Server Warnings And Caution - HP Apollo 4200 Gen9 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.

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.
