What is the switching latency and capacity?

The cut-through nonblocking architecture delivers ~1 microsecond latency for 10GbE traffic, with full wire-speed on all ports including 40GbE uplinks. Jumbo frames up to 10,000 bytes ensure high throughput for demanding datacenter applications, as specified in HPE technical docs.

Does it support Layer 3 features?

Yes, full L2/L3 capabilities include IPv6 support, FIP snooping, DCB, FCoE, TRILL, and advanced VLANs (MAC/protocol/subnet-based). IRF virtualization enables stacking for scalable management in enterprise networks, confirmed in HPE support documentation.

What power options are available?

Hot-plug redundant power supplies support AC 100-240V or DC -40 to -60V, with 200W idle power and max 887 BTU/hr heat dissipation. This design ensures high availability for mission-critical datacenter use, per HPE QuickSpecs.

Is it suitable for datacenter ToR deployment?

Optimized as a 1U rack-mountable ToR switch with high 10GbE port density and 40GbE uplinks, ideal for server access in large/medium datacenters handling virtualization and server-to-server traffic, as described in HPE FlexFabric series overview.

What management interfaces are provided?

Features 1 RJ-45 out-of-band management port alongside console and USB ports, with IRF for virtualizing up to stacks as a single logical switch. Supports Comware OS for comprehensive L2/L3 protocol handling in bulk deployments.

Product overview

The HPE FlexFabric 5900AF-48XG-4QSFP+ Switch (JC772A, SKU 5900AF-48XG-4QSFP+) is a high-performance Top-of-Rack (ToR) Ethernet switch from the HPE FlexFabric 5900 Series, designed for datacenter environments. It features 48 fixed 1000/10000 SFP+ ports and 4 QSFP+ 40 GbE ports, each configurable as 4x 10GbE using splitter cables. The switch employs a high-performance cut-through nonblocking architecture with low latency of approximately 1 microsecond for 10GbE traffic, supporting jumbo frames up to 10,000 bytes. Full Layer 2/Layer 3 features include IPv6, FIP snooping, DCB, FCoE, and TRILL. Management options comprise 1 RJ-45 out-of-band port, 1 RJ-45 console, and 1 USB 2.0 port, with IRF virtualization for simplified two-tier architectures. Power supplies are hot-plug redundant, supporting AC 100-240V or DC -40 to -60V, with idle power at 200W and max heat dissipation of 887 BTU/hr. This 1U rack-mountable switch excels in high-density server access and core layers for virtualized applications.
