EDS-405 User’s Manual
Moxa Turbo Ring Setup
EDS-405 is the first plug-n-play unmanaged redundant Ethernet switch in the
world. EDS-405’s ports 4 and 5 are used to form a Turbo Ring. When forming
the ring, connect either port 4 or 5 of one switch to port 4 or 5 of a neighboring
switch. EDS-405 does not support ring coupling.
There are 6 Dip Switches on the top panel of EDS-405. The default setting of the
Dip Switches is OFF. Dip Switches 1 to 5 are for enabling Port Alarms.
Dip Switch 6 is for enabling the EDS-405 to be the Ring Master, and for
enabling the Turbo Ring break alarm. To designate a Ring Master, enable any
EDS-405 on the network to be the Ring Master of the Turbo Ring by setting its
Dip Switch 6 to ON. If you accidentally set more than one EDS-405’s Dip
Switch 6 to ON, then those EDS-405s whose Dip Switch 6 is set to ON will
auto-negotiate to determine which one will be the Ring Master. If you don’t
enable any EDS-405 to be the Ring Master by setting Dip Switch 6 to ON, Turbo
Ring protocol will choose the EDS-405 that has the smallest MAC address range
to be the Ring Master. Another function for Dip Switch 6 is to enable the Turbo
Ring break alarm.
NOTE
All managed EDS Series and EDS-405 Series switches have the
Turbo Ring feature. However, If you wish to use different
models of switch in the same Turbo Ring, you will need to
upgrade the firmware for the managed EDS Series switch, and
EDS-405. To do this, download the latest version of firmware
and utility for the managed EDS Series switch that is compatible
with EDS-405, and the latest firmware and utility for EDS-405,
from www.moxa.com, and then upgrade the firmware of all of
the switches in the ring. If you have any questions about this
procedure, contact the Moxa Technical Support Team.
