The MX2020 router has either one redundant PDM or two redundant PDMs. An AC power
cord on a redundant PDM is hot-insertable and hot-removable. When a redundant PDM
is powered down, the other PDM automatically assumes the entire electrical load for the
router. If you have only one PDM, you must power off the system before removing the
AC power cord.
