2. Connect the server power cords to the power supply AC connectors on the back
panel of the server and use a Velcro strap to secure them to the power supply
handle as shown in the figure below.
When the power cords are connected, the power supply LEDs light and the SP OK
LED will blink rapidly as the service processor (SP) boots. After the SP has booted,
the Power/OK LED on the front panel will blink slowly, indicating the host is in
standby power mode. In standby power mode, the server is not yet initialized or
powered on.
Caution – Do not operate the server unless all fans, component heatsinks, air
baffles, and the top cover are installed. Damage to server components can occur if the
server is operated without adequate cooling mechanisms.
Note – Do not apply main power to the rest of the server until you are ready to
configure a preinstalled operating system or perform a fresh install of an operating
system. At this point, power is supplied only to the SP and the power supply fans.
