Figure 16: An example of an AC power supply
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: The power socket outlet should be installed near the equipment and easily accessible.
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.
Note: Depending on the model and revision type of the power supply, you might need either a Phillips or
a slotted screwdriver to replace the power supply.
Installing an AC power supply
If a power supply is already installed in the bay where you are installing the replacement supply, disconnect
the AC power cord for the corresponding power supply from the back of the chassis and remove the existing
supply from the chassis.
You can add or replace an AC power supply as part of routine maintenance or in the event of a power supply
failure. You do not need special tools to replace the power supply.
1. Remove the bottom bezel from the chassis by pulling straight out using the indentations on both sides.
