General Installation Precautions
• Use a regulating uninterruptable power supply (UPS) to protect the
RMX 4000 from power surges and voltage spikes, to keep your MCU
operating in case of a power failure. The RMX 4000 requires either
two (DC) or three (AC) power supply cables, each connected to a
power supply.
• Allow the power supply units to cool before touching them.
• When handling electronic components, standard anti-static
precautions must be observed:
—
Wear a grounding strap
— Handle cards by their edges only and do not touch their
components or connector pins
— Keep components in anti-static bags, when not installed in the
RMX 4000
Rack Mount Safety Precautions
The following precautions should be followed when installing the
RMX 4000 on a rack:
•
The RMX 4000 has a height of 6U. Ensure this space is available on
the rack.
• Ensure that the leveling jacks on the bottom of the rack are fully
extended to the floor with the full weight of the rack resting on them.
• In a single rack installation, stabilizers should be attached to the rack.
• In multiple rack installations, the racks should be coupled together.
• Always make sure the rack is stable before extending a component
from the rack.
• You should extend only one component at a time - extending two or
more simultaneously may cause the rack to become unstable.
• Before you install the rails, determine the placement of each
component in the rack.
• Install the heaviest components on the bottom of the rack first, and
then work up.
Attention:
The RMX 4000 can weigh up to 40kg when all slots are occupied. Two people
are required to lift the MCU out of the box and also when installing it in a rack.
