conductor to the chassis, use the protective earthing terminal on the router chassis to
connect to earth ground. For instructions on connecting an MX10004 router to ground
using a separate grounding conductor, see
"Connect the MX10004 Router to Earth
.
NOTE: The battery returns of the JNP10K-PWR-DC2 power supply must be connected as an
isolated DC return (DC-I).
• Review how to prevent ESD damage. See
"Prevention of Electrostatic Discharge Damage" on page
• Ensure that you have the following parts and tools available to install a DC power supply:
• Electrostatic discharge (ESD) grounding strap
• High-current cable assembly CBL-PWR2-BARE (not provided) with the cable lugs (provided)
attached and with heat-shrink tubing insulation around the crimped section of the power cables
and lugs
The provided terminal lugs for the JNP10K-PWR-DC2 (Panduit LCD4-14A-L, or equivalent) and
sized for 4 AWG (21.1 mm
2
) power source cables
Power source cables as 4 AWG (21.1 mm²) stranded wire that is rated 75° C or per local electrical
code
• 13/32 in. (10 mm) nut driver or socket wrench
• Phillips (+) screwdrivers, numbers 1 and 2
• Multimeter
To install a JNP10K-PWR-DC2 power supply in an MX10004:
1.
Wrap and fasten one end of the ESD grounding strap around your bare wrist and connect the other
end of the strap to an ESD point on the chassis. An ESD point is located next to the protective
earthing terminal and below PSU 5 on the rear of the MX10004 (see
2.
Taking care not to touch power supply components, pins, leads, or solder connections, remove the
power supply from its bag.
3.
Peel back and remove the protective plastic wrap that covers all four sides of the power supply.
4.
Ensure that the power switch is set to the standby (O) position. This switch turns off the output
voltage; it doesn’t interrupt DC.
