Network uptime depends on the stability of your power source. The Juniper JPSU-350-AC-AFO provides the energy needed to keep your EX4300 series switches operational 24/7. This 350W AC module is a field-replaceable unit designed for high-availability environments.
This power supply delivers a consistent 350 watts to handle the demands of data-heavy networking. It supports the full range of EX4300 features without bottlenecking performance. Engineers choose this unit for its high power conversion efficiency and low thermal footprint.
Cooling is a major factor in hardware longevity. The AFO (Airflow Out) design pulls air from the front of the switch and exhausts it through the back. This matches the cooling requirements of most modern data centers using cold-aisle containment.
Maintaining a zero-downtime environment requires hardware that can be serviced while active. The Juniper JPSU-350-AC-AFO supports hot-swapping, meaning you can replace a module without powering down the switch. This feature prevents network interruptions during routine maintenance or hardware failures.
Compatibility is never an issue with this genuine Juniper component. It fits perfectly into the rear slots of the EX4300-24T, EX4300-48T, and other models in that specific family. The physical form factor ensures a snug fit and secure connection to the internal backplane.
The unit accepts a wide range of input voltages from 100V to 240V AC. This flexibility makes it suitable for global deployments in various regions. It also operates effectively within the standard 50Hz to 60Hz frequency range.
Juniper engineers integrated several safety features into the JPSU-350-AC-AFO. It includes over-voltage protection to shield the switch from power spikes. Over-current and short-circuit protection are also standard to prevent damage to the internal logic boards.
Lowering the Total Cost of Ownership (TCO) is a priority for IT managers. This power supply operates at peak efficiency to minimize wasted energy. Less waste heat also means your rack-level cooling systems don’t have to work as hard.
Troubleshooting is faster with clear visual feedback. The module features front-facing LEDs that indicate power status and fault conditions. Network technicians can identify issues at a glance without logging into the management console.
Industrial-grade components allow this PSU to function in varying temperatures. It maintains performance even in high-density racks where ambient temperatures can rise. Reliability remains steady under full load during peak traffic hours.
Buying authentic hardware is the only way to ensure warranty coverage and support. Counterfeit power supplies can damage your expensive switching fabric and void your contracts. You should always work with a verified Juniper Networks dealer in India to secure original parts.
Choosing the right power module protects your broader infrastructure investment. The JPSU-350-AC-AFO is built to last through multiple hardware refresh cycles. Its durable construction withstands the rigors of 24/7 enterprise operation.
Installing the module is straightforward and requires no tools. Simply align the unit with the power supply slot on the rear of the switch and slide it in until it clicks. Tighten the captive thumb screws to ensure it remains seated during vibration or movement.
Deploying dual power supplies in your switches is a best practice for mission-critical sites. This configuration provides a safety net against circuit failures or internal module faults. The JPSU-350-AC-AFO makes this level of reliability accessible and easy to implement.
A fluctuation in voltage can cause logic errors in high-speed ASICs. The Juniper JPSU-350-AC-AFO acts as a buffer between the raw utility power and the delicate switch internals. It filters noise and provides a clean stream of electricity to the EX4300 chipset.
The power supply communicates directly with the Junos operating system. This allows administrators to monitor power consumption in real-time through the command-line interface. You can track wattage usage and temperature metrics to predict when a module might need attention.
Choosing the right airflow direction is vital for rack health. AFO (Airflow Out) is the standard for cabinets where cold air enters the front. If your data center pulls air from the back, you would need the AFI variant instead. Always verify your rack layout before purchasing to ensure thermal efficiency.
The unit contains internal sensors that monitor heat levels. These sensors adjust the fan speed dynamically based on the current load. This prevents the power supply from becoming too noisy while still protecting the sensitive internal circuits.
Juniper tests these power supplies to meet high Mean Time Between Failure (MTBF) standards. You can expect years of service even when the switch is operating at maximum throughput. This durability makes it a smart choice for core network infrastructure.
Electricity from the grid is not always stable. The JPSU-350-AC-AFO is designed to handle minor power sags without rebooting the switch. This level of input tolerance keeps your data flowing during brownouts or grid switching events.
Juniper is committed to reducing the environmental impact of its hardware. The JPSU-350-AC-AFO meets strict energy efficiency standards. Using fewer watts for the same output helps organizations reach their green energy goals while saving on operational costs.
EX4300 switches are often used in Virtual Chassis configurations. In these setups, losing a single switch due to power failure can disrupt the entire stack. Equipping each unit with a JPSU-350-AC-AFO ensures that the stack remains stable even if a power cord is accidentally unplugged.
The metal casing of the JPSU-350-AC-AFO is built to provide electromagnetic shielding. This prevents the power supply from interfering with the high-speed data signals in the switch. It also protects the power unit itself from external interference in noisy equipment rooms.
Whether your facility runs on 110V in North America or 220V in Europe and Asia, this PSU handles it. The auto-sensing technology automatically adjusts to the input voltage. This makes it a standard part for global organizations with distributed branch offices.
Using the original JPSU-350-AC-AFO qualifies you for Juniper support services. If a hardware fault occurs, Juniper technical assistance can diagnose the issue through the switch logs. Third-party power supplies often lack the sensors needed for this deep level of diagnostic reporting.
The Juniper JPSU-350-AC-AFO is more than just a power brick. It is a critical component for maintaining high-speed data flow across your enterprise. Trusting your power needs to genuine Juniper hardware ensures your network remains fast and resilient.
