CiscoASR 9000 Series Aggregation Services Router Hardware Installation Guide
Chapter1 Preparing for Installation
Site Requirement Guidelines
For DC power cables, we recommend that you use 60-A-rated, high-strand-count copper wire cables.The
length of the cables depends on your router location from the source power. DC power cables are not
available from Cisco, but they are available from any commercial cable vendor.
You must terminate DC power cables using cable lugs at the power tray end. Ensure that the lugs are
dual-hole and that they fit over M6 terminal studs at 0.625-inch (15.88-mm) centers. For #4 AWG cable,
use Panduit part number LCD4-14AF-L or equivalent; for #6 AWG, use Panduit part number
LCD6-14AF-L or equivalent.
Warning
Hazardous voltage or energy may be present on power terminals. Always replace cover when
terminals are not in service. Be sure uninsulated conductors are not accessible when cover is in
place.
