Protecting memory card files
Write-protect the memory card for backup purposes after you successfully load the configuration file and save your configuration because Nortel ships each memory card with the read-write protect switch in the unprotected position.
Typically, you do not operate the switch with a write-protected memory card. Make a copy of your configuration on another memory card, write-protect that card, and store it in a safe place. If you do not have a second memory card, you can copy your configuration to a File Transfer Protocol (FTP) or Trivial FTP (TFTP) server.
Prerequisites
•Remove the card from the Ethernet Routing Switch 8393SF/CPU or 8394SF/CPU module before changing the read-write protection.
ATTENTION
You must remove the card from the Ethernet Routing Switch 8393SF/CPU or 8394SF/CPU module before changing the read-write protection. Failure to remove the card can result in improper write protection.
