How to install Extreme Networks SDR-240-48 Power Supply

• Prepare the enclosure: Ensure the equipment rack or cabinet has adequate space and proper airflow to accommodate the SDR-240-48 and its load. Confirm that the enclosure is grounded and compliant with local electrical safety standards.
• Power down and isolate: Before handling any power connections, switch off all power sources to the chassis and disconnect from the main power supply to prevent accidental energization.
• Mount on DIN rail: Align the SDR-240-48 with the DIN rail in the enclosure and secure it using the appropriate mounting clips or screws. Verify that the unit is firmly seated and does not slide along the rail.
• Connect input power: Attach the appropriate input connectors for your region (120 V AC or 230 V AC, or the designated DC input). Ensure correct polarity for DC inputs and use proper wire sizing and cable management to minimize resistance and heat buildup.
• Wire the output to your load: Connect the 55 V DC output to the power input terminals of your networking devices, observing correct polarity and using secure, rated connectors. Route cables to prevent interference and maintain tidy cable management within the enclosure.
• Inspect and test: Double-check all connections for tightness and correct routing. Reconnect the main power, power on the system, and verify that the SDR-240-48 powers up correctly and delivers stable 55 V DC to the connected devices. If available, monitor device indicators or use a multimeter to confirm voltage stability.
