Power Up and Power Down a Chassis with Modular Configuration Power
This section describes how to power up and power down a chassis with a modular configuration AC or DC
power shelf. For details on the chassis power systems, see
and
DC Power
Most components on the chassis, such as the PMs, alarm modules, and fan trays, can be removed or installed
in the chassis while it is running. Although it is possible to install or remove a power shelf while the chassis
is running, it is recommended to remove power from the chassis completely, if possible, for service protection
and safety.
