Replacing DC Power Supply Cables
To replace a power cable for a DC power supply:
1. Locate a replacement power cable and a lug that meet the specifications defined
in Chassis Grounding on page 123 and DC Power, Connection, and Power
Cable Specifications on page 111.
CAUTION: A licensed electrician must attach a cable lug to the power cable that you
supply. A cable with an incorrectly attached lug can damage the router (for example,
by causing a short circuit).
2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to the ESD point on the chassis, or to an outside ESD point if
the router is disconnected from earth ground. For more information about ESD,
see Preventing Electrostatic Discharge Damage on page 251.
3. Press and release the power button to power off the Services Router. Wait for
the POWER LED to turn off.
4. Ensure that the voltage across the DC power source cable leads is 0 V and that
the cable leads cannot become active during installation.
