Clear-com HLI-ET2 Ethernet Interface Module
Clear-com HelixNet HLI-ET2 is a dual port* Ethernet
switch interface module for the
HMS-4X*** main station.
Interfacing
HLI-ET2 can be added to any HMS-4X*** main station
with an available option
slot. Once installed, the system can be
centrally managed from the browser-based
Core Configuration Manager™
(CCM**).
*Both ports are configured to bridge traffic from one port
to the other in order to work in daisy-chain. Spanning Tree
Protocol is
not enabled on those ports. Do not connect them both to the same network.
**CCM requires HLI-ET2
***HMS-4X is a legacy product as of 2022
