Wiring Power Input
Thersttworelatetoalarmdesign:
• PWR/RPS
Theswitchsupportsdualpowerinput,wedenethesepowersource
as Primary Power Supplier (PWR) and Redundant Power Supplier
(RPS). These two DIP switches are designed to provide an alarm
mechanical to monitor the power connective status. If DIP switch is set
to ON means alarm function is enabled.
The remaining four relate to functionality:
• Storm
Storm control is used to prevent the local area network (LAN) from
being disrupted by broadcast or destination lookup failure (DLF)
storm. The storm occurs when broadcast or DLF packets are
generatedandoodintotheLAN,thisexcessivetra󰀩cdegrades
network performance. If the DP switch is set to ON, it means system
will measure broadcast and DLF packets and suppress them if the
threshold is reached.
• QoS
The switch supports two types of QoS, Port-based QoS (Port Priority)
and VLAN Tag-based QoS (802.1p). Port priority is only enabled
on port 1 and port 2 which ingress packets will be handle with high
transmissionpriority.IfVLANpacketswithpre-denedpriorityare
comingintoswitch(anyport),systemwillrefertoit’sspeciedpriority
for transmission.
• Fiber Speed – P9 and P10
For legacy operation, there is a dual-speed support (100BASE-FX /
1000BASE-SX/LX)onswitchberports.Dependingonthenetwork
environment, a user can choose the proper SFP transceiver and set
therelatedDIPswitchforberconnectivity.
