Warnings and cautions
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 may 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.
WARNING: When installing a server in a telco rack, be sure that the rack frame is
adequately secured to the top and bottom of the building structure.
WARNING: This server is very heavy. To reduce the risk of personal injury or damage to
the equipment:
• Observe local occupational health and safety requirements and guidelines for manual
material handling.
• Get help to lift and stabilize the product during installation or removal, especially
when the product is not fastened to the rails. When the server weighs more than 22.5
kg (50 lb), at least two people must lift the server into the rack together. A third
person may be required to help align the server if the server is installed higher than
chest level.
• Use caution when installing the server in or removing the server from the rack; it is
unstable when not fastened to the rails.
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 power is removed.
CAUTION: Protect the server from power fluctuations and temporary interruptions with a regulating
uninterruptible power supply (UPS). 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.
