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.

Three main tasks are involved:

Switch all router power switches to OFF.

Caution: Switches may have inadvertently flipped to ON during shipping and installation.
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 router.
Connect the power cables to the PDUs.

See System Specifications for the power requirements for the router. Table 9 identifies the cabling requirements.

Table 9: E320 Router PDU Cables and Wires Needed

Cable/Wire	From	To
One 6-AWG ground wire	PDU ground terminal	Termination ground
Two 4-AWG wire leads	PDU Power A –48 VDC and RTN leads	Appropriate leads on power source No.1
Two 4-AWG wire leads	PDU Power B –48 VDC and RTN leads	Appropriate leads on power source No.2

Figure 27 shows the main components of a PDU.
