Read these important notices before you install the DC-input power supply in the Cisco ASR1006 router:

•The color coding of the DC-input power supply leads depends on the color coding of the DC power source at your site.

Typically, green or green/yellow is used for ground (GND), black is used for -48V on negative (–) terminal and red is used

for RTN on the positive (+) terminal. Make certain the lead color coding you choose for the DC-input power supply matches

lead color coding used at the DC power source.

•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.
