HPE

HPE FlexNetwork 5140 HI 1-slot L3 Managed 48x 10/100/1000 4x 10G SFP+ side-to-back airflow network switch

SKU CH-KKKQ-WTWJT

Layer 3 managed switch with 48 Gigabit ports, four 10G SFP+ uplinks and PoE+ in a side-to-back airflow chassis

  • 48 Gigabit ports connect many wired devices
  • 4 ten-gigabit SFP+ uplinks aggregate high-speed traffic
  • Layer 3 routing moves packets between subnets efficiently
  • Side-to-back airflow matches standard rack cooling designs

48-port Layer-3 switch with 10G uplinks

The HPE FlexNetwork 5140 HI is a managed, rack-mountable switch that delivers 48 copper ports at 10/100/1000 speeds plus four 10G SFP+ uplinks. It targets midsize campus or branch networks that need Layer-3 routing, PoE+ power delivery and side-to-back airflow in a single-slot chassis.

Sustained load behaviour

Under continuous traffic the side-to-back airflow design maintains stable operating temperatures across all 48 ports and four uplinks. The managed Layer-3 engine handles persistent routing tables and QoS policies without throughput degradation, while PoE+ budget remains available for attached devices during extended operation.

Highlights

  • 48 Gigabit ports connect many wired devices
  • 4 ten-gigabit SFP+ uplinks aggregate high-speed traffic
  • Layer 3 routing moves packets between subnets efficiently
  • Side-to-back airflow matches standard rack cooling designs

Questions about this item

How much heat and noise does the side-to-back airflow produce when the 48 PoE+ ports run all day?

The side-to-back airflow moves heat out the rear so the chassis stays cool even with 48 powered devices, and fan speed ramps only under heavy load keeping noise low in a rack.

Which SFP+ transceivers do I need to populate the four 10G uplinks?

Any standard 10 Gigabit SFP+ module — SR, LR or compatible third-party optics — will work in the four uplink cages.
