Cisco ASR 1001, Hardware Installation Manual

Page: 597 / 702

If you remove a power supply from a system that has four power supplies that are connected and powered
on, the system can run only for a maximum of five minutes before shutting down. However, because the fans
and power elements are independent within the power supply, the replacement power supply does not have
to be energized within five minutes. The only requirement is that the power supply be installed in the chassis
in order to energize the fans and maintain proper system cooling.
Caution
Step 8 Grasping the power supply handles, pull the power supply from the chassis.

The color coding of the DC input power supply leads depends on the color coding of the DC power source
at your site. Typically, green or green/yellow is used for ground (GND), black is used for negative (

)
terminal and red is used for the positive (+) terminal. Make certain the lead color coding you choose for
the DC input power supply matches lead color coding used at the DC power source.
Note
When you install the unit, the ground connection must always be made first and disconnected last. Statement
