Cisco ASR 1004 Hardware Installation Guide

•
For DC input power cables, select the appropriate wire gauge based on the National Electrical Code
(NEC) and local codes for 40-amp service at nominal DC input voltage (–48/–60 VDC). Three pairs of
cable leads, source DC (–) and source DC return (+), are required for each power distribution unit (PDU).
These cables are available from any commercial cable vendor. All input power cables for the chassis
should have the same wire gauge and cable lengths should match within 10 percent of deviation.
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.
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.
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 Figure 50: DC Input Power Cable Lug , on page 171) and
able to fit over M6 terminal studs at 0.625 inch (15.88mm) centers. Recommended lug terminal wire size

To avoid hazardous conditions, all components in the area where DC input power is accessible must be
properly insulated. Therefore, before installing the DC cable lugs, be sure to insulate the lugs according
to the manufacturer’s instructions.
Note
When you install the unit, the ground connection must always be made first and disconnected last. Statement
