About DC power supplies
The BIG-IP
®
8950 platform supports DC power supplies, which are hot swappable if at least two power
supplies are 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.
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: Running without power supplies installed in all available bays in the platform can affect
cooling and electromagnetic interference (EMI). If you need to run the unit with fewer power supplies,
you must install a blank supply bracket into any empty power supply bays. The blank supply bracket
is required to maintain proper airflow in the system. If you do not have a blank supply bracket, leave
all supplies installed and unplug any unused power supplies.
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 Networks recommends that
you use proper ESD grounding procedures and equipment when you install or maintain the unit.
