FPR9300 and FPR4100 Series Security Appliances – Some Appliances Might Fail to Pass Traffic After 3.2 Years of Uptime
Due to a flaw in solid-state drive (SSD) firmware, the SSD that is internal to the FPR9300 Supervisor module and FPR4100 Series security appliances will no longer respond after approximately 3.2 years of cumulative operation. After the first unresponsive event occurs, every subsequent power-cycle allows the SSD to operate for approximately six weeks of cumulative operation before the SSD will no longer respond again.
