ATTO FibreBridge 3100R NVRAM Configuration Parameters Summary

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).
