10/100 Copper Installation and Tech Specs
Installing 10/100
Prerequisite(s):
♦Decide where to place the nTAP and physically mount it, if desired. Depending on the form factor purchased, this may be in a drive bay, rack mount bracket, or wherever it is most convenient.
♦Keep the nTAP horizontal for efficient heat dissipation.
♦The 10/100 nTAP must use straight-through cables. It cannot use crossover cables.
The Copper TAP transmits the analyzer signals through a pair of 10/100/1000 BaseT RJ-45 ports (or 10/100 BaseT if a 10/100 Copper TAP model).
When traffic comes in to Link A, two copies are made in the TAP. One copy is sent out Link B to the switch and the other copy is sent out Analyzer A to the analysis device. A similar thing happens with traffic that comes in Link B. Two copies are made. One copy is sent out Link A and the other copy is sent out Analyzer B. Due to how the TAP is designed, it is not possible for traffic from the Analyzer side to pass to the Link side.

Caution: 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 nTAP. You can provide power to one or both power supply sockets on the back panel of each nTAP. Connecting both sockets to different external power sources provides fail-safe power redundancy for the Analyzer side.
2. Disconnect the cable from your device (typically a switch) and connect it 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 part of a failover or redundancy arrangement, then connect the failover device to Link B.
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 receiving ports of the monitoring device.
Technical specifications for 10/100
This section lists the dimensions, power requirements, supported media, and environmental requirements.
Both power connectors are located on the back panel, along with the model information and serial number.
Power requirements |
AC Input | 100-240V 50/60Hz 0.5A |
Operational Voltage | 5V (+10%/-5%, < 100 mV ripple) |
Operational Current | Typical: <= 1.8 amps; Max: <= 2.8 amps |
Power Dissipation | Typical: 8 watt; Max: 14 watt |
Environmental requirements |
Temperature range | 32°F - 113°F / 0°C - 45°C (operating): The fanless cooling design relies on conduction and convection from the nTAP casing. Your installation environment must provide enough cool airflow for the nTAP casing to maintain an operating temperature less than 113°F/45°C. -52° to +185°F / -47° to +85°C (storage) |
Humidity | 35-85% (non-condensing) |
Supported media |
Link ports | Straight-through RJ-45 cable |
Copper Analyzer ports | Straight-through RJ-45 cable |
Dimensions |
Width | 5.62 in/14.28 cm |
Height | 1.15 in/2.93 cm |
Length | 7.79 in/19.78 cm |
