switch
