Figure 13: Installing an AC Power Supply
Upgrading the MX240 and MX480 DC Power Supplies
Removing the MX240 and MX480 DC Power Supplies
NOTE: The minimum number of power supplies must be present in the router
at all times.
WARNING: Before performing DC power procedures, ensure that power is
removed from the DC circuit. To ensure that all power is off, locate the circuit
breaker on the panel board that services the DC circuit, switch the circuit
breaker to the off position, and tape the switch handle of the circuit breaker
in the off position.
CAUTION: To maintain proper cooling and prevent thermal shutdown of the
operating power supply unit, each power supply slot must contain either a
power supply or a blank panel. If you remove a power supply, you must install
a replacement power supply or a blank panel shortly after the removal.
NOTE: After powering off a power supply, wait at least 60 seconds before
turning it back on.
