Safety inspection checklist
Use the information in this section to identify potentially unsafe conditions with your server. As each machine was designed and built, required safety items were installed to protect users and service technicians from injury.
If your working condition necessitates the server being powered off or you intend to power off, make sure that the power cord is disconnected.S002CAUTIONThe power-control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device.
