Cisco ASR 1006 Router –48 VDC Power Supply (ASR1013/06-PWR-DC)
Note
Shielded cables must be used to connect to the DB-25 alarm connector on both the AC and DC
power supplies in order to comply with the FCC/EN55022/CISPR22 Class A emissions
requirements. See the
“How Cisco ASR1000-RP Alarm Monitoring Works” section on
page 2-20
.
Before you begin the procedure to connect DC input power, read these important notices:
•
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 –48
V 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 the 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.
