Upgrading Routers from Version 7-11.xx to Version 12.00
E-4 117404-A Rev. A
Using Flash Cards from Previous Releases
All Bay Networks routers running Router Software Version 7.60 to 8.10, and
AFNs running Router Software Version 7.5x, write to flash cards using a 68-space
file format. Bay Networks BNs (BLN, BLN-2, and BCN) running Router
Software Version 7.5x write to flash cards using a 61-space file format.
T
able E-2 shows which Bay Networks routers can read, write, and boot from the
different file format types.
When a BN running Router Software Version 8.10 or 9.00 reads a flash card that
contains files written by a BN running Router Software Version 7.5x, and you
enter the
dinfo command at the Technician Interface prompt, the display indicates
that the volume is corrupted. If you request a directory of the volume’s contents
(using the
dir command), the display indicates that the contiguous free space is 0
(zero). You can, however, read and boot from the files.
