Controlling the E5250A
Switch Control Basics
Connection Rule Connection rule is used to specify if an input or output port can have multiple
connections, and it is specified by the [:ROUTe]:CONNection:RULE command
described in Chapter 7. For each card installed in the E5250A (for auto
configuration mode, installed cards are treated as one card), you can specify one of
the following connection rules:
Single Route: Each input port can be connected to only one output port, and
each output port can be connected to only one input port. So,
existing connection to a port must be disconnected when a new
connection is made.
If normal configuration mode is set to the E5250A with
multiple cards, an input/output path is effective for each card.
For example, if normal configuration mode is set to the E5250A
with two E5252As, and single route is set to both cards, the
following connection is possible.
Free: Each input port can be connected to multiple output ports, and
each output port can be connected to multiple input ports.
CAUTION If the Free connection rule has been specified, ensure multiple input ports are not
connected to the same output port. Such configurations can cause damage.
