If the left handle is damaged or positioned incorrectly the FortiGate-5001FA2 board does not receive power and will not start up. Make sure the left handle is correctly aligned, fully inserted and locked. Sometimes you may have to make small adjustments to the handle to achieve contact with the switch.
FortiGate-5020 chassis: incorrect FortiGate-5001FA2 jumper settings
If the JP3 jumper on the FortiGate-5001FA2 circuit board is set to detect a shelf manager, the FortiGate-5001FA2 board will not start up when inserted into a FortiGate-5020 chassis. This occurs because the FortiGate-5020 chassis does not have a shelf manager.
To fix the problem, remove the FortiGate-5001FA2 board and check the position of the JP3 jumper (see Figure 3 on page 12). Make sure the jumper connects pins 1 and 2 (to the right when seen from the front of the board).
FortiGate-5140 or 5050 chassis: shelf manager not installed or not functioning
If you are operating a FortiGate-5001FA2 in a FortiGate-5140 or 5050 chassis, the FortiGate-5001FA2 board will not start up if the JP3 jumper connects pins 2 and 3 (see Figure 3 on page 12) and a shelf manager is not installed or is not operating correctly.
If the shelf manager is not installed or not operating correctly, when you insert a FortiGate-5001FA2 board, the board attempts to communicate with the shelf manager. If the FortiGate-5001FA2 board cannot communicate with the shelf manager, the board will not startup.
If a shelf manager is installed, make sure it is functioning normally (the Status LED is green and all other LEDs are off). If the shelf manager is not functioning normally, you can try removing it from the chassis and reinstalling it. If this does not solve the problem, contact Fortinet Technical Support.
If the shelf manager has been removed from the chassis, you should re-install it. If you are planning on operating the chassis without a shelf manager, you can move the FortiGate-5001FA2 JP3 jumper between pins 1 and 2. The FortiGate-5001FA2 should now start up.
