Installation Procedures: Route and Attach Overhead Wiring
InfraStruXure System—Installation and Start-Up 43
Route and attach power cables to equipment racks
If you ordered overhead wiring, connect the prewired power cables of the InfraStruXure PDU as
follows:
1. Install the Shielding Troughs, Shielding Partitions, and Cable Ladders so that you can route
power cables from the PDU to the NetShelter VX Enclosures.
2. Find the numbers that indicate the enclosure to which each power cable will supply power.
These numbers appear on the roof of the PDU where the power cables exit, and on the ends of
each power cable.
3. Beginning with the power cables for the enclosures farthest from the PDU, run each power
cable within the Shielding Trough along the row and, if necessary, across one or more Cable
Ladders to the enclosure to which it will provide power.
4. Connect the appropriate power cable to APC power management equipment in the enclosure in
one of the four following ways:
–For single-feed devices without redundancy: attach a power cable directly to a Rack PDU
installed in a NetShelter VX Enclosure.
For installation instructions, see page 39.
Note
The enclosures are not numbered. Consult your APC InfraStruXure
Configuration Build-out Tool to determine the enclosure associated with each
power cable.
Note
Ensure that the L21-20 twist-lock connector at the end of each power cable
always lies on top of any longer power cables in the Shielding Trough.
