When the Webserver has been disabled

Problem:

The web server was previously switched off, and now it is necessary to check the monitoring screens and update its configuration. The CS141 is running but is not accessible. This tutorial explains how to reset your CS141 and start over, as the device is not completely locked up.

Use Backups

“Disable the web server” is restrictive, so it takes a little bit of planning before you set the web server restrictively to "OFF": As soon as the web server has been disabled, it will be a little awkward to add some configuration on the CS141 – the current configuration interface is gone. But if you have a backup file you may be able to recover nearly the complete configuration of your device. Which final backup / restore strategy you choose depends on what you want to achieve.
In principle, there are two basic scenarios:

1. You need to change configuration regularly
   Make the full data backup before you disable the web server. You can easily create the backup via the System > Backup Configuration.

2. Change a single device that runs “as configured” by a new one
   Create a backup file after disabling the web server. Since the configuration interface is offline, you cannot press System > Backup to create it. So just enter:

http(s)://<your IP address>/backup
 

You will be asked for the standard user name admin and the current password (Standard: cs141-snmp).

Note:
In both cases, the rule is that a backup should only be used with a device that comes with the same or a newer firmware version. An older firmware may not work as expected because changes during a firmware update may change the format of the backup file, add features or something like that. The older firmware version may not know how to handle these changes.

Using a Backup file

After you have switched off the web server, you can no longer change the configuration. If you do not have a backup now, you will have to completely reconfigure the CS141 after resetting the configuration.

Otherwise, it works as followed:

1. Reset the CS141:

At your web browser, enter this command:

               http(s)://<you IP address>/update
Even the web server is already disabled, some functions will still work. One of these functions is the direct call of the update window:

Marking „Reset to factory default will advise the CS141:

• Delete the basic device configuration

• Keep the network settings

After flashing, the CS141 will restart and the web interface is available. Open System>Backup and use drag and drop to place the backup file.

2. Change the device 1:1 by another device / spare part

Open the flash routine as described, and then insert the backup file. Since you have a backup file with a disable web server, the backup will lock up the user interface! You cannot change settings. The new device will run as configured like your old device. Ensure to use all backup file items.

If you want to refresh a broken configuration file, just use the complete backup file.

If you want to change the device by a spare part, please note, that you need to depower the original device before powering up the spare part. Otherwise, you may get an IP address conflict.
