Rack Warnings - HPE ProLiant DL360 User Manual

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.

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.
