Step 4: Connect Power Cables
Depending on the configuration, your router uses either AC or DC power supplies. Perform the appropriate procedures for each

two power supply modules. The power supplies install in the rear of the chassis in the slots provided.
WARNING:
You must ground the router before connecting either the AC power cord or the DC power cable.
CAUTION:
Do not mix AC and DC power supplies in the same chassis. Similarly, do not mix different airflow
modules(AFO and AFI) in the same chassis.
