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.
See Chapter 11, System Specifications for the power requirements for the
E-series router. Table 6-3 identifies the power input module cabling
requirements, and Figure 6-4 shows the main components of a power
input module.
