Maintenance, cleaning and handling of internal devices

Unplug AC Cables before maintenance.

Before maintenance, power off all devices installed on the Blade Enclosure and unplug AC

Cables. Even if devices are powered off, there is a risk of electric shock or fire as well as

malfunction when maintenance is performed for the devices on the Blade Enclosure with

their AC Cables plugged.

Disconnect the power plugs from the power outlet occasionally and clean the plugs with a

dry cloth. Heat will generate if condensation is formed on a dusty plug, and may lead to a

fire.
