e: The use of either multimode or singlemode 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 100Mbps 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)
5.3.5 Connections to NICs, Supporting Auto-negotiation, RJ45 Ports
The copper ports of ProSwitch-Xtreme 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 ProSwitch-Xtreme, 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 100Mbps speed is
agreed and in use, the 10/100 LED is steady ON. It is OFF if there is no traffic or if 10Mbps traffic.

Powering the Xtreme Series
5.4.1 Powering the Xtreme-5V with External AC Power Supply
The rugged ProSwitch-Xtreme, mainly used in Industrial and Outdoor Ethernet applications at extended
temperatures, also supports universal AC power input from 85-275 vac 50-60Hz through a separate Power Source
unit. The wide range of AC power input qualifies this product for use worldwide, in almost any temperature
environment. The AC power source provides a rugged power supply enclosed in a metal case that also acts as a heat
sink, enabling extended application temperatures to be accommodated. The power supply also includes surge
protection to withstand AC power input upsets, such as might result from nearby lightening strikes. Shock and
vibration characteristics enable use in transportation applications such as ships, trains and roadside boxes. The DC
power output cord comes with a military-style screw-lock female plug for secure attachment to the ProSwitch-Xtreme-
5V Switch.
Input Voltage
: 85-264 VAC, 47-63HZ, Auto-ranging
AC Power Connector
: IEC-type, male recessed
Power Output
: 5VDC, 3Amps max
Input Fuse for overload and short protection
: 3AG type, 0.5 Amp; spare is included
Power Capacity
: 15 watts output, 70% min efficiency
Surge Protection
: over 150 joules, with clamping at 800V 50A min.
Operating Shock and Vibration
: meets Bellcore GR-63-CORE Sections 4.4.1 and 4.4.3
NOTE
:
For best results at high-temperature, fasten the metal case of the power supply to be in contact with
a vertical surface (such as pedestal) that has good heat conducting properties. Remove rubber “feet”, if
present, to enhance metal-to-metal contact and provide the best heat transfer away from the unit.

Cable Strain Relief Feature on all Xtreme Models
The ProSwitch-Xtreme switches are designed to use in harsh environments. The extended temperature
features qualify them to be used in roadside traffic data collection and control stations, high temperature industrial
plants, plenums and ceiling locations in commercial buildings, etc. They are usually mounted vertically so that the
cables hang out the bottom. There is a cable strain relief feature provided as part of the package design.
The ProSwitch-Xtreme switches have a tie wrap holder as part of the base plate of the unit for use for cable
strain relief. The strain-relief feature is applicable to power cables as well as to Ethernet cables, both twisted-pair
copper and fiber. Cable tie-wraps can secure the cables and can be attached to the base plate HOOK provided at the
bottom-front of the unit. In the event that the attached cable is pulled, the tie-wrap cable strain relief feature protects
the cable connection from coming loose. This feature provides a more reliable and robust installation and operation.
