The Magnum ITS Blade Ethernet Switch, equipped with six 10/100 RJ-45 ports and
two 100Mb Fiber ports, easily connects to local Ethernet devices at the intersection such as
video cameras and the Model 2070 Controller, while two Ethernet 100Mb fiber optic ports
connect upstream to the TOC or to intermediate Ethernet switches in the traffic control network.
The Magnum ITS Blade, entirely contained in a standard 2070 Traffic Control Chassis, draws its
power from the 2070 chassis power supply. Noo 2070 chassis backplane signal pins are used
The ITS Blade module easily can be fitted into either a new or existing 2070 chassis
without creating any conflict with other installed modules. The Magnum ITS Blade
specifications comply with Caltrans and NEMA TS-2-1998 Standards for Traffic Controller
Assemblies.
The two “future-proof” fiber ports have been designed as full-duplex 100Mbps
switched fiber ports. Six copper (RJ-45) with full / half-duplex-10/100-auto-negotiating ports
are included. The Magnum ITS Blade Hardened Switches provide the switching speed and the
reliability to smoothly support streaming Ethernet traffic at 100Mbps or 10Mbps speed. The
optional fiber ports are normally configured and tested with the ITS Blade in the factory, and are
available in multi-mode and single-mode SC-type fiber connectors.
Designed specifically to operate in Model 2070 Traffic chassis in temperature
uncontrolled road side boxes, the Magnum ITS Blade can easily sustain the heat…. and the cold.
Armored with unique thermal techniques (patent pending) developed by GarrettCom
technologists extend the ambient temperature operating range beyond standard product ratings,

and improve operating lifetime and reliability. Ambient temperatures can be from -40°C to
+75°C. The extreme temperature Ethernet technology is derived from the proven design of the
companion products, the Magnum P62 Switch family, already widely in use in Traffic Control
Systems and other Outdoor Industrial Ethernet LAN applications.
The Magnum ITS Blade is available in three different TC62F models to suit
installations using multi-mode, single mode or combinations of these two connectors. All
models are specially designed for high reliability and EMI noise immunity.
2.3 100Mb Fiber ports, SC Connectors
The Fast Ethernet fiber switched ports on the Magnum ITS Blade operate at fixed 100Mb
speed and full-duplex mode for the best performance. The ITS Blade’s fiber ports are factory-
built as either a multi-mode or single-mode SC connectors. A yellow label on the fiber port
connector will indicate if it is single-mode . . . otherwise it is a multi-mode port. The 100Mbps
fiber ports are each a switched port and perform as a domain, providing a high bandwidth
backbone connection and supporting long (up to 20km single-mode, or 40km special “long-
reach”) fiber cable distances for installation versatility.
On each Magnum ITS Blade, there are three LED’s
for each of the RJ-45 switched ports. The F/H indicates full
duplex when ON; when it is OFF, operation is half-duplex.
One (LK/ACT) is steady ON to indicate LINK, and blinking
indicates the port is transmitting / receiving. The 10/100 LED
is ON for 100Mbps and OFF for 10 Mbps (when LINK is
made). For fiber ports, the LEDs are the same except no F/H
(and 10Mb is not possible).
A device must be connected to the other end of a
port’s cable and a proper link (LK lit) must be made with the device at the other end of the cable
in order for each LINK LED to provide a valid indication of operating conditions.
2.4 Frame Buffering and Latency
The Magnum ITS Blade is a store-and-forward switch. Each frame (or packet) is
loaded into the Switch’s memory and inspected before forwarding can occur. This technique
ensures that all forwarded frames are of a valid length and have the correct CRC, i.e., are good
packets. This eliminates the propagation of bad packets, enabling all of the available bandwidth
www GarrettCom com ..

