Cisco ASR 1006 Router Overview and Installation
Each DC input power cable is terminated at the PDU by a cable lug. The cable lugs must be
dual-hole, and have a straight tongue. They must be able to fit over 1/4-inch terminal studs at
0.625-inch (15.88-mm) centers.
Note
A ground cable is required for each DC PDU. We recommend that you use at least 6-AWG
multistrand copper wire. This wire is not available from Cisco Systems; it is available from any
commercial cable vendor.
The ground wire cable lug should be dual-hole (see
studs at 0.625 inch (15.88mm) centers. Recommended lug terminal wire size Panduit part number:

DC input power cables must be connected to the PDU terminal studs in the proper positive
(+) and negative (–) polarity. In some cases, the DC cable leads are labeled, which is a
relatively safe indication of the polarity. However, you must verify the polarity by measuring
the voltage between the DC cable leads. When making the measurement, the positive (+)
lead and the negative (–) lead must always match the (+) and (–) labels on the power
distribution unit.

accessible must be properly insulated. Therefore, before installing the DC cable lugs, be sure
to insulate the lugs according to the manufacturer's instructions.
