The MX104 router uses either AC or DC power supplies (see
Figure 16 on page 62). The power supplies are located in the front of the chassis and offer
1+1 redundancy. Each power supply has a handle, an ejection tab, and a status LED.
CAUTION: The router cannot be powered from AC and DC power supplies
simultaneously.
When two power supplies are present, they share power almost equally within a fully
populated system. If one power supply in a redundant configuration fails or is removed,
the remaining power supply assumes the entire electrical load without interruption. A
single power supply provides the maximum configuration with full power for as long as
the router is operational. A second power supply can be installed for redundancy. Each
power supply is cooled by its own internal cooling system.
