Turning On the Chassis Power

Although you can install or replace modules in an operating chassis, in a new installation you may prefer to install all the modules before turning on the chassis power.

To turn on the chassis power:

1.Verify that all power cords are connected properly, as described in the installation instructions for the power supplies.

2.Turn all the power switches to the On position.

Note: In a chassis with two power supplies in a nonredundant power configuration, you must turn on both power supply units within 2 seconds of each other. If you wait longer to turn on the second power supply, both power supplies will shut down. To correct this condition, turn off both power supplies, wait at least 30 seconds, and then turn on both power supplies again within 2 seconds.
