## How to Apply Standby Power for Initial Service Processor Configuration

Use this procedure to apply standby power to the SP before initial configuration.

| Caution - Possible equipment damage. Do not operate the server without all fans, component heatsinks, air baffles, and the cover installed. Severe damage to server components can occur if operated without adequate cooling mechanisms.

| Caution - A maximum of two power cords can be connected to a single branch circuit. The remaining power cord(s) must be connected to a second branch circuit.

- Ensure that grounded AC power cords are plugged into the four AC power connectors on the back panel of the server and into grounded AC power outlets on two separate branch circuits (see Caution above).

  When power is connected, the server boots into standby power mode. After the SP boots and is ready to use, the Power/OK LED on the front panel flashes to indicate standby power mode. For the LED location, see Sun Fire X4640 Server Front Panel Features and Components.

  Note - Do not apply main power to the rest of the server until you are ready to install or configure a platform operating system. At this point, standby power is supplied only to the Graphics Redirect and Service Processor (GRASP or SP for short) board and power supply fans.