Magnum ITS Blade Hardened Switches for 2070’s Installation and User Guide (02/03)
8
to be used for valid information.
While other switching technologies such as "cut-through" or "express" impose
minimal frame latency, they will also permit bad frames to propagate out to the Ethernet
segments connected. The "cut-through" technique permits collision fragment frames, which are
a result of late collisions, to be forwarded to add to the network traffic. Since there is no way to
filter frames with a bad CRC (the entire frame must be present in order for CRC to be
calculated), the result of indiscriminate cut-through forwarding is greater traffic congestion,
especially at peak activity. Since collisions and bad packets are more likely when traffic is
heavy, the result of store-and-forward operation is that more bandwidth is available for good
packets when the traffic load is greatest.
To minimize the possibility of dropping frames on congested ports, each Magnum ITS
Blade Hardened Switch dynamically allocates buffer space from its memory pool, ensuring that
heavily used ports receive very large buffer space for packet storage. (Many other switches
have their packet buffer storage space divided evenly across all ports, resulting in a small, fixed
number of packets to be stored per port. When the port buffer fills up, dropped packets result.)
This dynamic buffer allocation provides the capability for the maximum resources of the
Magnum ITS Blade to be applied to all traffic loads, even when the traffic activity is unbalanced
across the ports. Since the traffic on an operating network is constantly varying in packet
density per port and in aggregate density, the Magnum ITS Blade Hardened Switches are
constantly adapting internally to provide maximum network performance with the least dropped
packets.
When the ITS Blade Hardened Switch detects that its free buffer queue space is low,
the Switch sends industry standard (full-duplex only) PAUSE packets out to the devices sending
packets to cause “flow control”. This tells the sending devices to temporarily stop sending
traffic, which allows a traffic catch-up to occur without dropping packets. Then, normal packet
buffering and processing resumes. This flow-control sequence occurs in a small fraction of a
second and is transparent to an observer. See Section 4.6 for additional details.
Another feature implemented in Magnum ITS Blade Hardened Switch is a collision-
based flow-control mechanism (when operating at half-duplex only). When the Switch detects
that its free buffer queue space is low, the Switch prevents more frames from entering by forcing
a collision signal on all receiving RJ-45 half-duplex ports in order to stop incoming traffic.
The latency (the time the frame spends in the Switch before it is sent along or
www GarrettCom com ..

Magnum ITS Blade Hardened Switches for 2070’s Installation and User Guide (02/03)
9
forwarded to its destination) of the ITS Blade Ethernet Switch varies with the port-speed types,
and the length of the frame is a variable here, as it is with all store-and-forward switches. For 10
Mb-to-10 Mb or 10 Mb-to-100Mb or 100Mb-to-10 Mb forwarding, the latency is 15
microseconds plus the packet time at 10Mb. For 100Mb-to-100Mb forwarding, the latency is 5
microseconds plus the packet time at 100Mb.
2.5 Features and Benefits
100Mb switching services for high performance Ethernet LANs
Magnum ITS Blade provides Fast Ethernet switching on all ports. They perform
high-speed filter/forward operations on the traffic, giving each port’s segment a
full 100Mb (or possibly 10 Mb for RJ-45 ports) of bandwidth.
IEEE 802.1P QoS prioritization supports data and streaming traffic
Mixtures of bursty data packets and streaming packets for video are supported,
with priority use of the bandwidth given to streaming for best quality video.
Two “future-proof” fiber ports with SC connectors
Built-in fiber ports may be ordered with 100Mb full-duplex multi-mode SC,
single-mode SC, and (special order) SSCL-type connectors. The fiber ports are
set to full-duplex mode. No Media Converters needed.
All RJ-45 ports are auto-negotiating, and auto-crossover
RJ-45 ports support twisted pair “copper” segment connections, with 10 or
100Mb speed and full / half-duplex mode selected by Ethernet standard IEEE
802.3u auto-negotiation. Auto-crossover is standard.
Front-mounted LEDs for convenient viewing
The LEDs that indicate operating status are on the top of the unit for easy
viewing in any situation. As the units are vertically mounted in 2070 Box, Front-
surface viewing is convenient for the user to see the status.
Installation is “Plug and Play”, operation is transparent to software
The Magnum ITS Blade operates as a hardened switch, only forwarding those
packets from each domain that are needed on the other domains. Internal address
tables are self-learning, enabling users to change port connections or 10/100
domains without affecting operations.
Thermal design techniques for use in temp. uncontrolled applications
The ITS Blade’s advanced thermal techniques extend the ambient temperature
operating range beyond standard product ratings, and improve operating lifetime
and reliability.

