EDS-P510 Series Featured Functions
3-23
Email Warning Event Types can be divided into two basic groups: Power-Fail and PD-Failure.
Port Events Warming e-mail is sent when...
Power-Fail When actual PD power consumption exceeds related PD power limit setting.
PD-Failure When the switch cannot receive a PD response after the defined period.
PoE Relay Warning Events Settings

Port Events Warming e-mail is sent when...
Power-Fail When actual PD power consumption exceeds related PD power limit settings.
PD-Failure When the switch cannot receive a PD response after the defined period.
Using Communication Redundancy
Setting up Communication Redundancy on your network helps protect critical links against failure, protects
against network loops, and keeps network downtime at a minimum.
The Communication Redundancy function allows the user to set up redundant loops in the network to provide
a backup data transmission route in the event that a cable is inadvertently disconnected or damaged. This is a
particularly important feature for industrial applications, since it could take several minutes to locate the
disconnected or severed cable. For example, if the EDS-P510 is used as a key communications component of
a production line, several minutes of downtime could cause a big loss in production and revenue. EDS-P510
supports three different protocols to support this communication redundancy function— Rapid Spanning
Tree/ Spanning Tree Protocol (IEEE 802.1W/1D), Turbo Ring, Turbo Ring V2 and Turbo Chain.
When configuring a redundant ring, all switches on the same ring must be configured to use the same
redundancy protocol. You cannot mix the “Turbo Ring,” “Turbo Ring V2,” and STP/RSTP protocols on the same
ring. The following table lists the key differences between each feature. Use this information to evaluate the
benefits of each, and then determine which features are most suitable for your network.
