3.2.6 Operating in Unmanaged mode
For operation in Unmanaged mode, the switch can also be used without an IP address. The
switch adopts the static IP address 0.0.0.0. The subnet mask and gateway are also config-
ured to 0.0.0.0. In this way, web-based management can no longer be accessed, and the
switch no longer sends BootP and DHCP requests.
The main functions remain active in Unmanaged mode:
– Redundancy mechanisms for loop avoidance (RSTP, FRD, LTS)
– Functions for hardening the network (broadcast/multicast limiter)
– Functions for reducing the network load (IGMP snooping)
The functions must be configured in Managed mode and will remain active when switching
to Unmanaged mode. Alternatively, Unmanaged mode can be activated using a configura-
tion file and SD card.
3.3 Assigning IP parameters via BootP
For IP address assignment, the device uses the BootP protocol. Numerous BootP servers
are available on the Internet. You can use any of these programs for address assignment.
This section explains IP address assignment using the “FL NETWORK MANAGER Basic”
(Order No. 2702889) and “IP Assignment Tool” software tools from Phoenix Contact.
Notes on BootP
During initial startup, the device sends BootP requests without interruption until it receives
a valid IP address. As soon as it receives a valid IP address, the device stops sending BootP
requests.
After a restart, the device sends three BootP requests and will only then accept the old IP
address if there is no BootP response.
3.3.1 Assigning the IP address using
FL NETWORK MANAGER Basic
Requirements
The device is connected to a PC with a Microsoft Windows operating system and the
FL NETWORK MANAGER has been successfully installed.
Step 1: parameterizing the BootP server
• Open the FL NETWORK MANAGER software
• Open a new project in the software
Unmanaged mode can only be exited by switching to a different Smart mode or by reset-
ting the switch to the factory settings.
BootP is activated by default.
