Connecting Generation 2 Fortigate 6000F Psus To High Line Ac Power; Connecting Generation 1 Or 2 Fortigate 6000F Psus To Low Line Ac Power - Fortinet FortiGate 6000F Series System Manual

FortiGate 6000F series hardware description

Connecting generation 2 FortiGate 6000F PSUs to high line AC power

If you connect a generation 2 FortiGate 6000F to high-line AC power, each PSU provides 2000W AC, which is all the
power required by the FortiGate 6000F. Only two PSUs (PSU1 and PSU2) each connected to separate power feeds, are
required for full 1+1 power redundancy. PSU3 may also be connected if you have three separate power feeds and
provides 1+1+1 redundancy. To maintain redundancy, you should replace any failed PSUs.
See FortiGate 6000F series back panel on page 14
Recommended fully redundant configuration when connected to high-line AC power:
Two FortiGate 6000Fs in a High Availability (HA) configuration connected to two power feeds.
l
On both FortiGate 6000Fs, connect PSU1 and PSU2 to different power feeds.

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 series back panel on page 14
Recommended FortiGate 6000F low line AC power fully redundant configuration:
Two FortiGate 6000Fs (Unit 1 and Unit 2) in a High Availability (HA) configuration with two power feeds (Feed A and
l
Feed B).
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.
l
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.
FortiGate 6000F Series 7.0.12 System Guide
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.
