For this configuration step, navigate to the following menus:
Note:
If possible, do not disable the web server!
In order to fit with some high-security compliance conditions, it may be desirable that the web interface of CS141 has to be switched off after configuration work. The CS141 operates exactly "as configured". But it will be a little bit awkward if you need to change or add settings afterwards.
For security reasons, there is no console access. Configuration work will be done via a standardized web interface.
Webserver setting
HTTP or HTTPS - Port settings
Setting up the HTTP port
The international standard for web access is port 80 - normally this port does not have to be changed. Anyway, since this is not a fixed standard, your IT infrastructure manager may use settings that differ. If this is necessary, you may use this setting to fit your IT infrastructure right here.
Please note, if you use a custom port setting, you need to name the according port for web access.
o 192.168.3.1:85
In this example, the WEBMANAGER will only be accessible at the IP 192.168.3.1 and the port 85. With port 80, you would run into an error message that is generated by your web browser.
The HTTPS Port
In case of using HTTPS, the standard port is port 443. Like the HTTP port, you may use this setting to define custom ports for HTTPS access.
Note:
As soon as force HTTPS is active,
https://is mandatory for direct web access to the CS141. If you miss to use this syntax, there are two different types of web browser behavior:Connection Timeout
Since CS141 answers in case of an HTTPS query, the web browser waits some time and shows a connection timeout issue.
Forwarding (depends on the web browser in use)
If several CS141 devices in your network are configured to use HTTPS only, your web browser may think you entered the wrong IP address and forward you to another device.
Force HTTPS
A standard HTTP connection on the Internet can easily be intercepted by intruders. In order to avoid this and to ensure secure data transmission, an HTTPS connection is recommended to be used. By doing so, the connection is encrypted, and the server is authenticated.
The advantage is increased data security, but at the cost of an increased response time, since the data is transmitted encrypted.
Force HTTPS prevents regular HTTP traffic and enforces the use of HTTPS.
HTTP Refresh Time
The CS141 provides dynamic update system status pages. Among other things, these pages display the status and many values of the UPS the CS141 is connected to. By default, the CS141 updates displayed screens every 10 seconds, but you may choose your own refreshing time.
Use simple monitor
The CS141 offers two different displays as a UPS monitor, which differ in terms of layout and content:
The simple monitor (Fig. Right) contains significantly less information, but better legibility.
Enable HTTP Tooltips
Tooltips are context-related pop up screens that appear automatically as soon as you move the mouse over a setting option.
As a default, the tooltips are enabled. Unchecking this box will disable the tooltips.
How to Enable / Disable the webserver
With Services>Setup, the CS141 provides functions to disable the built-in Web server service.
Note:
The user interface depends on the web server – afterwards, you cannot carry out any further configuration or access the monitoring screens. For interface access, resetting the device to factory default settings is mandatory.
