Software Release 2.6.1
C613-02039-00 REV A
What to Do if You Clear FLASH Memory Completely
DO NOT clear the FLASH memory completely. The software release files are
stored in FLASH, and clearing it would leave no software to run the switch.
If you accidentally do this, you will need to:
1. Boot with default configuration.
Reboot the switch from a terminal connected the asynchronous terminal
port (not Telnet). Use the install override to run the default configuration
(see “How the Switch Starts Up” on page 108).
2. Log in.
Log in to the switch using the default password friend for the manager
account.
3. Put current software release on server.
Make sure you have the current software release and patch files on a server
connected to the switch by the switch port or Ethernet port. Current
software release and patch files are downloaded from the support site at
http://www.alliedtelesyn.co.nz/support/ar400.
4. Assign an IP address.
Assign an IP address to the switch interface over which the software files
are downloaded (see “Assigning an IP Address” on page 15).
5. Load software files onto switch.
Load the required software and patch onto the switch (see “Loading and
Uploading Files” on page 52).
6. Set the install information.
Set the switch to use the software installed (see “Upgrading Switch Software”
on page 56).
7. Reco nfigure the switch.
If you have a copy of the recent configuration file stored on your network,
you can download this onto the switch too. Otherwise you will need to re-
enter all configuration.
While FLASH is compacting, do not restart the switch or use any commands
that affect the FLASH file subsystem. Do not restart the switch, or create, edit,
load, rename or delete any files until a message confirms that FLASH file
compaction is completed. Interrupting flash compaction may result in damage
to files. Damaged files are likely to prevent the switch from operating correctly.
If you accidentally restart the switch, or use any commands that affect the
FLASH file subsystem, contact your authorised distributor or reseller. You may
have to return the switch to the factory.
