Port Redundancy
DIP-switches SW4 and SW5 control the port redundancy mode of the module.
When SW5 is in the “NORM” (factory default) position, the ports operate in a non-
redundant (independent) mode. When SW5 is in the “1:1” position, the module is
configured for port redundancy and operates based on the position of SW4. When
SW4 is in the “RTP” (factory default) position, the module will switch back to the
primary port (Port 1) once a stable connection has been established. When SW4
is in the “OFF” position, the module will remain on the backup port (Port 2) even
when a stable connection has been established on Port 1. See Port Redundancy
Modes table for more information.
NOTE: The ports must have MAC learning disabled to perform a 50msec
switch over.

Port Redundancy Modes
SW6 and SW7 - Reserved
This DIP-switch is reserved and must be in the DOWN (default) position.
SW8 - Zero Touch Provisioning
Zero Touch Provisioning (ZTP) utilizes DHCP and TFTP to automatically configure
the module during the initial setup.
Zero Touch is disabled by default. The Zero Touch Provisioning (ZTP) process
is configured by setting this DIP-switch to the UP position (ON). When ZTP is
turned ON, the module will start the DHCP process on power up or module reboot.
Through the process, the module will request an IP address and the IP address
of the TFTP Server. After the DHCP process has been completed and a TFTP
Server IP address has been obtained, the module will request configuration files
from the TFTP Server. When the files have been received, the module will load
the configuration files and restart.

2) Installing the Module
Wall Mounting
The wall mounting height of the module should be less than or equal to 2 meters
(6.6 feet) from the floor. 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
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.
Follow the same guidelines above when rack mounting the module.
