100 m (max) crossover cable. Cat. 5(e)
Screened Twisted Pair crossover cable (transmit and receive) is required
between switches.

To prevent ground loops, build this cable
assembly with a shielded, metal-enclosed RJ45 connector on one end and an
isolated, plastic-enclosed RJ45 connector on the other end. The metal connector
end of this cable assembly/link can be placed on either switch.

100 m (max) straight-through cable. To
prevent ground loops, build this cable assembly with a shielded, metal-enclosed
RJ45 connector on one end and an isolated, plastic-enclosed RJ45 connector on
the other end. The metal connector end of this cable assembly/link
must be placed on the switch and
not on the PC.

100 m (max) straight-through cable. The
shield on the controller's RJ45 connector connects only to a Faraday cage in
the controller; not to the controller's DC ground. Therefore, the RJ45
connectors are floating and the single point of ground is made at the hub or
switch to which the controller is connected. Build this cable assembly with a
shielded, metal-enclosed RJ45 connector on
both ends .

If switch management is to be used over
the network via telnet or a web browser, be aware that access privileges and
port configuration requirements exist for the twisted pair switch-to-switch
links. Refer to "Managing Cisco Switches" in Books Online for information.
Refer to for the list of reserved IP addresses that are allowed for switches on
DeltaV systems. Refer to the Cisco documentation for web management
information. A dedicated non-DeltaV PC is required for switch management.

The Management station has special
hardware and software requirements. Refer to the related topics for information
on the management station before connecting the station to the DeltaV Control
Network.
