Page 40 Some FRUs draw power only from zone 0, some FRUs draw power only from zone 1, and some FRUs draw power from both zone 0 and zone 1. There are two types of DC power subsystems available for the MX2020: a “base” DC power subsystem (MX2020-BASE-DC) and an “optimized” or premium DC power subsystem (MX2020-PREMIUM2-DC).
Page 41 Figure 7: Power Distribution in an Optimized DC Power Subsystem DC PSMs—The MX2020 DC PSMs (-48 V) and DC PSMs (240 V China) are hot-removable and hot-insertable. The DC PSMs are a dual redundant feed (INP0 and INP1). To provide feed redundancy, you can connect each DC PSM to two separate feeds from different sources.
Page 42 (INP0 and INP1). One input feed is active during operation. These feeds are set by the input mode DIP switch located on the AC PSM (see MX2020 AC Power Supply Module Description). Each AC PSM works with a single phase derived from either three-phase delta 200-240 VAC (line-to-line) or three-phase wye 200-240 VAC (line-to-neutral).
Page 43 three-phase feeds to be connected. Each phase from each of the two feeds is distributed among one or two PSMs. One feed has each phase going to two PSMs, and the other feed has each phase going to a single PSM. The single-phase AC PDM provides an AC input connection from the single-phase AC power source, and also provides an input power interface to the PSM through a system power midplane.
Page 44 PSM. Cooling system—The cooling system in a fully-configured MX2020 router has a total of four fan trays, which are controlled by the host subsystem. If one of the fans fails, the host subsystem increases the speed of the remaining fans to provide sufficient cooling for the router.

Page 173: Calculating Power Margin For Fiber-Optic Cable
– P = –15 dBm – (–28 dBm) = 13 dB Calculating Power Margin for Fiber-Optic Cable After calculating a link's power budget, you can calculate the power margin (P ), which represents the amount of power available after subtracting attenuation or link loss (LL) from the power budget (P ).
Page 174: Understanding Fiber-Optic Cable Signal Loss, Attenuation, And Dispersion
– LL = 13 dB – 2 km (1 dB/km) – 5 (0.5 dB) – 2 (0.5 dB) – 0.5 dB = 13 dB – 2 dB – 2.5 dB – 1 dB – 0.5 dB = 7 dB The following sample calculation for an 8-km-long single-mode link with a power budget (P ) of 13 dB uses the estimated values from Table 41 on page 150...

Together these factors limit the transmission distance of multimode fiber compared with single-mode fiber. Single-mode fiber is so small in diameter that rays of light can reflect internally through one layer only. Interfaces with single-mode optics use lasers as light sources. Lasers generate a single wavelength of light, which travels in a straight line through the single-mode fiber.
