Connecting the RMX 4000 to Power Sources
You can connect either an AC Inlet or to DC power according to the
power system required at your site:
•
For systems with AC Power, up to three power supplies can be
installed with one being redundant (n+1).
• For systems with DC Power, up to two power supplies can be
installed with one being redundant (n+1), and each power supply has
a built in circuit breaker. With DC power, slot 10 (the center slot)
must remain unoccupied.
Follow the steps appropriate specified below for your power system.
The following restrictions apply to the conductors and connectors that
may be used to ground the unit when rack mounted:
•
When using bare conductors, they must be coated with an
appropriate antioxidant compound before crimp connections are
made. Tinned, solder-plated or silver-plated connectors do not have
to be prepared in this manner.
• The same bolt assemblies should not secure multiple connectors.