2.6 Applications
The ITS Blade is designed specifically for harsh temperature environments and brings
future-proof fiber and widely used copper connectivity to out-of-the-way sites and outdoors.
Example 1. Magnum ITS Blade In this example, a Magnum ITS Blade Hardened Switch
serves real time roadside traffic data collection and transmits it to a remote control station over
fiber. Since multiple traffic control sites here are a long distance apart, they are all connected in
series to each other and to the central station or TOC.
Some local users (using RJ-45 ports) may operate at 100Mbps, and some users and
utility devices may run at 10 Mbps. A Magnum ITS Blade Hardened Switch serves this
requirement economically and efficiently. The six full- and half-duplex switched ports make the
required setup simple for collection of traffic data, including streaming video from one or more
cameras. The advanced thermal techniques enable operation in un-controlled outdoor
temperatures, and provide high reliability of the ITS Blade, make it suited to the roadside site.
The two 100Mbps full-duplex fiber ports fulfill the long distance connection need, and provid

3.0 INSTALLATION
This chapter provides instructions for installing Magnum ITS Blade units.
3.1 Locating Magnum ITS Blade, 10/100Mb Hardened Switch
The location of a Magnum ITS Blade Hardened Switch is designed primarily for the
specific application, such as road traffic data collection and control stations, the Magnum ITS
Blade draws the power from 2070 chassis for high reliability and convenience in out-of-the way
locations. Entirely contained in a standard 2070 Traffic controlled chassis, the ITS Blade easily
deploy in temperature un-controlled roadside boxes, and can sustained the heat. …and the cold.
The front mounted LEDs are easily viewable to see the data traffic and the port status.
3.2 Connecting Ethernet Media
The Magnum ITS Blade Hardened Switches can be connected to the following three
media types: 100BASE-TX, 10BASE-T and 100BASE-FX. CAT 5 cables should be used when
making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 may be
used. In either case, the maximum distance for unshielded twisted pair cabling is 100 meters
(328 ft). For fiber port 100BASE-FX multi-mode, 50/125 or 62.5/125 microns cabling can be
used, whereas for single-mode, 9/125 microns cabling should be used. Fiber cabling supports
much longer cable distance and higher bandwidths as compared to copper wiring.
Media IEEE Standard Connector
Twisted Pair (CAT 3 or 5) 10BASE-T RJ-45
Twisted Pair (CAT 5) 100BASE-TX RJ-45
Fiber (Multi-mode) 100BASE-FX SC
Fiber (Single-mode) 100BASE-FX SC
NOTE: It is recommended that high quality CAT. 5 cables (which work for both 10 Mbps and
100Mbps) be used whenever possible in order to provide flexibility in a mixed-speed
network, since P80-series switch ports are auto-sensing for either 10 and 100Mbps.
Note that the auto-sensing function does not sense the cable type.
3.2.1 Connecting Twisted Pair (RJ-45, CAT 3 or CAT 5, Unshielded or
Shielded)
The following procedure describes how to connect a 10BASE-T or 100BASE-TX
twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded
and shielded twisted pair cables.

