The chassis has a front-to-rear airflow. Six internal fans draw cooling air into the chassis and across internal
components to maintain an acceptable operating temperature. The fans are numbered from 0 to 5, right to left.
Two power supplies (AC or DC) are accessed from the rear of the router and are hot-swappable.
The Cisco ASR 1001-HX Router can support two AC or two DC power supplies. Do not install mixed
AC and DC power supply units in the same chassis.
Caution
The following figure shows the rear of the Cisco ASR 1002-HX Router.

The chassis has a front-to-rear airflow. Four internal fans draw cooling air in through the front of the chassis
and across internal components to maintain an acceptable operating temperature. The fans are located at the
rear of the chassis. The fans are numbered from 0 to 3, right to left.
The power supplies used in Cisco ASR 1001-HX Router and Cisco ASR 1002-HX Router are different
and they should not be mixed or swapped. The size and structural dimensions are the same, therefore they
both look alike. It would be hazardous if you accidently inserted the wrong power supply into the PEM
slot.
