D-Link DXS-PWR300AC 300W Modular AC Power Supply

Serviceable Power for a Compatible Rack Switch The DXS-PWR300AC is a 300W hot-swappable AC power supply with front-to-back airflow for supported D-Link switches. It gives a compatible installation a defined service component rather than relying on a generic replacement. Confirm the exact host and airflow before selecting a spare. The DXS-3400-24TC and DXS-3400-24SC support this module. A supported second power supply can provide redundancy when installed and powered as required by the host. It is an internal modular PSU, not a standalone PoE injector or a UPS. Highlights Designed for the Host Compatible with DXS-3400-24TC and DXS-3400-24SC. Front-to-back airflow. Exact host, module and airflow must match. Service Component 300W AC modular power supply. Hot-swappable in a supported host. One service module supplied; switch sold separately. Practical Planning 85–264 V AC input at 47–63 Hz. Install according to the host hardware guide. 1-year warranty. Key Features Choose the Correct Service Module Check the switch model, hardware revision and the existing module label before ordering. The compatible DXS-3400 models use a defined modular design. Physical similarity or a shared D-Link brand does not make a different PSU or fan compatible. Keep the Airflow Consistent This is the front-to-back airflow version. The rest of the switch cooling system and the rack ventilation must follow the intended direction. Mixing airflow designs can compromise cooling even when a module appears to fit. Replace Without an Unnecessary Rebuild The hot-swappable design supports servicing a compatible powered host under the manufacturer’s instructions. The switch must retain the power and cooling needed during the operation. Use the correct procedure rather than treating hot-swap as permission to remove multiple essential modules together. Understand the Module’s Role A 300W rating describes the PSU’s rated output, not the switch’s constant consumption or a PoE budget. It does not provide battery backup; a suitable UPS is a separate part of power-resilience planning. Plan Access in the Rack Leave enough service clearance to release and withdraw the module safely. Keep cables from obstructing the extraction path, and confirm that the replacement is fully seated. Label a spare clearly so the correct module is available during maintenance. Commission After Replacement Check the host’s status indicators and management alarms after installation. Confirm that the new module is recognised and that power or fan alerts have cleared. Keep the service record and failed component separate for troubleshooting. Summary The DXS-PWR300AC is a purpose-matched power supply for supported front-to-back-airflow D-Link switches. Confirm the host and module identity, maintain the required redundant components and verify the switch after service. Frequently Asked Questions Which Switches Are Explicitly Supported?ExpandCollapse The DXS-3400-24TC and DXS-3400-24SC are explicitly listed. The manufacturer also lists the DXS-3600 series, but exact host and hardware compatibility must be checked for a service replacement. Is This a Complete Switch?ExpandCollapse No. This offer supplies one modular power supply. The compatible switch is purchased separately. Does It Have Front-to-Back Airflow?ExpandCollapse Yes. Match it to the host’s required airflow direction and the rack cooling arrangement. It is not the back-to-front version. Can It Be Hot-Swapped?ExpandCollapse Yes, in a compatible host and under the hardware guide’s service procedure. Maintain the remaining power and cooling requirements while replacing the module. Does It Fit DXS-3610 Switches?ExpandCollapse No compatibility is specified here for DXS-3610. That series uses different PSU and fan families. Check the exact supported service part instead of substituting this module. Does It Provide Battery Backup?ExpandCollapse No. It is an AC power conversion module. A second supported PSU can provide supply redundancy, while battery backup requires a suitable external UPS. 더 보기
