Replacing Power System Components in a J6300 Router

The J6300 Services Router has one or two load-sharing AC power supplies
(see Figure 8), located at the right rear of the chassis. Each AC power supply
provides power to all components in the router. The AC power supplies are
fully redundant. If one power supply fails or is removed, the remaining power
supply instantly assumes the entire electrical load. One power supply can
provide full power for as long as the router is operational.
Each J6300 power supply is hot-insertable and hot-removable. To replace a power
supply in a J6300 router, use the following procedures:
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 567.
Press and release the power button to power off the Services Router. Wait
for the LED to turn off.
POWER ON
Unplug the power cord from the power source receptacle.
Unplug the power cord from the appliance inlet on the power supply faceplate.
Insert the appliance coupler end of the replacement power cord into the
appliance inlet on the power supply faceplate.
Insert the power cord plug into an AC power source receptacle.
Press and release the power button to power on the router. Verify that the
LED lights steadily after you press the power button.
POWER ON
Verify that the power cord does not block access to router components or
drape where people might trip on it.
