* 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.
