This article contains information regarding "1394a PCIe 1.0 (Firewire) card causes reboot on shutdown or enter a reboot loop when installed in OptiPlex 3020".
Some OptiPlex 3020 system users have reported issues on shutdown after installation of a 1x PCIe 1.0 1394a (Firewire) network card in the system. Systems included rebooting of the system when shutdown selected or the system entering a reboot loop requiring the system to be hard powered off by pressing and holding the POWER button till the power supply turns off. When the card is removed, the issue no longer occurred.
Flashing the BIOS to the most current version had no effect.
A workaround was discovered for this issue.
Entering the Basic Input/Output System (BIOS) and changing the Wake on LAN (WOL) setting from the default Disabled to Enabled allowed the system to operate normally.
