Figure 13: The 650W DC power supply
Caution: Before installing a DC power supply unit, be sure that the circuit breaker for the DC mains
power to the power supply unit is switched off.
Caution: Before you begin to work with one of these platforms, refer to the DC-powered equipment
environmental warnings for this platform and review any safety requirements for the facilities where the
DC-powered platforms will be installed.
Important: You should use only one power supply unit type (AC or DC) in a platform. AC and DC
interoperability is not supported.
Important: The platform must be installed in a RESTRICTED ACCESS LOCATION, such as a central
office or customer premises environment.
Note: Copper cables used for grounding must meet appropriate safety standards.
Note: Bare conductors should be coated with an appropriate antioxidant before being crimped. Make
sure to clean all unplated connectors, braided strap, and bus bars to a bright finish prior to coating them
with the antioxidant.
Note: The platform must be grounded to a common bonding network (CBN).
Note: The battery return terminals on the platform are in an isolated DC return (DC-I) configuration.
Note: When you are running a redundant DC power supply configuration, F5
®
strongly recommends that
each DC power supply unit in the system receives power from independent DC main power sources with
independent circuit breakers.
Note: After removing input power from any power supply unit, wait 30 seconds before reapplying input
power to the power supply unit.
