Page 89 Chapter 6: Cable Requirements Modal dispersion, which is the spreading of the signal over time caused by the different propagation modes in the fiber. For multimode transmission, modal dispersion, rather than chromatic dispersion or attenuation, usually limits the maximum bit rate and link length.

Page 93 Chapter 7: Planning Power Requirements NOTE: In North America, AC power cords must not exceed 4.5 meters (approximately 15 feet) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3). The cords separately orderable as FRUs are in compliance.

Chapter 7: Planning Power Requirements WARNING: The switch is pluggable type A equipment installed in a restricted-access location. It has a separate protective earthing terminal provided on the chassis in addition to the grounding pin of the power supply cord. This separate protective earth terminal must be permanently connected to earth ground.
Page 96 Dell PowerConnect J-Series J-EX8208 Ethernet Switch Hardware Guide Use Table 36 on page 80 if your switch has power management configured for N+1 power redundancy. Use Table 37 on page 80 if your switch has power management configured for N+N power redundancy.
Page 97: Calculating System Thermal Output For Your J-Ex8208 Switch Configuration
Chapter 7: Planning Power Requirements Calculate the maximum system power consumption by dividing the maximum internal power consumption by the efficiency of the power supply. This accounts for the loss of energy within the power supply. NOTE: The efficiency of a 2000 W AC power supply is approximately 90 percent when input voltage is high line (200–240 VAC).
Page 98 Dell PowerConnect J-Series J-EX8208 Ethernet Switch Hardware Guide To calculate the number of power supplies required for your switch configuration: Determine the power requirement of the chassis—with the fan tray, SRE modules, and SF module, but no line cards—by consulting Table 38 on page 82.
Page 99 Chapter 7: Planning Power Requirements NOTE: If the input voltage is high line (200–220 VAC), the output wattage of a 2000 W AC power supply is 2000 W. If the input voltage is low line (100–120 VAC), the output wattage of a 2000 W AC power supply is 1200 W.
