Description

The HPE FlexNetwork 5130 EI is a 1U Layer 2/Layer 3 managed Gigabit Ethernet access switch built for network edge access and server connectivity in small data centres. It runs the Comware operating system and can be stacked with other units using Intelligent Resilient Framework (IRF), which presents several switches as one logical device.

The JG939A provides 48 autosensing 10/100/1000 RJ-45 ports with no PoE. Uplink and stacking connectivity comes from 2 fixed SFP+ ports (1G/10G) and 2 RJ-45 1/10GBASE-T ports, plus an RJ-45 serial console port. Switching capacity is 176 Gbps with forwarding of up to 130.9 Mpps, a 16,384-entry MAC address table, 1.5 MB packet buffer and 512 MB flash. Layer 3 support covers static routing and RIP for IPv4 and IPv6. Latency is under 5 microseconds at 1G and under 3 microseconds at 10G.

The SFP+ ports accept the genuine HPE X130 10G SFP+ SR (JD092B) and LR (JD094B) transceivers and X240 10G DAC cables (JD095C, JD096C, JD097C, JG081C), as well as a range of 1G SFPs including JD118B, JD119B and JD089B. It includes an internal AC power supply and mounts in a standard 19-inch rack. Optional external redundant power is available through the HPE RPS 800 (JD183A) or RPS1600 (JG136A with JG137A).

FAQs

Q: Does this switch provide PoE?
A: No. The JG939A is a non-PoE model, so PoE devices such as access points or phones need a separate PoE source.

Q: Does it need a separate licence for its features?
A: No separate licence is required. The Comware feature set, including static and RIP routing and IRF stacking, is built in.

Q: Which optics and cables work in the SFP+ ports?
A: The SFP+ ports take the HPE X130 10G SFP+ SR (JD092B) and LR (JD094B) transceivers and X240 10G DAC cables (JD095C, JD096C, JD097C, JG081C). 1G SFPs such as JD118B (SX), JD119B (LX) and JD089B (RJ45 T) are also supported.

Q: Can it be powered redundantly?
A: Yes. It has an internal power supply and can use an external HPE RPS 800 (JD183A) or RPS1600 (JG136A with JG137A) for redundant power.

Q: How are the two 10GBASE-T ports used?
A: The two RJ-45 1/10GBASE-T ports can serve as high-speed uplinks or as IRF stacking links, alongside the two SFP+ ports.
