Replacing Power Supplies and Redundant Power Supplies
The Cisco 2010 CGR routers have replaceable power supplies. Use a Number 2 Phillips screwdriver to
remove or install the power supply.
Caution
Any combination of power supplies can be inserted into the chassis. Dual power supply configurations
are load sharing in redundancy mode.
A single power supply is sufficient for supporting power needs to the system; however, if a single PSU
is deployed it must be in slot 1 (PSU1).
Note
The power supplies are hot swappable. The power supply LED must show it is properly functioning
before removing the other power supply in the router.
