Most common problems while configuration and updating

For this configuration step, navigate to the following menus:

Data backup offers the option of completely backing up the current system configuration in order to quickly perform a recovery if required. The backup and restore will be done in two steps:

Step 1: Perform a backup

Open Backup. Under Save Configuration, click Backup to locally save a backup file to your download directory. Since the backup function is system-critical, CS141 asks for the valid administrator password.

This data backup can be run with any CS141 using a similar or higher OEM firmware version. Please note, renaming the backup file is subject to some restrictions that may a lead into an invalid restore procedure:

backup-200001707T0416.tar.gz

To change the name of the backup file, please follow these guidelines:

• Use the packed file exactly as downloaded.

• The section marked in red cannot be changed.

• Do not use spaces in the file name.

• Do not use special characters.

Step 2: Restoring data

Importing a backup uses the same menu as exporting.

1. Use drag-and-drop to place the packed file into the box, or left-click the box to open a file browser and select the desired backup file.

2. Click Restore to start the recovery process.

3. During the recovery process, the CS141 unpacks the file and applies it as the current configuration.

4. After the process is complete, you will automatically be logged out and must log in again using the credentials stored in the backup.

Restoring network data

If you back up multiple identically configured CS141 Web Managers, you can choose to exclude IP address settings from the recovery. By doing so, the previously configured IP address will remain unchanged while all other configurations are restored.

Note:
Backups from a CS141 are compatible with any CS141 running the same or a later firmware version. If a backup is used on a device with an older firmware version, issues may occur. This is caused by general improvements and the addition of new features that are not supported by older firmware. In some cases, the backup may not work at all.

Firmware updates

Firmware updates can be found at Generex.de in the download area. These System updates are regularly provided for the CS141. In addition to general product enhancements such as increased stability and improvements in operation and reliability, these updates also regularly provide new features that integrate seamlessly to existing configurations.

By default, the OEM ID 12 / GENEREX is preinstalled on delivery.

Deviations will result if you have purchased the Web Manager as part of a UPS from a manufacturer that comes with OEM agreements.

Note:
Due to the fact the CS141 is not technically locked, you can install the OEM version of another manufacturer at any time. In case another UPS is used, just install a corresponding OEM firmware version.

Under Firmware, select the version you need to use and download it to your computer. Unpacking the file is not necessary.

Note:

Make sure you download the right HW Revision.

You can find out the hardware revision of your device via its web interface. Go to the "System > About" page to view the details of your device. There, under the "Hardware" section, the item "Features" is listed, indicating which hardware revision your device has: Either "hw141" or "hw161" - if it says "bch8" or "bch16" then it's "hw141".

After downloading, open the web interface of the CS141 and open Update:

Drag the downloaded, packed file directly to the provided window. Clicking Start will trigger the update process. Before triggering the update with the Start button, you can select the following additional options:

Reset to factory settings
This option deletes all configurations during the update and returns the device to the delivery state.

Reset the network to factory settings
This option also resets the network and IP settings to factory defaults.

Note:
These two options are independent of each other to ensure not losing the IP settings. Due to this fact, a factory reset using remote access to the CS141 is possible. Please note Reset network to factory settings needs to be de-selected if CS141 has to hold its IP settings.

Since the update is interactive, please remain on the page until you are prompted to restart the device. Under System, open the About menu to check the success of the update.

Flash Procedure for Old Firmware Versions

Regardless of whether the device is running in Normal Mode or Rescue Mode, firmware version 1.90 is the prerequisite for updates. If you are using an older firmware, you must first install version 1.90.

Procedure (when Rescue Mode is active with old firmware):

1. Update to firmware version 1.90.

2. After the restart, remove the rescue jumper and restart the device again (hardware setting).

3. Update to the current firmware.

4. After reboot and initial configuration, repeat the flash procedure without selecting “Factory Reset” to update Rescue Mode to the latest firmware version.

Changing OEM Firmware

The CS141 Web Manager comes in two different firmware versions:

• GENEREX - ID 12

• OEM version of the manufacturer of your UPS

If you cannot find your UPS in the list of selectable UPS units, it may be necessary to install a different firmware.

For this, it is necessary to understand how you can detect the currently installed firmware and the required firmware:

The current firmware
You can see the current firmware by the logo in the top left corner:

Depending on the manufacturer, you will find the corresponding logo.

Checking firmware version

In the general system information, you will find this entry

CS141-SNMP V1.64.12 171213

The firmware version shows the OEM key:

V1.64      - the current firmware

.12           - the currently installed OEM version

171213    - DD/MM/YY reads the creation date backwards

If you want to operate the CS141 in a UPS of another manufacturer, you will find the necessary firmware on www.generex.de in the download area

Use Show Version Info to check if updated firmware is available for download. Please note that unlike updating within the same OEM firmware, changing the OEM firmware requires triggering a factory reset since features and functions may vary among UPS manufacturers.

Most common problems while configuration and updating

Dip-switches / Slide Switch in Wrong Position

If the slide switch is set incorrectly, the CS141 may use either the configuration mode IP address or an address assigned via DHCP. In such cases, the CS141 may no longer be reachable.
Since configuration mode uses the hardcoded IP address 10.10.10.10, this may also cause a network error if multiple CS141 devices are connected, as they all share this default address.

Forgotten Manual IP Address Assignment / Factory Default IP

If manual IP settings were forgotten or reset to factory defaults, the CS141 attempts to obtain an IP address via DHCP. If this fails, it falls back to the default IP address 10.10.10.10.

Forgotten Reboot

The CS141 allows changing the slide switch on the fly and applying the function via software reboot. However, updates can trigger an IP change, making the device temporarily inaccessible.

• When first booting the CS141, set the slide switch to manual mode, enter IP address data, and then perform an update.

• In this case, only the manually entered IP settings will be used.

• Consequently, it may appear that the CS141 cannot be accessed via the hardcoded IP address 10.10.10.10.

Web Browser Caching Issues

Modern web browsers use caching and preloading technologies (e.g., speech recognition, auto-complete, auto-login, personalized content, pre-caching files) to speed up access.

The CS141 uses built-in web-based technology. When multiple CS141 devices are accessed, cached data may overlap, causing incorrect or illogical error messages.

Note: This behavior is caused by the browser cache. Clearing the cache resolves the issue.

Force HTTPS Active

Depending on browser and patch level, some web browsers automatically prepend https to addresses. Others may ignore the query and return confusing results.

Example:

• You enter http://192.168.3.15.

• The browser instead redirects to https://192.168.3.56.

• However, the correct CS141 would have been shown at https://192.168.3.15.

Note: This behavior is caused by the browser. Deleting the browser cache will fix the problem.
