Affected Product(s):
F5OS Velos
Known Affected Versions:
F5OS-C 1.8.2
Opened: Dec 23, 2025 Severity: 3-Major
Shortly after a VELOS BX520 blade boots up, the health status of the blade shows an error for one of the FPGAs, it never clears, and the blade still successfully runs traffic. There are also verification errors in velos.log. For example, in confd: "blade/firmware/fpga/atse1 firmware:update-status unhealthy error error" In velos.log, entries such as: "FWU response error." ... "PCI slot ca:00.0 width is 4; expected 8." FWU atse2 Verification failed, retrying (also appears in the blade PEL) FWU atse2 Verification failed (also appears in the blade PEL)
One or more of the FPGA-to-CPU (PCIe) links may be running in a degraded state and could affect the bandwidth of traffic between the blade's FPGA and CPU.
Booting up a VELOS BX520 blade.
The blade can be rebooted to retry the FPGA load process, which will retrain all the FPGA PCIe links.
