WARNING: When installing a DC power supply, the ground wire must be connected before the positive or negative
leads.
WARNING: Remove power from the power supply before performing any installation steps or maintenance on the
power supply.
CAUTION: The server equipment connects the earthed conductor of the DC supply circuit to the earthing
conductor at the equipment. For more information, see the documentation that ships with the power supply.
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.
RCM module option
The RCM module allows daisy chaining of multiple chassis for iLO aggregation at the chassis level. The RCM module can
be connected to a ToR management switch or to the HPE Apollo Platform Manager for a rack-level power and system
management.
