ATTO FibreBridge 3100R NVRAM Configuration Parameters Summar
y
This section provides information regarding updating the ATTO FibreBridge 3100R flash or
nvram parameters using updater.exe (MSDOS-based utility), SCSI Read Buffer or Write Buffer
commands. The buffer ID identifies the respective field for either updater input or via the
Read/Write Buffer commands. The nvram offset is provided to facilitate interpretation of nvram
contents directly. Accessing the ATTO FibreBridge 3100R via ATTO FibreBridge services
precludes the need to reference this summary. Unless otherwise indicated, items described herein
apply to all models of the ATTO FibreBridge. Items marked FB apply only to the ATTO
FibreBridge 2100R Product Module while items marked FBE apply only to the ATTO
FibreBridge 3100R model (2 GBIC connectors).
