Cisco ASR 1001 Router Overview and Installation

Power Supplies in the Cisco ASR 1001 Router

The Cisco ASR 1001 Router power supply module supports the following Cisco power supplies:
• AC power supply operates between 85 to 264 VAC
• –48 VDC power supply input range supported is -40.5 to -72 VDC.
The power supply generates +12 V and +5 V, which is distributed to the mainboard and fans. The +5 V is
used to operate the power control devices. It also provides an operational +5 V, as needed.
The power supply units contain one or two fans that are only used for cooling the power supply. Each power
supply is self contained and controls its own fan speed and fan redundancy.
The power supplies are hot pluggable from the rear of the chassis and can be removed or installed while the
system is operating, without affecting any aspect of system performance. The Cisco ASR 1001 Router supports
up to seven chassis-mounted cooling fans. Each fan provides an alarm output for error indication speed
measurement. The fans are not field replaceable, but the system can meet the cooling requirements in the
event of a single-fan failure.

AC Power Supply for Cisco ASR 1001 Router

The AC power supply input inlet is an IEC connector. The current rating on the connector is 10 A. The AC
power supply is secured into the chassis with two captive screws mounted on the faceplate.
The following image shows the AC power supply for the Cisco ASR 1001 Router.

--48 VDC Power Supply for Cisco ASR 1001 Router

The –48 VDC power supply input connector accepts a Euro-style terminal block. It is compliant with safety
agencies' guidelines and electrical requirements of the supply. The DC power supply operates within
specification from –40.5 to –72 VDC continuously once the power supply DC input reaches the threshold of
–43.5 V.
The –48 VDC power input connector Euro-style terminal block will accept three wires: one positive polarity,
one negative polarity, and one ground wire. The connection order is negative (–), positive (+), and GND. The
DC power supply is secured into the system chassis with two captive screws mounted on the faceplate.
