Issue
Significant changes and improvements were introduced with firmware revision 11.2P, including a streamlined "Flash clear" procedure.
For Ethernet NIMs with firmware revisions prior to 11.2P, the procedure was documented in Technical Bulletin 99-56 (see below).
The procedure in bulletin 99-56 was a revision of the procedure in the original NIM Networking and Configuration Practices manual, F-25955, which is no longer available. The current version of the manual, F-25955-4, applies only to NIMs with firmware revisions 11.2P and 11.2T.
Environment
Ethernet NIM for network 8000; GCM-ETH-001 with firmware revision prior to 11.2P.
Cause
"Flash clear" procedure was changed in firmware revision 11.2P
Resolution
Follow the "Flash clear" procedure per Technical Bulletin 99-56.
