Cabling The E-Series Router For Power - Juniper E-Series Installation And User Manual

Cabling the E-Series Router for Power

After you have correctly cabled the modules and I/O modules, you must
attach grounding and electrical wires before you attempt system
power-up. There are three main tasks involved:
1
Switch all E-series router power switches to OFF.
Caution: Switches may have inadvertently flipped to ON during shipping and
installation.
2
Connect the grounding wires to the chassis.
Warning: Always connect the grounding wires first (before connecting the power
cables) and disconnect them last when installing or servicing the E-series router.
3
Connect the power cables (AC or DC) to the power input modules.
