Note:
.swPosition is used to perform the switching via SNMP in Remote Mode.
If .simultaneousMode (chapter 5.9.4.3.3) is set to "
1
" (i.e. Simultaneous
switching mode), a "Set" command issued to .swPosition of a switch unit will
cause all members of the group (to which the switch unit belongs to) to switch.

Syntax:

Access:
read-only
Description:
The number of ports with special properties within the device.
Each amplifier module is considered as a single port.
Description:
The number of ports within the device.
.numberOfPorts is defined here as the number of possible switch
modules (i.e. 16) multiplied with 3, i.e. "
48
" is returned for a
DEV 1953 without applied distribution amplifier modules. The first
distribution amplifier module has the index "
49
", the second
distribution amplifier module "
50
", (and so on).
This means that the range of .numberOfPorts is "
48
"…"
64
".
Example:
"
51
" for a device with 3 installed distribution amplifier modules
Note:
This value determines the maximum index of the following table:
5.9.4.3.9
.application.portTable
The table describes the special features and settings of each port.
Note:
The .portTable distinguishes between the input ports and the output port of a
switch module; the type of port can be identified via .poType (please refer to
chapter 5.9.4.3.9.3).
The maximum index in the .portTable is at least "
48
" independent whether 16
or less switch modules are installed. Empty slots and all slots populated with a
passive module or with a distribution amplifier module are treated (initially) as
"logical" switch modules.
If distribution amplifier modules are installed, the maximum index is 48 plus the
number of installed distribution amplifier modules.
Examples for the occurrence and the sequence of ports in the .portTable:
a) Configuration with 16 switch modules:
Index 1: switch module in the first slot, primary input port ("In A")
Index 2: switch module in the first slot, secondary input port ("In B")
Index 3: switch module in the second slot, primary input port ("In A")
Index 4: switch module in the second slot, secondary input port ("In B")
(…)
Index 31: switch module in the sixteenth slot, primary input port ("In A")
Index 32: switch module in the sixteenth slot, secondary input port ("In B")
Index 33: switch module in the first slot, output port ("Out")
Index 34: switch module in the second slot, output port ("Out")
(…)
Index 48: switch module in the sixteenth slot, output port ("Out")
