Installing ServerIron ADX
2
CAUTION
To insure adequate bonding when attaching the ground lug, a minimum of 20 PSI of torque is
required to be applied to the mounting hardware used to attach the ground lug.
CAUTION
For the NEBS compliant installation of a ServerIron ADX device with AC and DC system use a
ground wire of at least 6 American Wire Gauge (AWG). The ground wire should have an
agency-approved crimped connector (provided with the chassis) attached to one end, with the
other end attached to building ground. The connector must be crimped with the proper tool,
allowing it to be connected to both ground screws on the enclosure. Before crimping the ground
wire into the provided ground lug, (Panduit LCD6-10AF-L), insure the bare copper wire has been
cleaned and antioxidant is applied to the bare wire.(ADX-1000 only)
CAUTION
When making the primary ground connection, a star washer must be used for anti-rotation. When
connecting the device to the rack frame, use thread-forming screws and paint-piercing washers.
CAUTION
AC and DC power supplies can be grounded to a common bonding network or to an isolated
bonding network.
Connecting DC power to a chassis
You can use a DC power source for the chassis. This is supported through use of a DC-to-DC power
supply. DC power must be supplied at -48 V and 30 A. The DC-to-DC supply provides the DC power
to the chassis at 12 V and 100 A.
DANGER
DC return shall be isolated from the chassis ground (DC-I) when connections to the power supply
are made.
DANGER
The procedure in this section is for qualified service personnel.
