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.

Procedure steps

Step Action

1 Remove the memory card from the Ethernet Routing Switch

8393SF/CPU or 8394SF/CPU module.

2 Locate the read-write protect switch on the edge opposite the

arrow on the memory card.

3 Adjust the read-write protect switch.
