DC-Powered Router
Connections to DC power modules are rated at 60 A maximum. The system accepts a nominal input voltage
of –48 VDC with an operational tolerance range of –40 VDC to –72 VDC. One dedicated, commensurately
rated DC power source is required for each power module connection.
Power redundancy requirements vary based on the system configuration (number and type of line cards,
etc.). DC-powered systems are N+1 protected. A minimum of two power supplies are required for
redundant operation. Refer to the Cisco ASR 9000 Power Calculator to determine actual redundancy
requirements for any given configuration. See:
Power connections to the power tray for each DC power module requires four cables: two source cables
and two return cables. In addition, each DC power tray requires one earth ground, so the minimum
number of cables for connecting a single DC power module in a power tray is five (two source, two
return, one ground).
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.
