Cyclades-TS Installation Manual
After printing “Linux/PPC load: root=/dev/ram”, the Cyclades-TS waits approximately 10 seconds for user input.
This is where the user should type “single”. When the boot process is complete, the Linux prompt will appear
on the console:
[root@(none) /]#
If the password or username was forgotten, execute the following commands:
passwd
saveconf
reboot
For configuration problems, the user has two options:
1.Edit the file(s) causing the problem with vi, then execute the commands
saveconf
reboot
2.Reset the configuration by executing the commands:
echo 0 > /proc/flash/script
reboot
If the problem is due to an upgrade/downgrade, a second downgrade/upgrade will be necessary to reverse the
process. First, the network must be initialized in order to reach a ftp server. Execute the following script,
replacing the parameters with values appropriate for your system. If your ftp server is on the same network as
the TS, the gw and mask parameters are optional.
config_eth0 ip 200.200.200.1 mask 255.255.255.0 gw 200.200.200.5
At this point, the DNS configuration (in the file /etc/resolv.conf) should be checked. Then, download the kernel
image using the ftp command.
