PI
DIP-switch Bank 2 is only available on the plug-in module.
Switch Left (Factory Default) Right
SW1 A-DS:
Backplane Port A Disabled
A-EN:
Port A Enabled
SW2 B-DS:
Backplane Port B Disabled
B-EN:
Port B Enabled
SW3 Reserved Reserved
SW4 M/SL:
Master/Slave Auto-Select
SL:
Slave-Mode Only
SW5 - SW8 Reserved Reserved
3.2.2.1 SW1 - Backplane Port A Enabled “A-DS/A-EN”
When the DIP-switch is in the Left “A-DS” position (factory default), Backplane Port A of the 2FXM2 is
isolated from the chassis Backplane. When the DIP-switch is in the Right “A-EN” position, Backplane
Port A of the 2FXM2 is enabled. This port allows Ethernet Backplane connectivity to an adjacent module
via the chassis Backplane Port A. See the backplane illustrations in Section 2.1.3.
3.2.2.2 SW2 - Backplane Port B Enabled “B-DS/B-EN”
When the DIP-switch is in the Left “B-DS” position (factory default), Backplane Port B is isolated from the
chassis Backplane. When the DIP-switch is in the Right “B-EN” position, Backplane Port B is enabled.
This port allows Ethernet Backplane connectivity to an adjacent module via the chassis Backplane Port B.
See the backplane illustrations in Section 2.1.3.
3.2.2.3 SW4 - Master/Slave Auto-Select and Slave-Only “M/SL / SL
When multiple management modules such as the iConverter Network Management Module (NMM) and
the 2FXM2 (or multiple self-managed modules such as the 2FXM2) are installed in the same chassis, only
one management module can act as the chassis master. The master management module has the ability to
make changes to the settings of the other modules in the chassis, while the slave management modules
cannot make the changes. If an NMM is installed in the chassis, the NMM will always be the master,
otherwise the lowest slot number with a management module installed will become chassis master.
When this DIP-switch is in the Left “M/SL” position (factory default), the assignment of mastership is
automatically negotiated by the installed management modules. To designate a specific management module
as the master when no NMM is installed in the chassis, set the DIP-switch on the master module to the Left
“M/SL” position, and set the other installed management modules’ DIP-switches to the Right “SL” position
to enable Slave-Only mode.
Only the chassis master can change configuration settings of other modules.
3.2.2.4 SW3, SW5, SW6, SW7, SW8 - Reserved
These DIP-switches are for factory use only.
NOTE: DIP-switches marked Reserved must be kept in the Left (factory default) position.
