Requirements for the layer-3 switch for controller redundancy
For controller redundancy (see section 3.1.9.3 on page 61), it is required that the layer-
3 switch supports the Multiple Spanning Tree Protocol (MSTP) in accordance with IEEE
802.1Q2.
If network elements must be connected to a layer-3 switch, it is required that the config-
uration of the layer-3 switch has been completed.
Connecting network elements with the layer-3 switch
Preparation:
The initial download must have been completed on the corresponding network ele-
ment.
The layer-3 switch must have been configured project-specific.
Carry out the following steps:
Routing of the Ethernet Cable
When connecting the Ethernet cable, ensure that cables are not routed in front of the
fan unit so they do not impair the replacement of fan unit components.
Connect the Ethernet cable to the Ethernet port of the layer-3 switch and to the cor-
responding Ethernet port of the network element, refer to section 3.1.5 on page 45.
You have successfully connected the network element to the layer-3 switch.
