Introduction
Get total trafc visibility for 10/100/1000 monitoring and security devices
by placing Net Optics 10/100/1000BaseT Taps on critical network links.
10/100/1000BaseT Taps support passive monitoring of 10/100/1000 links at
10, 100, or 1000 Mbps. This Tap is ideal when a passive Tap is required for
use with a variety of copper monitoring devices.
For superior reliability, the 10/100/1000BaseT Tap features Link Fault De-
tectTM (LFD), which gives the devices connected to the Tap critical informa-
tion about link status. If either side of the bi-directional link fails, the Tap im-
mediately communicates the fault to both devices, reducing the time required
to activate a redundant path.
Transparent Access
The 10/100/1000BaseT Taps establish permanent passive access ports without
introducing a point of failure or disturbing other network connections. The
10/100/1000BaseT Tap either auto-negotiates communication or uses an
external DIP switch to set xed speed and duplexing parameters. These pas-
sive Taps deliver full-duplex monitoring with zero impact on network trafc
around the clock.
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 trafc as if it were in-line,
including Layer 1 and Layer 2 errors.
Reliability
For extra uptime protection, Net Optics 10/100/1000BaseT Taps offer re-
dundant 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.

LED Indicators
Power Indicator: Current power source LED illuminates white.
Link/Activity Indicator: Located in the upper right hand corner. If a good
link is established, the LED illuminates a steady green. If there is current
activity on this link, the LED ashes.
10/100/1000 Indicator: Located in the upper left hand corner. If the Port
is set to 10 Mbps, the LED will illuminate orange. If the Port is set to 100
Mbps, the LED will illuminate yellow. If the Port is set to 1000 Mbps, the
LED will illuminate green.
Link Fault DetectTM
The 10/100/1000BaseT Tap has Link Fault Detect on the Network ports. The
Tap negotiates separately with each side of the full-duplex 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 connec-
tion (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 connecting to Switches or Hubs, use CAT5e RJ45 cross-over cabling.
If connecting to Routers or NICs, use CAT5e RJ45 straight-through
cabling.
MDI Cross-over
Cross-over cables are required for 10/100BaseT devices that do not support
MDI cross-over function. When the 10/100/1000 Tap is not receiving power,
links are negotiated between the devices connected to the Tap’s network ports
A and B. If these devices do not support MDI cross-over function, a cross-
over cable is required to establish the link. Gigabit mode works with both
cross-over or straight-through cables.

DIP Switch Settings
You set the communication parameters from the 8-position DIP switch located
on the rear panel of the 10/100/1000BaseT Tap. Parameters set with the DIP
switch apply to all ports. If you plan to used xed settings, connected devices
must match the settings you select for the Tap.
Note: _______________________________________________________________
If you are using xed-speed settings, 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.
Following any modications to the DIP switch
settings, it is necessary to power cycle the TAP
for the changes to take affect.
