M10i DC Power Supply Description


A DC-powered router has up to four load-sharing DC power supplies, located at the bottom rear of the chassis, as shown in M10i Chassis Description. For information about power supply redundancy and replaceability, see M10i Power System Description.

The router must have at least two DC power supplies, and any two DC power supplies can provide full power to the router. DC system redundancy requires two power sources from feed A and two power sources from feed B. If one feed fails or is shut down for service, the other feed powers two DC power supplies and can provide full power to the router's components indefinitely.

Figure 1 shows the power supply and Electrical Specifications for DC Power Supply lists electrical specifications. For information about the LED, see M10i Power Supply LEDs.
