About DC power supplies
The platform supports power redundancy, which ensures that the system is unaffected if a single power
supply fails in a system with a working redundant supply. For redundant operation, there must be two or
more working power supplies if 1-3 blades are installed, and there must be three or more working power
supplies if 4-8 blades are installed. For maintenance, you can replace a working power supply, provided
that there are working redundant supplies installed in the system.
The DC power supply does not have an on/off switch. You can control the power from the rack switch or
the DC power source.

Caution: Running without all power supplies installed in the platform can affect cooling and electromagnetic
interference (EMI). If a power supply fails, you can leave it installed in the chassis and remove the power
cord; the system, however, will continue to log errors. If you need to run the unit without all power supplies
installed, you must install a blank supply bracket into any empty power supply slots. The blank supply
bracket is required to maintain proper airflow in the system.
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: This product is sensitive to electrostatic discharge (ESD). F5
®
recommends that you use proper
ESD grounding procedures and equipment when you install or maintain the unit.
Important: The platform must be installed in a RESTRICTED ACCESS LOCATION, such as a central
office or customer premises environment.
Note: All copper grounding cable must meet all appropriate safety standards and local electric codes.
Note: You should coat bare conductors with an appropriate antioxidant compound before you make crimp
connections. You should bring all unplated connectors, braided strap, and bus bars to a bright finish and
then coat them with an antioxidant before you connect them.
Note: The platform must be grounded to a common bonding network (CBN).
