Maintenance
Overview
When the Zyxel Device is set to work in cloud managed mode, the Maintenance screens allow you to upload firmware, manage shell script files, generate a diagnostic file, view log messages, or reboot the Zyxel Device.
Firmware Package
Use the Firmware Package screen to check your current firmware information and upload firmware to the Zyxel Device. You can manually download the new firmware from the Zyxel website.
The Web Configurator is the recommended method for uploading firmware. You only need to use the command line interface if you need to recover the firmware. See the CLI Reference Guide for how to determine if you need to recover the firmware and how to recover it.The firmware update can take up to five minutes. Do not turn off or reset the Zyxel Device while the firmware update is in progress!
The Zyxel Device automatically reboots after a successful upload.Label | Description |

Version | |
Current Version | This is the firmware version. |
Released Date | This is the date that the version of the firmware was created. |
Upload File | |
File Path | Enter the location of the file you want to upload in this field or click Browse... to find it. |
Browse... | Click Browse... to find the .bin file you want to upload. Remember that you must decompress compressed (.zip) files before you can upload them. |
Upload | Click Upload to begin the upload process. This process may take up to two minutes. |
The Zyxel Device automatically restarts causing a temporary network disconnect to devices connected to its network.After five minutes, log in again and check your new firmware version in the Dashboard screen.
Shell Script
A shell script is a list of commands to manage the Zyxel Device. Use a text editor to create the shell script files. They must use a “.zysh” filename extension. For example, test.zysh.
Use the Shell Script screen to store, name, download, and upload shell script files. You can store multiple shell script files on the Zyxel Device at the same time.
1 In the text editor, save the shell script with a .zysh filename extension. Select All Files as the file type.
2 Click Browse... to upload the .zysh file.
3 Click Upload. The uploaded shell script will be shown in the Shell Scripts field.
Each field is described in the following table.

Legal and Regulatory
Use this screen to view the information on legal and regulatory. This screen may not display depending on the Zyxel Device model you are using.
Diagnostics
This screen provides an easy way for you to generate a file containing the Zyxel Device’s configuration and diagnostic information. You may need to generate this file and send it to customer support during troubleshooting. All categories of settings and shell script files stored on the Zyxel Device will be included in the diagnostic file.
Click Collect Now to have the Zyxel Device create a new diagnostic file.
The Debug Information Collector screen then displays showing whether the collection is in progress, was successful, or has failed. When the data collection is done, click Download to save the most recent diagnostic file to a computer.
Remote Capture
Use this screen to capture network traffic going through the Zyxel Device and output the captured packets to a packet analyzer (also known as network or protocol analyzer) such as Wireshark. If the Zyxel Device is connected to the Zyxel gateway or ZyWALL, you might need to configure the Zyxel gateway or ZyWALL to allow remote capture on the Zyxel Device.
The following table describes the labels in this screen.
Label | Description |
|---|---|
Server Port | Enter the number of the server port you want the packet analyzer to connect to in order to capture traffic going through the Zyxel Device. The default port number is 2002. |
Start | Click this button to allow the packet analyzer to start capturing traffic going through the Zyxel Device. |
Stop | Click this button to stop the packet analyzer from capturing traffic going through the Zyxel Device. |
View Log
The NCC periodically gathers log files from the devices being managed by it. Before the NCC pulls logs from the Zyxel Device or when the Zyxel Device is disconnected from the NCC, you can use this screen to view its current log messages.
When a log reaches the maximum number of log messages, new log messages automatically overwrite existing log messages, starting with the oldest existing log message first.Events that generate an alert (as well as a log message) display in red. Regular logs display in black. Click a column’s heading cell to sort the table entries by that column’s criteria. Click the heading cell again to reverse the sort order.
The following table describes the labels in this screen.

If you made changes in the CLI, you have to use the write command to save the configuration. They do not change when you reboot the Zyxel Device.
Reboot is different to reset; reset returns the Zyxel Device to its default configuration.
You can reboot your Zyxel Device when the Internet connection is slow or intermittent.
Each field is described in the following table.
Label | Description |
|---|---|
Reboot | Click Reboot then click Yes to restart the Zyxel Device immediately. |
After the Zyxel Device reboots, wait a few minutes until the login screen appears. If the login screen does not appear, type the IP address of the Zyxel Device in your Web browser.
You can also use the CLI command reboot to restart the Zyxel Device.
