Cisco Systems Cisco ASR 1006 quick start Unit. Statement

Warning	This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence of
	a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if
	you are uncertain that suitable grounding is available. Statement 1024
Warning	This unit might have more than one power supply connection. All connections must be removed to de-energize the
	unit. Statement 1028
Warning	This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that the
	protective device is rated not greater than: AC power supplies 20 A and DC power supplies 40 A. Statement 1005

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.
