Product identity

The HPE Juniper Networking EX4300-24P is a 24-port Gigabit Ethernet switch with PoE+ capability. It delivers Layer 3 routing in a 1U rackmount form factor for enterprise access deployments. The unit includes a 715 W AC power supply that provides 565 W of PoE+ budget. Network managers needing wired connectivity and power for access points or IP phones will find the port density suitable.

Thermals noise and power

The 715 W AC supply feeds both system operation and up to 565 W of PoE+ power across the 24 ports. Fan speed adjusts to internal temperature so acoustic output rises only when the chassis warms under combined data and PoE load. Typical office deployments see modest airflow and low audible noise. Power draw scales with the number of powered devices attached to the switch.

Sustained load behaviour

Under continuous full-port utilisation the PoE budget remains capped at 565 W while the switching fabric handles line-rate Gigabit traffic on all 24 interfaces. The modular uplink slot accepts optional uplink modules for aggregation without reducing primary port throughput. Thermal management maintains stable operation during extended periods of maximum PoE and data throughput. The chassis stays within design limits when all ports negotiate 1000Base-T simultaneously.

Questions about this item

How do I install the EX4300-24P in a rack and what step is often missed?

Mount the 1U chassis using the supplied brackets, then insert an uplink module into the dedicated slot before powering on; the switch has no fixed uplinks without it.

Which component will need replacement first during long-term operation?

The 715 W AC power supply delivers 565 W for PoE+; plan to replace the PSU when fan noise rises or PoE budget drops below 565 W.

What limit appears first when all 24 ports run PoE+ at full load continuously?

The 565 W PoE+ budget caps total powered-device draw; you cannot exceed 565 W across the 24 ports even though the PSU is rated 715 W.
