■ Cleaning the Server Interior
In dusty environments, dust deposits in the server. Dust deposits may cause a server failure, fire, or
electric shock. To keep the PRIMERGY server in good condition, use a vacuum cleaner periodically to
remove dust deposits.
Cleaning components
CPUs: Dust deposits must be removed because it will impair the cooling performance.
Fans: Remove dust from and around the fans.
Memory/expansion cards: Remove dust between memory modules and between expansion cards.
Remove dust from the connector before adding a memory module or an expansion card.
Internal hard disk units/5-inch internal devices: Remove dust deposits from units and devices. Tape
devices are particularly susceptible to dust and may cause failures. Install them in a clean
environment.
Be careful when removing components such as CPUs, memory modules, or hard disk units. Be sure to
install parts and cables in the original position.
Leaving dust brushed off or blown with air in the server can cause failure. Be sure to take it out of the
server.
