Juniper JPSU-400W-DC-AFI 400W DC PSU FRU | Power Supply, Enterprise

Restore power quickly when a failed supply threatens uptime. The Juniper JPSU-400W-DC-AFI is a 400 W DC field-replaceable power supply unit designed for supported Juniper platforms that require dependable replacement hardware. In environments where maintenance windows are short and network interruption is expensive, a verified FRU keeps recovery straightforward and reduces time spent sourcing compatible parts. This module is intended for teams that standardize on exact-fit replacement components rather than generic alternatives. That matters in production switching environments, where electrical compatibility, mechanical fit, and predictable service behavior are part of the purchase decision. A dedicated DC PSU FRU helps preserve operational continuity, supports faster repair workflows, and gives infrastructure teams a known-good replacement path when power hardware reaches end of life or fails unexpectedly. For procurement and operations teams, the value is in reducing risk. Instead of delaying restoration while validating third-party compatibility, this part aligns with the original platform design and supports a cleaner maintenance process. It is a practical choice for organizations that need to protect uptime, simplify spares planning, and keep network infrastructure serviceable over the long term.
