Installing a DC Power Supply in a J6350 Router

Each power supply in a DC-powered router must be connected to earth ground.
A ground terminal is provided on each DC power supply for this purpose.
To install a DC power supply in a J6350 Services Router (see Figure 50):
1.
CAUTION: There is no standard color coding for DC power cables. The color coding
used by the external DC power source at your site determines the color coding
for the leads on the power cables that attach to the terminal studs on each power
supply. You must ensure that power connections maintain the proper polarity. The
power source cables might be labeled
2.
3.
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.
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 205.
Using both hands, slide the power supply into the chassis until you feel
resistance.
Firmly push the power supply into the chassis until it comes to a stop. Make
sure that the power supply faceplate is flush with any adjacent power supply
faceplate.
