Caution You cannot mix power supply types within the chassis. If you plan to replace a
2000 W PEM from an original system with a new 2400 W PEM, you must replace
all of the older PEMs and the power shelf (see Tabl e 7-1 on page 7-30). To
perform the upgrade, you must shut down the router. Be sure to notify the system
administrator and other appropriate personnel that all routing traffic stops while
the upgrade takes place.