1. Using standard twisted pair media, insert either end of the cable with a RJ-45 plug into
the RJ-45 connector of the port. Note that, even though the connector is shielded, either
unshielded or shielded cables and wiring may be used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure proper connectivity by noting that the LED will be
illuminated when the unit is powered and proper connection is established. If this does
not help, ensure that the cable is connected properly and that the device on the other end
is powered and is not defective.
4. For Port # 1 or 1SW, if the LINK LED is not illuminated, move the switch, which has a
crossover or up-link for linking to another hub or Switch.
3.2.2 Connecting Fiber Optic SC-type, "Snap-In"
The following procedure applies to installations using SC-type fiber connectors. This
procedure applies to ports using multi-mode SC fiber connectors.
1. Before connecting the fiber optic cable, remove the protective dust cap / plug from the
end of the fiber connectors, exposing the ports opening. Save the dust cover / plug for
future use in case the fiber cable needs to be unplugged for service.
2. Wipe clean the ends of the dual connectors with a soft cloth or lint-free lens tissue
dampened in alcohol. Make certain the connectors are clean before connecting. Then,
insert the square male connector into the SC female jack of the Fiber port connector until
it clicks and secures.
Note: One strand of the duplex fiber optic cable may be coded using color bands
at regular intervals; you should use the color-coded strand on the associated ports at
each end of the fiber optic cable segment.
3. Connect the Transmit (TX) port on the Magnum Fiber port to the Receive (RX) port of
the remote device. Begin with the color-coded strand of the cable for this first TX-to-RX
connection. Note – the two male square-end SC cable strands may be fastened together
to plug as a unit.
4. Connect the Receive (RX) port to the Transmit (TX) port of the remote device. Use the
non-color coded fiber strand for this.

The LINK LED for the fiber connector will illuminate when a proper connection has
been established at both ends (and when power is ON in the unit). If LINK is not lit after
cable connection, the normal cause is improper cable polarity. Swap the fiber cables at
the fiber connector to remedy this situation.
3.2.3 Connecting Fiber Optic ST-type, “Snap-In” (Optional)
The following procedure applies to installations using ST-type fiber connectors, i.e.,
using multi-mode ST.
When connecting fiber media to ST connectors, simply twist on the two round male
connectors into the ST female jacks of the Fiber connector until it clicks and secures.
3.2.4 Connecting Single-Mode Fiber Optic
When using single-mode fiber cable, be sure to use single-mode fiber port connectors.
Single-mode fiber cable has a smaller diameter than multi-mode fiber cable (9/125 microns for
single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx are the diameters of the
core and the core plus the cladding respectively). Single-mode fiber allows full bandwidth at
longer distances, about 20Km with the single-mode SC.
The same procedures as for multi-mode fiber apply to single-mode fiber connectors.
Follow the steps listed in Section 3.2.2 above.
3.2.5 Power Budget Calculations for ITS Blade Fiber Media
Receiver Sensitivity and Transmitter Power are the parameters necessary to compute
the power budget. To calculate the power budget of different fiber media installations using
Magnum products, the following equations should be used:
OPB (Optical Power Budget) = P
T
(min) - P
R
(min)
where P
T
= Transmitter Output Power, and P
R
= Receiver Sensitivity
Worst case OPB = OPB - 1dB(for LED aging) - 1dB(for insertion loss)
Worst case distance = {Worst case OPB, in dB} / [Cable Loss, in dB/Km]
where the “Cable Loss” for 62.5/125 and 50/125µm(m.m.) is 2.8 dB/km,
and the “Cable Loss” for 100/140 (Multi-mode) is 3.3 dB/km,
and the “Cable Loss” for 9/125 (Single-mode) is 0.5 dB/km
The following data has been collected from component manufacturer’s (HP’s and Siemens’) web
sites and catalogs to provide guidance to network designers and installers.

* Note: The use of either multi-mode or single-mode fiber to operate at 100Mbps speed over
long distances (i.e., over approx. 400 meters) can be achieved only if the following
factors are both applied:
• The 100Mb fiber segment must operate in full-duplex (FDX) mode, and the worst-
case OPB of the fiber link must be greater than the fiber cable’s passive
Attenuation.
(Attenuation = Cable loss + LED aging loss + Insertion loss + safety factor)
3.2.6 Connections to NIC’s to support Auto -Negotiation, RJ-45
ports
The copper ports of Magnum ITS Blade Hardened Switches will function properly
with NICs (Network Interface Cards) which support Auto-Negotiation, and the Fast Link Pulse
(FLP) coding for the 100BASE-TX signaling system. When connecting a NIC to a ITS Blade, it
may be necessary to reload the NIC drivers on the user device if the NIC has been
communicating with a protocol other than 100BASE-TX (such as 10BASE-T). When 100Mb
speed is agreed and in use, the 10/100 LED is steady ON. It is OFF if there is no traffic or if 10
Mbps traffic.
3.3 Powering the Magnum ITS Blade Switches
The Magnum ITS Blade is powered up from the A1 or A2 backplane of a
standard 2070 Traffic Controller chassis. The ITS Blade will draw about 1.9A from 5VDC at pin
29 of the backplane connector. The PWR led will turn GREEN as soon as the power is applied
to the ITS Blade. Once received enough required power from the backplane, the ITS Blade will
become operational.
Power Input Voltage: 5VDC at 1.9Amps, 2070 backplane pins ABC29 per TEES 03/02
Power Consumption: 8 watts typical, 10 watts maxm.

