Protecting Files on the Flash Memory Card

Bay Networks ships each memory card with its read/write protect switch in the unprotected position. Bay Networks recommends making a copy of your conﬁguration ﬁles on another ﬂash memory card, write-protecting the card, and storing it in a safe place for backup purposes.

NOTE:

You typically do not operate a router with a write-protected memory card. You may need to permanently store online network changes and software upgrades, or to restore network operation by downloading changes.

1. Remove the memory card, as described on page 5.
