Operation mode of the web manager
The difference between configuration mode, rescue mode and operation mode
All models of the CS141 family can be configured exclusively via an intuitive web interface. The web managers offer 4 valid
hardware operating states, which are fundamentally different from each other:
1.
The configuration mode
The sliding switch is in centre position
.
Configuration mode is the mode in which the manager is delivered by default. In this mode, the web manager is accessible via a
hardware-preset IP address 10.10.10.10 and allows all system-relevant settings.
Since the manager generally uses the pre-set
IP address in configuration mode, you can also import data backups here and adjust them after restarting.
2.
Der regular operation mode
The slide switch is in the left or right position depending on the setting.
Depending on the setting, the CS141 is in DHCP mode
or manual mode.
Der manual mode
In manual mode, you define the IP address data as a software feature: Please note that incorrect settings may lead to address
conflicts in the network or the settings made may not work. The data required for manual mode can be obtained from the local
administrator. As a special feature, within the manual mode, you may choose between DHCP / manual IP address for both, IPv4
and IPv6 independent to each other.
Note:
In manual mode, the data is entered by technicians and thus permanently assigned. The CS141 will use this data to make itself
known in the network. assigning an address twice will cause a network conflict. In this case, switching back to configuration
mode at any time is possible to reach the Web Manager at the default IP address 10.10.10.10.
Der DHCP Modus
In DHCP mode, the CS141 automatically inherits settings assigned by a server and uses them for the IP address settings. The
web server takes over the administration of the IP address data. After the start-up process, the web manager can be found
using the tool Netfinder.
Tipp:
As a rule, DHCP-assigned IP addresses via automatic mode are reserved for specific time.
DHCP clients therefore ask after 50% of this time window whether the IP address is still valid or will be assigned to another
client. How statically the DHCP server allocates IP addresses is a decision the system administrators make.
Due to this fact another IP address can be re-assigned after booting or a CS141 seems to be lost during regular operation.
When selecting the operating mode, the function of the CS141 within the network should be considered:
If the Web Manager runs as an active element within shutdown solutions or in conjunction with higher-level monitoring
structures, a manually assigned IP address makes sense, since an authenticated and fixed IP address must be configured.
As another advantage the CS141 starts faster with preconfigured IP addresses if the DHCP server is not available.
3.
The rescue mode
In this mode, an additional jumper is set and the slide switch centre position.
The webmanager can access two ROMs for booting. Therefore, this failsafe design is able to contain the current firmware as
well as the last state before the firmware update including the configuration file.
When the web manager is set to rescue mode, the logic starts from the last known state and is initially fully operational again but
indicates in the general system information that the web manager is in rescue mode.
The rescue mode represents a manually chosen emergency operation state and is intended to repeat a faulty flash process
