MX2020 Power Subsystem Description
The MX2000 routers are available in -48 V and 240 V China DC power configurations, three-phase (delta
and wye) AC power configurations, and a single-phase power configuration. You can add additional power
to the rack as needed. The MX2020 router is configurable with up to four AC or DC power distribution
modules (PDMs) (two per subsystem), and up to eighteen AC or DC power supply modules (PSMs). The
PSMs connect to the top and bottom power backplanes that distribute the output voltages produced by
the PSMs to the router components.
Table 24 on page 92 describes the MX2020 DC power components and
the MX2020 AC power components.
