7 Make sure the power wires are secured to the chassis using the power wire fixture and
tie wraps if required.
8 If required, label the black wires -48V.
9 If required, label the red wires RTN.
10 Re-attach the protection plate to the FortiGate-5050 power input connector.
11 Attach the clear plastic cover to the back of the FortiGate-5053 power converter tray.
12 Connect the FortiGate-5053 power converter tray to AC power.
Only connect the power supplies that are installed in the FortiGate-5053 to AC power.
For example, if your FortiGate-5053 includes two FortiGate-5020/5050 power supplies,
the power supplies will be installed in slots 1 and 2. In this case you should only
connect AC in connectors 1 and 2 to AC power. If your FortiGate-5053 power converter
tray contains three power supples, connect all three AC in connectors to AC power.
The photograph in Figure 15 shows the back panel of a FortiGate-5053 wired to provide
power to a FortiGate-5050 chassis. This photograph also shows the clear back cover of
the FortiGate-5053 installed. You should install this cover using the mounting hardware
provided. Install the cover after connecting the power but before turning the power on.
