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 gen12 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 opera5 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.
