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.

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.
