DIB-500 R4.1 Setup and commissioning
Connecting Ethernet cables
The voltage source on site must be de-energised.
The toggle switches must be set to the "Off" position ("downward" switch position).
The top cover of the equipment rack must have been removed.
Depending on the connection variant, the plug with earthing contact may have to
be removed already.
The reference potential must have been defined.
Carry out the following steps:
Cable damage
If cables are routed over sharp edges or in bending radiuses too small for the cables,
the cables may be damaged.
Never route cables over sharp edges and always maintain to the bending radius.
Risk of damage
The product may be damaged if the live wires of the voltage supply cable are connected
without grounding.
Connect the green-yellow grounding cable of the grounding conductor first.
Connect the power supply cable(s) at installed rectifier modules – depending on
the connection variant – with the voltage source, see Figure 5.17 on page 112.
The voltage supply cable has been connected.
Switching on the Voltage Source Later on
Since the commissioning of the network requires additional work steps that need to be
performed in the equipment rack, the voltage source must stay switched off for the time
being. Switching on the voltage source is required only later on for the configuration.
5.7 Connecting Ethernet cables
All network elements of the ACCESSNET
®
-T IP network are connected to an IP trans-
port network using an external layer-3 switch. For this reason, operating the
DIB-500 R4.1 requires that Ethernet cables are connected according to the overview in
section Figure 3.17 on page 46 to the DIB-500 R4.1. In addition, the Ethernet cables
must be fastened with cable ties in the equipment rack.
As a router, the layer-3 switch ensures the communication between the individual net-
work constituents that each form a separate subnetwork. In addition, the layer-3 switch
facilitates the integration into existing IP transport networks.
