User's Manual of LRP-822CS
PoE Usage Monitoring
Via the power usage chart in the web management interface, the LRP-822CS enables the administrator to monitor the status of
the power usage of the connected PDs in real time. Thus, it greatly enhances the management efficiency of the facilities.
PoE Over-temperature Protection System
The over-temperature protection of the LRP-822CS offers a safe and stable PoE operation by limiting the output power in
order to avoid destructive breakdown due to unexpected overheating.
Environment-friendly, Smart Fan Design for Silent Operation
The LRP-822CS features a 19-inch metal housing, a low noise design and an effective ventilation system. It supports the smart
fan technology to automatically control the speed of the built-in fan to reduce noise and maintain the temperature of the PoE
switch for optimal power output capability. The LRP-822CS is able to operate reliably, stably and quietly in any environment
without affecting its performance.
IPv6 / IPv4 Dual Stack
Supporting both IPv6 and IPv4 protocols, the LRP-822CS helps the SMBs to step in the IPv6 era with the lowest investment as
its network facilities need not be replaced or overhauled if the IPv6 FTTx edge network is set up.
Robust Layer 2 Features
The LRP-822CS can be programmed for advanced switch management functions such as dynamic port link aggregation,
802.1Q VLAN and Q-in-Q VLAN, Multiple Spanning Tree Protocol (MSTP), Loop and BPDU Guard, IGMP Snooping, and
MLD Snooping. Via the link aggregation, the LRP-822CS allows the operation of a high-speed trunk to combine with multiple
ports such as an 8Gbps fat pipe, and supports fail-over as well. Also, the Link Layer Discovery Protocol (LLDP) is the Layer 2
Protocol included to help discover basic information about neighboring devices on the local broadcast domain.
