HP ProLiant XL220a Gen8 v2-Server - Manual (Page 21)

Setup 21
CAUTION: To prevent improper cooling and thermal damage, do not operate the chassis unless
all bays are populated with a component or a blank.
To install the component:
1. Prepare the server for installation.
2. Install the server. When seated properly, the server will be flush with the front of the chassis and the
release lever will close completely without resistance.
Powering up the chassis
Connect the AC or DC power cables, depending on the power configuration.
When the circuit breakers are powered, the chassis and HP Advanced Power Manager have power. By
default, each installed component also powers up. Examine the HP Advanced Power Manager for any errors
which may prevent installed components from powering up.
