		d. The power-on LED on the blade server control panel is blinking slowly.
		v If the power LED is blinking rapidly and continues to do so, the blade
		server is not communicating with the management module; reseat the
		blade server, then go to step 3
		v If the power LED is off, the blade bay is not receiving power, the blade
		server is defective, or the LED information panel is loose or defective.
		e. Local power control for the blade server is enabled (use the BladeCenter
		management module Web interface to verify), or the blade server was
		instructed through the management module (Web interface or IBM Director)
		to turn on.
	2. If you just installed an option in the blade server, remove it, and restart the
		blade server. If the blade server= now turns on, you might have installed more
		options than the power to that blade bay supports.
	3. Try another blade server in the blade bay; if it works, replace the faulty blade
		server.
