Page 71: Appendix C Cabling Recommendations
Appendix C Cabling recommendations When a UTM device is mounted in a 19-inch standard rack, the interface cables are routed through the cable management brackets, bound at cabling racks on chassis sides, and then routed up or down to pass through the chassis top or the raised floor, depending on the available equipment room condition. The power cables run along the two sides of the chassis and out of the chassis either from the chassis top or the raised floor depending on the equipment room conditions (power distribution cabinet, lightning protection box, connector strip, and so on) of the exchange office. - Page 72 Figure 49 Correct and incorrect cable binding Route different types of cables (for example, power cables and signal cables) separately. If they • are close to one another, cross them over one another. If you route them in parallel, make sure the space between a power cable bundle and a signal cable bundle is at least 30 mm (1.18 in).
- Page 73 Figure 51 Binding cables where they must be bent Route, bind, and attach excess cables for easy, safe maintenance activities and proper operations. • Do not tie power cables to slide rails. • When you connect a cable to an articulated part, for example, when you connect a grounding •...

Page 77: Appendix E Cables
Appendix E Cables Ethernet twisted pair cable Introduction An Ethernet twisted pair cable consists of four pairs of insulated copper wires twisted together. Every wire uses a different color, and has a diameter of about 1 mm (0.04 in). A pair of twisted copper cables can cancel the electromagnetic radiation of each other, and reduce interference of external sources. - Page 78 Figure 55 RJ-45 connector pinout diagram NOTE: The RJ-45 Ethernet interfaces use category 5 or higher Ethernet twisted pair cables for connection. EIA/TIA cabling specifications define two standards, 568A and 568B, for cable pinouts. • Standard 568A—pin 1: white/green stripe, pin 2: green solid, pin 3: white/orange stripe, pin 4: blue solid, pin 5: white/blue stripe, pin 6: orange solid, pin 7: white/brown stripe, pin 8: brown solid.
