If the master host subsystem (or either of its components) fails, the backup can take over as the master. DC power subsystem—The MX2020 DC power system is made up of two subsystems. Each subsystem provides power to ten line card slots, one local fan tray and critical FRUs.
Page 33: Figure 2: Dc Power Subsystem Feed Redundancy
“MX2020 DC Power Supply Module Description” on page AC power subsystem—The MX2020 supports connection of a three-phase AC power system. There are two types of three-phase power systems: the three-phase delta and three-phase wye. The AC power going to the PSMs is split into three individual phases—each PSM works on a single phase.
Page 34: Figure 4: Power Distribution From Three-Phase Feed Wye Pdm To The Ac
NOTE: This is the minimum required to provide 2.5KW per PSM. Based on facilities guidelines, you should over-provision the MX2020 router. The two numbers listed in the current columns reflect the distribution of phases from the feed to PSM. For example, from one feed each phase goes to two PSMs and from other feed each phase goes to only one PSM.
