Aruba HPE Networking Instant On 1940 - 48-port Smart-managed Layer 2+ PoE switch

The Aruba Instant On 1940 Smart-Managed PoE switch is a Layer 2+ device designed to expand wired network capacity. It provides 48 Gigabit/2.5G Ethernet ports for local hardware connections and supports data transfer rates of up to 10 Gbit/s. This model offers Power over Ethernet (PoE) across all 48 ports, with a total budget of 600 W, allowing the switch to power compatible network devices directly.

The 48-port switch measures 570 x 500.1 x 112 mm (W x D x H) and weighs 7400 g. It includes a 1250 MHz processor, 1024 MB of RAM, and 512 MB of flash memory. The switching capacity is 200 Gbit/s, with a forwarding throughput of 148.8 Mpps. Connectivity relies on copper Ethernet (RJ-45) with dedicated uplinks.

• 4 SFP module slots provide dedicated uplinks for high-speed fiber optic networking.
• 4 MB of packet buffer memory stores incoming data during traffic spikes to prevent packet loss.
• Auto-MDI/MDIX automatically configures port connections, removing the need for crossover cables.
• Jumbo frames support allows the transmission of larger data payloads to improve transfer efficiency.
• Switching latency is 0.75 µs on 10 Gbit/s connections and 2.7 µs on 1 Gbit/s links.
• Security protocols include TACACS+, AAA, and TPM 2.0 for authenticated network access control.
