Managed 24-port SFP+ switch

The HPE Aruba 3810M JL430A is a rackmount managed switch with 24 fixed SFP+ ports operating at 1000 or 10000 Mbps. It is designed for network administrators who need Layer 2 and Layer 3 capabilities with MACSec support on every port. Two open I/O module slots allow optional 40 GbE or Smart Rate expansion. This model suits environments that require a fixed 24-port 10G fibre uplinks configuration.

Thermals noise and 250W power supply

The unit ships with a 250W internal power supply operating on 100-240V AC. Power draw varies depending on installed modules and port utilisation. The 1U rackmount chassis uses internal fans for cooling; acoustic output will reflect the loaded port count and module choice. No external power adapter is required for the base configuration.

Dual ARM Cortex A9 and 13.5MB buffer

A dual-core ARM Cortex A9 processor at 1 GHz with 2GB DDR3 SDRAM drives the switching engine. The 13.5MB internal packet buffer helps absorb burst traffic at line rate. Latency measures below 2.8 µs at 1 Gbps and below 1.8 µs at 10 Gbps. Throughput reaches up to 190.5 Mpps with a 320 Gbps switching capacity.

Questions about this item

How do I install the JL430A in a rack and which step is often missed?

Mount the 1.73-inch high chassis in a standard 19-inch rack, connect the 100-240V AC cord, then insert SFP+ transceivers into the 24 ports; the step often missed is configuring each port for MACSec before linking devices.

What maintenance or replacement will the JL430A need over time?

The fixed 250W AC supply is not hot-swappable, so plan for a cold-swap replacement if it fails; internal fans are also fixed and should be kept clear of dust to avoid thermal throttling.

Which limit appears first when the JL430A runs at full load continuously?

The 13.5MB internal buffer fills before the 320 Gbps switching capacity is reached, so sustained line-rate traffic on all 24 SFP+ ports will hit buffering limits first.
