Compatible HPE MSR Router Power Supply

The HPE JG527A#ABA X351 is a 300W internal AC power supply designed for MSR3044, MSR3064, MSR4060 and MSR4080 routers. It converts 100-240VAC input to 12VDC output for network infrastructure. At least one unit is required per chassis, with support for up to two modules in the MSR3044 and MSR3064 or up to four in the MSR4060 and MSR4080 for redundancy.

300W AC Input Thermal and Power Profile

Operating from 110VAC or 220VAC mains, the module delivers 300W of regulated 12VDC power to the router chassis. The unit weighs approximately 2.49 lb and carries WEEE environmental certification. As an internal server power supply, thermal management and acoustic output are governed by the host router’s fan tray and airflow design rather than the supply itself.

Redundancy Upgrade for MSR3044 and MSR3064

Adding a second X351 module to an MSR3044 or MSR3064 provides N+1 power redundancy, eliminating a single point of failure for the router. For MSR4060 and MSR4080 chassis, up to four modules can be installed to match higher availability requirements. The upgrade is worthwhile when continuous uptime is critical and the chassis has available power supply bays.

Questions about this item

How do I install the X351 300W power supply in an MSR4060 and what step is often missed?

Slide the unit into an empty bay until the latch clicks, then secure the retention screw; the missed step is forgetting to tighten that screw, which can cause the supply to unseat under vibration.

What maintenance will the X351 300W supply need during its service life?

Clean the intake vents and internal fan blades every six months with compressed air to prevent dust buildup that reduces airflow and shortens component life.

What limit appears first when the X351 300W supply runs continuously at full load?

The 300 W output ceiling is reached first; sustained draw above that trips the over-current protection and shuts the unit down.
