THE FBVi INTEGRATED ETHERNET SWITCH
The
FBVi-2U4-4T
includes an integrated
Ethernet Switch
, with 2 ports. This allows the device to forward
IP
packets from each port to the other, allowing
FBVi
,
FBXi
and
CBXi
devices to be connected in a
Daisy-
Chain
topology:
It is recommended is that both ends of an
FBXi
/
FBVi
/
CBXi
daisy chain network are connected to a
single switch that supports the
Spanning Tree
network switch protocol (STP). In this scenario a single line
break or controller failure in the loop will allow all controllers to continue to communicate.
For example, if
controllers
A
,
B
,
C
,
D
and
E
are daisy-chained, connected on both sides, with a single switch
supporting
Spanning Tree Protocol
:
•
If
controller
B
loses power,
controller
A
will be on one trunk, and
C
/
D
/
E
will be on another all
communicating.
•
If controllers
B
and
D
lose power, controllers
A
and
E
will communicate, but controller
C
will not.
Note
: The
FBVi Series
controller has a pass-through across its IP switches, such that if it loses power
controllers ‘downstream’ will continue to be connected
. Only the
FBVi Series
has this feature.
Note
: If you plug both ends of the daisy chain network into a switch that does not support the
Spanning Tree
Protocol
, it will flood the network with requests. The switch will send and receive the same messages
over and over again, until something breaks.
CONFIGURING THE IP CONNECTION
Configuring the IP connection using CXpro
ᴴᴰ
CXpro
ᴴᴰ
includes a utility to quickly configure
BACnet
properties for
IP
devices. To launch this utility,
right-click on a
Site
in the
Site List
and select
Configure IP BACnet Device Properities
The utility will scan for all
CBXi
,
FBXi
and
FBVi
devices on the selected network.
Note
: The devices must be configured within
CXpro
ᴴᴰ
before they can be accessed by this utility.