4.0 OPERATION- the function and operation of the Magnum ITS Blade
Switches.
4.1 Dual-Speed Functionality, and Switching
The Magnum ITS Blade Hardened Switch provide six 10/100 RJ-45
switched ports, and two 100Mb fiber ports. The architecture supports a dual speed-switching
environment, with two built-in full-duplex “future-proof” fiber ports. The six RJ-45 copper ports
equipped with auto-negotiation capability.
The switched RJ-45 ports are full / half duplex and auto-sensing for speed. (See
section 2.2). When the connected device is 10 Mbps, the ITS Blade obeys all the rules of 10
Mbps Ethernet configurations. The 10 Mbps users share a 10 Mbps traffic domain, and can
“communicate with” 100Mbps users as well as 100Mbps domain. Similarly, the 100Mbps traffic
obeys the rules of 100Mbps Ethernet, and can communicate with 10Mb domain too.
All Magnum ITS Blades are plug-and-play devices. There is no software
configuration to be done at installation or for maintenance. The Half / full duplex mode for the
RJ-45 switched RJ-45 ports is user dependent and changes (by auto-negotiation) to full or half
duplex as the unit attached with these ports. The internal functions of ITS Blade are described
below.
Switching, Filtering and Forwarding
Each time a packet arrives on one of the switched ports, the decision is taken to either
filter or to forward the packet. Packets whose source and destination addresses on the same port
segment will be filtered, constraining them to one port and relieving the rest of the network from
processing them. A packet whose destination address is on another port segment will be
forwarded to the appropriate port, and will not be sent to the other ports where it is not needed.

Packets needed for maintaining the operation of the network (such as occasional multi-cast
packets) are forwarded to all ports.
The Magnum ITS Blade Switch operate in the store-and-forward switching mode,
which eliminates bad packets and enables peak performance to be achieved when there is heavy
traffic on the network.
Switching, Address Learning
The Magnum ITS Blade has address table capacity of 16K node addresses, and are
suitable for use in large networks. They are self-learning, so that as nodes are added or removed
or moved from one segment to another, the ITS Blade automatically keeps up with node
locations.
An address-aging algorithm causes least-used addresses to fall out in favor of new
frequently used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Auto-negotiation and Speed-sensing
All six RJ-45 ports independently support auto-negotiation for speed in 10BASE-T
and 100BASE-TX modes. Operation is according to the IEEE 802.3u standard.
When a RJ-45 cable connection is made, and each time a LINK is enabled, auto-
negotiation takes place. The ITS Blade advertises its capability for 10 or 100 Mbps speed, and
the device at the other end of the cable should similarly advertise / respond and both sides will
agree to the speed being used. Depending upon the device connected, this will result in
agreement to operate at either 10 Mbps or 100Mbps speed.
When the ‘LK/ACT’ LED is ON, steady ON indicates LINK with no traffic, blinking
ON indicates the port is transmitting / receiving. The port has auto-negotiated for operation. (If
a ITS Blade RJ-45port is connected to a non-negotiating device, it will default to 10 Mbps speed
and half-duplex mode, per the IEEE 802.3u standard).
4.3 Auto-crossover feature on RJ-45 ports
All six RJ-45 ports have the auto-crossover feature. MDI vs. MDIX connections are
automatically sensed and correctly handled. There is no up-link switch on any port. Any RJ-45
port can be connected either to a NIC or to a switch / hub port using standard twisted pair cables.
No crossover cables are required
