Power Supply System
AC Power Supply
The S310-24P4X supports one built-in AC PSU. The PSU powers both switch operations and PoE delivery to connected PDs. Available PSU options to match deployment PoE requirements:
- 740W PSU — up to 740 W total PoE budget (recommended for high-density PoE+ deployments)
- 370W PSU — up to 370 W total PoE budget
- 110W PSU — for limited PoE deployments with a small number of PDs
PoE Budget & Priority Management
PoE budget is shared dynamically across all 24 GE ports. The switch enforces per-port and aggregate PoE limits to prevent overloads:
- Max per-port PoE+: 30 W (IEEE 802.3at)
- Max aggregate budget: up to 740 W (with 740W PSU)
- Priority-based management — ports with the lowest configured priority are powered off first when the PoE budget is exceeded
- Per-port PoE enable/disable configurable via CLI, web GUI, or iMaster NCE-Campus
Heat Dissipation System
Front panel (port side) — Cold air inlet → Rear panel — Hot air outlet
Airflow Direction
Cold air is drawn in through the front panel (port side) and expelled as hot air from the rear panel. A built-in fan module with smart speed control automatically adjusts fan RPM based on real-time internal temperature sensor readings — balancing cooling performance with acoustic noise. Operating noise level: ≤ 42 dB(A) at 25°C ambient.
Installation Requirements
- Leave ≥ 10 cm clearance at the front and rear of the switch for airflow
- Leave ≥ 5 cm clearance on the left and right sides
- Do not obstruct front or rear ventilation panels with cables or objects
- Operating temperature: 0°C to +45°C (long-term)
- Operating humidity: 5%–95% RH, non-condensing
- Mount in a 19-inch rack using supplied rack-mount ears; ensure the rack cabinet has adequate airflow
