Figure 204: Removing an MX2008 AC Power Supply Module
Installing MX2000 Router AC Power Supply Modules
Before you install a PSM, be aware of the following:
NOTE: The AC PSM is hot-swappable when a minimum number of PSMs installed and operational.
WARNING: The AC PSMs have no circuit breakers that can physically disconnect AC
current from the router. After AC feeds have been connected to the PDM, the AC
voltage is always present on the power midplane and is distributed to the PSM
connectors on the power midplane.
CAUTION: To maintain proper cooling and prevent thermal shutdown of the operating
PSM, each PSM slot must contain either a PSM or a blank panel. If you remove a PSM,
you must install a replacement PSM or a blank panel shortly after the removal.
