Figure 7-18 Cisco ASR 1004 Router –48 VDC Power Supply
Note Shielded cables must be used to connect to the DB-25 alarm connector on both the AC and –48 VDC
power supplies in order to comply with FCC/EN55022/CISPR22 Class A emissions requirements. See
the “How Cisco ASR1000-RP Alarm Monitoring Works” section on page 2-20.
Before you begin, read these important notices:
• The color coding of the –48 VDC input power supply leads depends on the color coding of the –48
VDC 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 –48 VDC input power supply matches lead color
coding used at the –48 VDC power source.
• For –48 VDC input power cables, select the appropriate wire gauge based on the National Electrical
Code (NEC) and local codes for 60-amp service at nominal –48 VDC 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.
