24-port Fast Ethernet switch for access-layer

The HPE 3100-24 provides twenty-four 10/100 Mbps downlink ports and two Gigabit Ethernet uplink slots in a rack-mountable Layer 2 chassis. It is designed for organisations that need affordable 100 Mbps-to-desktop connectivity in enterprise, metropolitan or industrial networks. Stackable architecture allows multiple units to be managed as a single logical device.

Sustained-load behaviour with link aggregation

Under continuous traffic the switch forwards at wire speed across all Fast Ethernet ports while the dual Gigabit uplinks handle aggregated upstream flows. Link aggregation groups combine physical links to increase usable bandwidth and maintain connectivity if a single member fails. The Layer 2 engine processes forwarding tables without blocking during prolonged peak utilisation.

Uplink flexibility decides fit

The two 1000Base-X expansion slots determine whether the unit matches a specific backbone design; each accepts a compatible Gigabit transceiver for fibre or copper uplink media. Buyers who require more than two uplinks or native 10 GbE interfaces will need a different platform.

Questions about this item

How much power does the 3100-24 draw when all 24 ports run at 100 Mbps all day?

The switch runs from an internal power supply and weighs 6.61 lb in its rack-mountable chassis; no separate power-consumption figure is published.

Which cables and rack hardware do I need before the 3100-24 will pass traffic?

The box includes mounting hardware; you supply 10/100Base-T patch cables for the 24 Fast Ethernet ports and 1000Base-X optics or copper modules for the two Gigabit uplink slots.

Will the 3100-24 trunk cleanly to my older 10 Mbps hubs over the Fast Ethernet downlinks?

Yes, the 24 downlink ports negotiate 10 or 100 Mbps, so legacy 10 Mbps gear connects directly while the two Gigabit uplinks aggregate toward the core.
