Cabling the Connectors 29
Cabling the
Connectors
The PathBuilder switch has two Ethernet interfaces, and a number of
Flex-WAN serial interfaces, Ultra-WAN CSU/DSU, T3/E3 WAN, and/or
ATM interfaces, depending on the model. This section describes how to
cable each interface on your switch.
Some network topologies require that a grounding stud, separate from
the AC ground, be provided on the chassis of the networking equipment.
If this is required, ground the PathBuilder S574 ATM tunnel switch by
attaching a permanently connected protective earthing conductor using a
minimum 18 gauge wire with a UL-listed ring lug to a reliably connected
earth ground (see Figure 11).

Connectors
You can cable one or two Ethernet connectors using either 10BASE-T or
100BASE-TX cabling.
For more information about Ethernet connectors and cables, see “LAN
Connector and Cables” on page 85.
