System compatibility

ISW-4W-4WS-4X belongs to Extreme ISW series industrial managed switch family. SFP combo slots support industrial grade 1G SX, LX, BiDi transceivers; 4 SFP+ uplink ports compatible with Extreme 1G /10G optical modules. Designed for factory floor, transportation, outdoor cabinet and harsh workshop environment. Support resilient industrial ring network to realize automatic link failover.

Function

ISW-4W-4WS-4X is rugged fanless Layer2 industrial PoE switch. Total 8 PoE++ ports deliver up to 90W power for industrial PTZ camera, high-power industrial Wi-Fi AP and other PoE powered field devices. Combo ports can choose copper RJ45 or fiber SFP media. 4 SFP+ slots provide high-speed 10G fiber uplink. Supports VLAN, QoS, IGMP snooping, storm control, port security, alarm relay and network monitoring. Industrial ring protocol ensures rapid recovery when network cable fails. Fanless design avoids fan failure risk in dusty environment.

Installation

Mount the switch on standard DIN rail or equipment cabinet wall. Connect protective earthing wire. Connect dual redundant DC power supply. Connect copper cables or insert industrial SFP transceivers and fiber cables. Configure via serial console or remote management. Verify PoE power output, ring topology status and uplink link after commissioning. Pay attention to thermal limit: under high temperature, system will automatically reduce PoE power to protect device.

FeatureOriginal Extreme ISW-4W-4WS-4X fanless industrial managed PoE switch,8×90W 802.3bt PoE++ ports including 4 combo SFP/RJ45 ports,4×10G SFP+ uplink slots,wide temperature -40~+70℃,DIN rail mount,dual DC redundant power,support industrial ring redundancy. This spare is designed for factory harsh environment industrial PoE field network.

DiagnosticDevice undetected: Check dual DC power input, power wiring and protective ground. PoE port no power: Verify PD compatibility, check PoE configuration and total PoE budget; check thermal throttling status. Combo port link down: Select correct SFP industrial transceiver, inspect fiber quality and fiber polarity. SFP+ uplink port no link: Confirm compatible optical module, fiber condition and port speed negotiation. Ring network interruption: Inspect ring cable connection and ring protocol configuration. Over-temperature warning: Check cabinet ventilation; switch will reduce PoE power or shut down ports to protect hardware.
