Note The grounding architecture of this product is DC-isolated (DC-I) for DC-powered products.

DC-powered products have a nominal operating DC voltage of 48 VDC. Minimal steady state DC

operating voltage is 19.2 VDC.

LEDs

The Cisco ASR 901 10G chassis and interface modules contain LEDs to assist in troubleshooting. For

more detailed description of the LEDs, see the “Reading the LEDs, page A-4.

Power Supply

The Cisco ASR 901 10G router is equipped with an internal -24/-60 Volts Direct Current (VDC). The

router is provided with a single AC power supply or DC (1+1 Redundant) power supply. The power input

connectors are located at the front left-side side of the router. The DC power connector has the standard

A and B feeds for DC redundancy. The DC power supply is compatible with the range of DC input

voltages specifically available at cell sites.

See Table 1 -1 for the DC power supply specifications and Tabl e 1-2 for the AC power supply

specifications.

Safety Precautions

Observe the following general safety precautions and recommendations in planning the source power

requirements for the CiscoASR 901 10G router (for additional safety information, see the “Safety
