Connecting generation 1 or 2 FortiGate-6000F PSUs to low line AC power
If you connect a generation 1 FortiGate-6000F or a generation 2 FortiGate-6000F PSU to low line AC power, each PSU
provides 1500W AC and at least two PSUs (PSU1 and PSU2) must be connected to power. PSU3 is a backup PSU and
provides 2+1 redundancy. All PSUs should be connected to AC power.
See
FortiGate-6000F back panel on page 13
for locations of the PSUs.
Recommended FortiGate-6000F low line AC power fully redundant configuration:
l
Two FortiGate-6000Fs (Unit 1 and Unit 2) in a High Availability (HA) configuration with two power feeds (Feed A
and Feed B).
l
Connect PSU1 and PSU2 of Unit 1 to Feed A. Connect PSU3 of Unit 1 to Feed B.
l
Connect PSU1 and PSU2 of Unit 2 to Feed B. Connect PSU3 of Unit 2 to Feed A.
For normal operation of a FortiGate-6000F connected to low line AC power, at least 2 PSUs must be operating and
connected to power. If two PSUs fail and only one PSU is operating, the FortiGate-6000F will continue to operate but
only four FPCs will be running, the remaining FPCs are shut down. This means the performance of the FortiGate-6000F
is reduced until at least two PSUs are connected.
If only one PSU is operating, the FortiGate-6000F shuts down the FPCs starting with the FPC
with the highest slot number, until only four FPCs are running. Usually this results in the FPCs
in slots 1 to 4 running if there is only one PSU connected.
If one of the FPCs in slot 1 to 4 has previously shut down, the FortiGate-6000F keeps the four
operational FPCs in the lowest slot numbers running. For example, if the FPC in slot 2 has
previously shut down, if only one PSU is operating, the FPCs in slots 1, 3, 4, and 5 continue
running.
The FortiGate-6000F also keeps the primary FPC running. Usually the FPC in slot 1 is the
primary FPC, so if only one PSU is operating, the FPCs in slots 1 to 4 continue running.
However, if the FPC in another slot has become the primary FPC, then this FPC as well as the
three remaining FPCs with the lowest slot numbers will continue running. For example, if the
FPC in slot 6 has become the primary FPC, then when only one PSU is operating, the FPCs in
slots 1, 2, 3, and 6 continue running.
AC PSU LED states
The PSU LED indicates whether the PSU is operating correctly and connected to power.
State
Description
Off
AC power not connected. If this LED is not lit, check to make sure the PSU is
connected to a power feed. If the power feed is good then the PSU has failed and
should be replaced.
Flashing green
The PSU is in standby mode, not supplying power to the chassis.
Green
Normal Operation with AC power connected.
Amber
Input voltage outside of normal operating range, PSU fan not operating, or output
voltage outside of normal operating range.
