​​Introduction to FGT_200D_POE-v6-build0528-FORTINET.out Software​​

This firmware package delivers FortiOS v6-build0528 for FortiGate 200D-POE series appliances, specifically optimized for Power-over-Ethernet (PoE) enabled network environments. As part of the FortiOS 6.4.x maintenance branch, it addresses 12 critical CVEs while enhancing performance for distributed office deployments and IP surveillance systems.

Designed for the FortiGate 200D-POE hardware platform, this release improves integrated 24-port PoE switch management and supports hardware-accelerated threat detection through CP8 ASIC chips. The firmware bridges security updates between FortiOS 6.4.5 and 6.4.9 versions, maintaining backward compatibility with existing SD-WAN configurations.
