DIP-switch Bank 2 Description - Plug-in Models
SW1 and SW2: Backplane Enable
This feature is only supported on chassis plug-in modules.
When these DIP-switches are in the "DISABLE" position, the Backplane Port of
the plug-in module is isolated from the Ethernet Backplane on the chassis. When
these DIP-switches are in the "ENABLE" position, the Backplane Port is enabled.
This allows Ethernet Backplane connectivity to an adjacent module via the chassis
A/B Backplane Link depending on the switch setting.
SW3: Master/Slave
This feature is only supported on chassis plug-in modules.
Setting this DIP-switch to the "M/SL" position (factory default), allows chassis
mastership to be automatically negotiated by the installed management modules.
When an Network Management Module (NMM2) is installed in the chassis,
the NMM2 will always be the master, otherwise the lowest slot number with a
management module installed will become the chassis master.
To designate the GM3 module as the master of the chassis when a Network
Management Module (NMM2) is not installed, set the DIP-switch on the module to
the Down "M/SL" position, and set the DIP-switch on the other installed management
modules to the Up "SL" position to enable Slave-Only mode.
Only the chassis master can change the configuration settings of other modules.
When Slave Write is enabled on a slave management module, the management
module can be modified by directly connecting to the serial console port.
SW4: Zero Touch
Zero Touch Provisioning (ZTP) utilizes DHCP and TFTP to automatically configure
the module during the initial setup. ZTP can be enabled/disabled using this hardware
DIP-switch or the CLI autoconfig command.
Zero Touch is disabled by default. The ZTP process is configured by setting this
DIP-switch to the UP position (enabled). When ZTP is enabled, the module will
start the DHCP process on power up or module reboot.

2) Installing the Module
Wall Mounting - Standalone Module
The wall mounting height of the module should be less than or equal to 2 meters
(6.6 feet) from the floor.
The standalone module is available with or without integrated mounting brackets.
When using the standalone module with integrated mounting brackets, use the four
mounting holes on the module to secure the module to the wall. The module can
accommodate #6 screws (not included).
Standalone modules without mounting brackets can use the optional mounting
bracket kit (2x 4381). Use the four mounting holes on the module to secure the
module to the wall. The module can accommodate #6 screws (not included).
Installation of the module should be such that the air flow in the front, back, side
and top vents of the switch are not compromised or restricted.
The accessory cables should have their own strain relief and do not pull down on
the module.
Rack Mounting - Standalone Module
The standalone modules with integrated mounting brackets or using the optional
mounting bracket kit can be rack mounted using the optional Rack Mount Shelf
(8260-0). Refer to the Rack Mount Shelf user manual (040-08260-001x) for the
proper installation guidelines. The user manual is available on the iConverter Rack
Mount Shelf product page at:
www.omnitron-systems.com
Follow the same guidelines above when rack mounting the module.
Chassis Mounting - Plug-in Modules
Caution: Use proper ESD protection to reduce the risk of damage to your
equipment.
Carefully slide the module into an open slot in the chassis. Align the module with
the installation guides and ensure that the module is firmly seated against the
backplane. Secure the module by fastening the front panel thumbscrew (push in
and turn clockwise to tighten) to the chassis front.
