CAUTION: To meet safety and electromagnetic interference (EMI) requirements and to
ensure proper operation, you must connect PTX10000 routers to earth ground before
you connect them to power. For installations that require a separate grounding conductor
to the chassis, use the protective earthing terminal on the router chassis to connect to
earth ground. For instructions on connecting a PTX10000 router to ground using a
separate grounding conductor, see “Connecting Earth Ground to a PTX10000” on page 232.
NOTE: The battery returns of the JNP10K-PWR-DC power supply must be connected as an isolated
DC return (DC-I).
•
Ensure you understand how to prevent ESD damage. See “Prevention of Electrostatic Discharge Damage”
on page 427.
•
Ensure that you have the following parts and tools available to install a JNP10K-PWR-DC power supply:
•
Electrostatic discharge (ESD) grounding strap
•
DC power source cables (not provided) with the cable lugs (provided) attached
The provided terminal lugs in a PTX10000 are sized for either4 AWG (21.1 mm
2
) or 6 AWG (13.3
mm
2
) power source cables. When running all JNP10K-PWR-DC power supply modules in the chassis,
the DC power source cables that you provide must be 6 AWG (13.3
2
) mm²) stranded wire. We
recommend that you install heat-shrink tubing insulation around the crimped section of the power
cables and lugs.
NOTE: If you upgrade the JNP10K-PWR-DC to a JNP10K-PWR-DC2 and set the input mode
to high (80-A), you must use 4 AWG (21.1 mm²) stranded wire.
NOTE: See the heat symbol . Wear heat-resistant gloves while accessing the fan
tray and power supply.
