Juniper MX104 - Connecting DC Power Cables to the MX104 Router

Connecting DC Power Cables to the MX104 Router
To connect power to the router, you need the following tools:
•
Phillips (+) screwdriver, number 2
•
ESD grounding wrist strap
•
Grounding ring lug with hole sized for an M5 screw
•
M5 nut and washer (one per DC power supply, attached)
•
DC power source cables, minimum 14 AWG or as required by local code (not provided)
•
DC power ring lugs, Panduit PV12-14HDRB-2k (two per DC power supply)
•
M6 screws and washers (two per DC power supply, attached)
•
Grounding cable, minimum 14 AWG or as required by local code (not provided)
The DC power supply has one grounding point and two terminals on each power supply,
covered by a clear plastic cover.
WARNING: You must ground the router before connecting the DC power
cables.
To connect the power cables:
1. Switch off the dedicated customer site circuit breakers. Ensure that the voltage across
the DC power source cable leads is 0 V and that there is no chance that the cable
leads might become active during installation.
2. Ground the DC power supply (see Figure 28 on page 118):
a. Remove the nut and washer from the grounding point on the power supply.
b. Secure each grounding cable lug to the grounding point with the washer and nut.
