Setup 42
CAUTION: If the DC connection exists between the earthed conductor of the DC supply circuit
and the earthing conductor at the server equipment, the following conditions must be met:
• This equipment must be connected directly to the DC supply system earthing electrode
conductor or to a bonding jumper from an earthing terminal bar or bus to which the DC
supply system earthing electrode conductor is connected.
• This equipment should be located in the same immediate area (such as adjacent cabinets)
as any other equipment that has a connection between the earthed conductor of the same
DC supply circuit and the earthing conductor, and also the point of earthing of the DC
system. The DC system should be earthed elsewhere.
• The DC supply source is to be located within the same premises as the equipment.
• Switching or disconnecting devices should not be in the earthed circuit conductor between
the DC source and the point of connection of the earthing electrode conductor.
To connect a DC power cable to a DC power source:
1.
Cut the DC power cord ends no shorter than 150 cm (59.06 in).
2.
If the power source requires ring tongues, use a crimping tool to install the ring tongues on the power
cord wires.
IMPORTANT:
The ring terminals must be UL approved and accommodate 12 gauge wires.
IMPORTANT: The minimum nominal thread diameter of a pillar or stud type terminal must be
3.5 mm (0.138 in); the diameter of a screw type terminal must be 4.0 mm (0.157 in).
3.
Stack each same-colored pair of wires and then attach them to the same power source. The power
cord consists of three wires (black, red, and green).
For more information, see the documentation that ships with the power supply.
Server warnings and caution
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
handling.
• Reduce the weight of the server by removing the drives and power input modules before
installing or removing the server from the rack.
• Obtain adequate assistance to lift and stabilize the server during installation or removal.
Hewlett Packard Enterprise recommends that a minimum of two people are required for
installing or removing the server from the rack. A third person might be required to help
align the server if the server is installed higher than chest level.
• Use caution when installing 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, power
input modules, 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.
