ARUBA Instant On 1930 48G 4SFP+ Class 4 PoE 370W - Switch

The Aruba Instant On 1930 48G 4SFP+ Class 4 PoE 370W switch (S5E30A#ABB) is an unmanaged, plug-and-play device designed to expand wired network capacity. It provides 48 Gigabit Ethernet RJ-45 ports and four dedicated SFP+ slots for 10 Gbit/s data transfer. This configuration is suitable for high-density environments where many endpoints require reliable physical connections. The switch features Power over Ethernet (PoE) functionality, delivering a 370 W total power budget directly over standard network cabling. This allows devices such as IP cameras or wireless access points to draw power without needing adjacent electrical outlets. This 48-port model requires no initial configuration, ensuring straightforward installation.

Housed in a 1U rack-mountable chassis, the device fits into standard server cabinets. It measures 442.5 x 282.4 x 43.9 mm and weighs 3130 g, a standard footprint for IT enclosures. The fanless design ensures silent operation, even under continuous load, making the hardware suitable for noise-sensitive locations. A physical reset button is accessible on the exterior to restore factory settings if troubleshooting is required. An internal 800 MHz processor paired with 512 MB of SDRAM maintains stable data handling during periods of peak usage.

• 176 Gbit/s switching capacity for non-blocking throughput across all connections.
• 130.95 Mpps forwarding rate for efficient packet processing during heavy network traffic.
• 16,000-entry MAC address table to accommodate numerous devices within local area networks.
• 9216-byte jumbo frame support to improve data transfer efficiency for large file backups and server communications.
• 1.2 µs latency on 10 Gbps uplinks to minimise delay for time-critical data routing.
• 1.5 MB packet buffer memory to prevent dropped frames during sudden bursts of network activity.
• Firmware-upgradeable architecture to allow for future operational updates.
