Mediant 9000 SBC
Caution:
This equipment is designed to permit the connection of the earthed conductor of the DC
supply circuit to the earthing conductor at the equipment. If this connection is made, all
of the following 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 must 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 must be earthed elsewhere.
•
The DC supply source is to be located within the same premises as the equipment.
•
Switching or disconnecting devices must not be in the earthed circuit conductor
between the DC source and the point of connection of the earthing electrode
conductor.
Caution:
To reduce the risk of electric shock or energy hazards:
•
This equipment must be installed by trained service personnel, as defined by the
NEC and IEC 60950-1, Second Edition, the standard for Safety of Information
Technology Equipment.
•
Connect the equipment to a reliably grounded SELV source. An SELV source is a
secondary circuit that is designed so normal and single fault conditions do not cause
the voltages to exceed a safe level (60 V DC).
•
The branch circuit overcurrent protection must be rated 24 A.
Caution:
•
When installing a DC power supply, the ground wire must be connected before the
positive or negative leads.
•
Remove power from the power supply before performing any installation steps or
maintenance on the power supply.
Notes:
•
The DC power cord is not supplied.
•
If you are not using an HP input cable, use an HP-approved 10 or 12 AWG green
and yellow ground cable, no shorter than 150 cm (59.06 in), and 10 or 12 AWG
power cables.
To connect the device to the DC power supply:
1.
Make sure that the power supply module is partially extracted from the chassis slot.
This facilitates cable attachment described hereafter.
2.
Remove the blank cover protecting the DC power inlet on the rear panel.
