Connecting the DC power supply
After the 6900/8900 platform is installed in a rack, you have assembled and
wired the wiring block, and you have installed the DC power supply into the
platform, you can connect the platform to the DC power source.
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.
Important
When you connect the DC power source, F5 Networks recommends that you
follow the safety requirements defined for the facilities where the
DC-powered platforms will be installed.
To connect DC power source to the platform
1. Make sure that the power from the DC power source is off.
2. Ensure that the wiring block is not connected to the power supply
before adding it to the unit.
3. Remove the existing AC or DC power supply, if one is installed. For
information on removing a power supply, see Replacing a power
supply , on page 8-6.
4. Loosen the power supply screw, using an appropriate screwdriver if
necessary.
