4.1
Delivery state/factory default
4.1.1
Initial IP configuration in the delivery state
The PN versions do not have an initial IP configuration in the delivery state.
4.1.1.1
Firmware revision 2.72 and earlier
The device does not have an initial IP configuration.
4.1.1.2
Firmware revision 2.80
In the delivery state, the device has an initial static IP configuration, which enables you to
access the web-based management and to assign an IP address.
–
IP address: 169.254.2.1
–
Subnet mask: 255.255.0.0
This initial IP configuration is deactivated as soon as the switch is assigned an IP configu-
ration via a different IP address assignment mechanism, e.g., via BootP, DHCP, web-based
management.
4.1.1.3
Firmware revision 2.90 or later
In the delivery state, the device has an initial IP configuration and an individual DNS host
name. This way, you can access the web-based management and configure the device.
In the factory default state, the device adopts an IP address from the link-local network
(169.254.0.0/16). IP address 169.254.2.1 is preferably selected, provided it is not already
present in the network. In this way, you can specifically configure individual devices via this
IP address. To avoid IP address conflicts when starting multiple devices simultaneously,
conflict detection is also active. If the switch detects that the adopted IP address is already
assigned, it chooses another one at random.
