About DC power supplies
The BIG-IP
®
3900 platform supports hot swappable DC power supplies. 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.
The DC power supply includes a DC terminal block. Connect the wires from the DC power source to the terminal block
and then insert the terminal block into the DC power supply.

Caution: This product is sensitive to electrostatic discharge (ESD). We recommend that when you install or
maintain the unit, you use proper ESD grounding procedures and equipment.
Caution: Running without both power supplies installed in the platform can affect cooling and electromagnetic
interference (EMI). If you need to run the unit with only one power supply, you must install a blank supply bracket
into the other power supply slot. The blank supply bracket is required to maintain proper airflow in the system. If
you do not have a blank supply bracket, leave both supplies installed and unplug the unused power supply.
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.
Note: All copper grounding cable used for grounding must meet all appropriate UL standards.
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).
Note: The battery return terminals on the platform are in an isolated DC return (DC-I) configuration.
Note: The platform must be installed in a restricted access location such as a central office or customer premises
environment.
