Connecting the FortiGate-5140 chassis to AC power using the FortiGate-5053 power converter tray
Redundant FortiGate-5053 power converter trays
24
A single FortiGate-5053 power converter tray is usually only connected to one
FortiGate-5140 PEM. If this PEM or FortiGate-5053 power converter tray fails or is
disconnected the FortiGate-5140 chassis will lose power.
You can supply redundant power to the entire FortiGate-5140 chassis by adding a second
FortiGate-5053 power converter containing two or three FortiGate-5140 power supplies
and connected this FortiGate-5053 power converter tray to the second FortiGate-5140
PEM.
