NEOX NETWORKS NEOXPacketRaven Hybrid Singlemode Multimode 1G Fiber TAPs User Guide
1. More Highlights
– Plug-n-Play, no complex configuration necessary
– Secure, rock-solid FPGA-based design
– Support for up to 16k jumbo frames
– Mirrors 100% of traffic including FCS/CRC errored packets that may be
dropped by SPANs discarded
– Can be powered by redundant AC/DC power supplies (5V)
– Designed, assembled, certified and tested in Germany
2. Front View – Connections and LEDs
(A) LC Network ports A & B
(B) RJ45/SFP Monitoring ports A & B and Status LEDs (see section 2.1)
(C) 12-48V DC power LED (see section 3.)
If power is supplied via the 12-48V DC connection, this LED lights up.
(D) 2 power LEDs for AC/DC 5V (see section 3.)
It is possible to connect up to 2 power supply units to ensure power supply
redundancy.
(E) Aggregation-Modus LED (see section 6.1)
If the Aggregation mode is activated instead of the standard Breakout mode,
this LED lights up.
2.1 Front View – Meaning of the Port LEDs
The
right-hand port LED lights up if there is a functioning 1G connection. If
network data is also being transmitted, the right-hand port LED starts
flashing.
3. Back View
(A) DIP switch for setting the TAP mode (see section 6.)
(B) Connection for 12-48V DC voltage.
The polarity at the DC connection is irrelevant, since the TAP automatically
detects the live wire and supplies the power supply to the TAP in the required
form!
(C) Redundant connections for AC/DC power supplies (5V) For reasons of
compatibility and EMC protection, our TAPS may only be operated with the
supplied power supplies certified together with the TAP. If the TAP is
nevertheless operated with power supplies other than those supplied, any
warranty claim granted for the TAP will be voided!
4. Front panel – mobile or mounting kit / mounting frame version
Our TAPs are available with a front panel for mobile use – as well as with
mounting frames (-ERW versions) for permanent installation in our PRP-1U3
server cabinet mounting frame, which provides space for three of our portable
TAPs each.
Server rack mounting frame PRP-1U3 for portable TAPs
Of course, TAPs with mounting frames can also be used in mobile applications!
5. Advanced functions of Hardened TAPs
6. Connection reliability in case of power loss
With all our active Hybrid Network TAPs it is guaranteed that a loss of the
TAP power supply will not lead to a failure of the active network line.
Only the devices connected to the monitoring port may no longer be supplied
with data.
7. Split Ratios / Light Extraction
In order to tap data from an optical network connection, it is necessary to
decouple or split a part of the available light signal.
The split ratio is the ratio of the amount of light that is still available
for the fiber optic network connection in relation to the amount of light that
is diverted or split off to the monitoring ports of the (passive) fiber optic
Network TAPs.
A split ratio of e.g. 70/30 means that 70% of the light is still available for
the network connection and 30% is split off for the monitoring ports.
However, as these TAPs have a copper or SFP-based monitoring output, 100%
signal strength is available by means of OEO conversion – i.e. conversion of
the optical signal into an electrical signal – in contrast to fiber-based
monitoring ports.
8. Data Diode Function
Data diodes ensure unidirectional communication and ensure that data traffic
can only flow in one direction.
Unidirectional network devices are typically used to ensure information
security or the protection of critical digital systems, such as industrial
control systems or production networks from cyber attacks.
Our TAPs work like a diode and do not allow access to the network via the
monitoring ports for security reasons.
By adding this further layer of security, it is therefore not possible to
compromise the network connection and the productive network.
9. Individually configured available
Due to the FPGA chipset on which our active TAPs are based, it is possible to programme these models according to customer-specific requirements. For example, TAPs with fixed operating mode and/or fixed speed, time stamping of outgoing packets, and much more.
10. DIP Switch Configuration
As shown in the figure on the left, the second and third switches are used to
select the operating mode.
The switches numbered 1, 4, 5, 6, 7 and 8 are ignored and left for future use.
The desired configuration should be set before plugging in the network cable.
If an invalid configuration has been selected, all LEDs on the unit light up
and the relay switches are not activated. In this case, switch off the unit
and check the DIP switches.
When changing the configuration by means of DIP switches, it is always
necessary to perform a restart by disconnecting the power supply so that the
new settings are activated!
In case of a restart, however, there is no interruption of the network
traffic!
10.1 Operating Mode Configuration
Please note that no matter which operating mode you set, the link speed of the
RJ45 monitoring port will always be negotiated with 1000Base-T. In the case of
a TAP with SFP monitoring port the link speed is negotiated with 1000Base-T,
1000Base-SX, 1000Base-LX or 1000Base-ZX, depending on the transceiver type.
When selecting the operating mode (switches 2 & 3), the configuration is as
follows:
10.2 Passive / Power Off Mode
If the power supply fails, the active network connection is not interrupted.
Only the devices connected to the monitoring port are no longer supplied with
data.
