Statement 1005
Cisco ASR 1004 AC Power Supply
This section provides information about the AC power supplies on the rear of the Cisco ASR 1004
Router. The power supply module contains three fans. A total of six fans are used to cool the ASR 1004
system and power supply. The airflow direction is front to back.
Power supply modules with internal fan modules install into the rear of the chassis. These modules
contain handles to ease installation and removal. The AC power supply has a front panel mounted switch
that powers on and off the power supply. This switch will not disconnect the AC line, but will act only
as a standby switch to the power supply. The front panel includes a mechanical guard to prevent the
standby switch from being tripped due to accidental contact.
Guide pins located at the rear of these modules help center locate the modules and reduce stress to the
midplane and module mounted connectors. Four captive screws (tool operated latches) are provided on
the modules face plate (chassis rear) to secure these modules into the chassis.
