Juniper JPSU-H-340W-E-DC DC PSU for EX4100-H-12MP-DC | Enterprise

Protect switch uptime with a replacement power module built for the EX4100-H-12MP-DC platform. The Juniper JPSU-H-340W-E-DC is a 340 W DC power supply intended for compatible EX4100-H deployments where exact-fit replacement matters. In network environments, power hardware is not a commodity part; it is a platform-specific component that must align with the chassis design, service workflow, and operational expectations of the switch. This PSU is a practical choice for teams that keep validated spares on hand and want a direct replacement path when a power module fails. By matching the supported platform, it helps reduce troubleshooting time and avoids the uncertainty that comes with non-OEM alternatives. That translates into faster restoration, cleaner maintenance procedures, and less disruption to access, aggregation, or edge switching roles. For organizations that run Juniper switching in production, the value is straightforward: preserve service continuity, simplify field replacement, and keep the hardware stack supportable over time. When uptime is measured in business impact, a verified replacement PSU is a small part that protects a much larger investment.
