WARNING:
To reduce the risk of personal injury from hot surfaces, allow the drives and the internal system
components to cool before touching them.
WARNING:
To reduce the risk of personal injury, electric shock, or damage to the equipment, remove the power
cord to remove power from the server. The front panel Power On/Standby button does not completely
shut off system power. Portions of the power supply and some internal circuitry remain active until
AC/DC power is removed.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating uninterruptible
power supply. This device protects the hardware from damage caused by power surges and voltage
spikes and keeps the system in operation during a power failure.
CAUTION:
Do not operate the server for long periods with the access panel open or removed. Operating the server
in this manner results in improper airflow and improper cooling that can lead to thermal damage.
Rack warnings
WARNING:
To reduce the risk of personal injury or damage to the equipment, be sure that:
• The leveling jacks are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.
WARNING:
To reduce the risk of personal injury or equipment damage when unloading a rack:
• At least two people are needed to safely unload the rack from the pallet. An empty 42U rack can
weigh as much as 115 kg (253 lb), can stand more than 2.1 m (7 ft) tall, and might become unstable
when being moved on its casters.
• Never stand in front of the rack when it is rolling down the ramp from the pallet. Always handle the
rack from both sides.
Electrostatic discharge
Be aware of the precautions you must follow when setting up the system or handling components. A
discharge of static electricity from a finger or other conductor may damage system boards or other static-
sensitive devices. This type of damage may reduce the life expectancy of the system or component.
To prevent electrostatic damage:
• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
