Understanding Redundant Power Supplies

Chapter 38: Monitoring Redundant Power Supplies

M160 Router Redundant Power Supplies

The M160 router uses DC power. Two load-sharing, pass-through power supplies are 
located at the bottom rear of the chassis. Figure 205 shows the M160 router power 
supplies and where they are installed in the chassis.

When the power supplies are installed and operational, they automatically share the 
electrical load. If a power supply stops functioning for any reason, the remaining 
power supplies instantly begin providing all the power the router needs for normal 
functioning, and can provide full power indefinitely.
