Extreme Networks DS450DC-3 Power Supply Module

Technical SpecificationsModel: DS450DC-3 Brand: Extreme Networks Product Type: Hot-swappable DC power supply module for rack switch Mounting: Install into power slot of X440-G2 chassis Operating temperature:0℃ ~ +50℃ Storage temperature:-40℃ ~ +70℃ Relative humidity:10%~95%, non-condensing Input: -48V DC (36~72V DC wide range) Output power:450W max Cooling: Built-in fan, airflow same as switch Weight:1.2 kg

System compatibilityDS450DC-3 is dedicated DC power supply for Extreme Networks X440-G2 series switches. It can work as primary or redundant PSU, compatible with X440-G2-12P-10, X440-G2-48P-10. Widely used for enterprise campus PoE switch maintenance and spare replacement.

FunctionDS450DC-3 converts -48V telecom DC input into multiple DC rails to supply power for switch mainboard, PoE subsystem and fans. It monitors output voltage, current, internal temperature and fan speed. It triggers alarm once over-current, over-temperature, input power loss or fan failure occurs. Used for replacing failed power modules on X440-G2 PoE switches.

InstallationPower off chassis before installation. Insert DS450DC-3 into the empty power slot and lock the latch. Connect -48V DC power cable to terminal block. Verify module detection by switch ExtremeXOS, check power status and PoE budget before putting into production.

InterfaceDC input terminal block, internal chassis power connector, status LED indicators for Extreme Networks DS450DC-3.

FeatureOriginal Extreme Networks DS450DC-3 telecom DC power module, hot-swappable, 450W power output, over-current / over-voltage / over-temperature protection, built-in self-diagnostic function. This spare supports enterprise PoE switch redundant power deployment.

DiagnosticPower module no LED: check -48V DC input power and terminal wiring. Power alarm: verify input voltage range, overload condition and internal temperature. Fan fault alarm: check fan rotation and air inlet blockage.

Product BriefDS450DC-3 is Extreme Networks 450W hot-swappable -48V DC power supply module for X440-G2 series PoE switches, used for redundant power or PSU replacement, classic spare part for campus access network overhaul.
