Installation Manual 18 Document #: LTRT-85605
Mediant 600
2.4.1 Connecting to Earth (Ground)
The device must be permanently connected to earth (ground), using an equipment-earthing
conductor.
Protective Earthing
The equipment is classified as Class I EN60950 and UL60950 and must be
earthed at all times.
¾ To earth the device:
1. Connect an electrically earthed strap of 16 AWG wire (minimum) to the chassis'
earthing screw (located on the rear panel), using the supplied washer.
2. Connect the other end of the strap to a protective earthing. This should be in
accordance with the regulations enforced in the country of installation.
2.4.2 Connecting to IP Network
The device's CPU module provides two 10/100Base-TX RJ-45 ports for connectivity to the
Ethernet network (IP network). The dual ports provide Ethernet redundancy.
¾ To connect the device to the IP/Ethernet network:
1. On the CPU module, connect the first Ethernet port (labeled I) directly to the Ethernet
network, using a straight-through RJ-45 Ethernet cable.
2. Optionally, for Ethernet redundancy, connect the second Ethernet port (labeled II) to
the Ethernet network.
The RJ-45 connector pinouts are shown in the figure below:
Figure 2-6: RJ-45 Connector Pinouts
Notes:
• For Ethernet redundancy, it's recommended to connect each of the
Ethernet ports to a different switch.
• When assigning an IP address to the device using HTTP (refer to
'Assigning an IP Address Using HTTP' on page 27), you may be required
to cable the Ethernet port differently.
