Cabling the Router for Power

After you have correctly cabled the SRP IOA, you must attach grounding and electrical
wires before you attempt system power-up. See Figure 27 on page 54.
Three main tasks are involved:
1.
CAUTION: Switches may have inadvertently flipped to ON during shipping and
installation.
2.
WARNING: Always connect the grounding wires first (before connecting the power
cables) and disconnect them last when installing or servicing the router.
