Overview
About the S5E29A
The HPE Networking Instant On Switch 24p Gigabit 16p CL4 PoE 4p SFP 195W 1840 (S5E29A) is a 24-port smart-managed Layer 2 gigabit switch in which the first sixteen ports supply IEEE 802.3at Class 4 PoE within a 195 W budget. Ports 17 to 24 are standard copper, and four dedicated 1G SFP ports provide fibre uplinks.
The sixteen-of-twenty-four split is the practical shape for a floor: powered access points, cameras and phones on the PoE half, and desktops, printers and unpowered devices on the rest, all in one 1U unit. At 195 W the budget averages roughly 12 W across all sixteen powered ports, comfortably above the draw of a typical Wi-Fi access point or fixed dome camera.
Switching capacity is 56 Gbps with 41.66 Mpps forwarding, matching the non-PoE S5E28A, and latency improves to under 8.8 µs at 100 Mb and under 4.7 µs at 1000 Mb. Two fixed fans handle the PoE stage with left-to-right airflow, rated at 3.3 Bel sound power.

Frequently asked questions
How many ports on the S5E29A supply PoE?
Sixteen of the twenty-four access ports — ports 1 to 16 — supply IEEE 802.3at Class 4 PoE at up to 30 W each within a 195 W total budget. Ports 17 to 24 are standard copper with no power.
How many access points can the S5E29A power?
The 195 W budget averages about 12 W across all sixteen powered ports. Wi-Fi 6 access points typically draw well under 30 W, so a full complement of sixteen is realistic where per-device draw is modest; LLDP allocation grants each port only what it requests.
S5E29A or S5E31A — which PoE model do I need?
The S5E29A gives 16 PoE ports and 195 W across 24 access ports. The S5E31A gives 24 PoE ports and 370 W across 48 access ports. Choose by the number of powered drops and the total wattage the site requires.
Compare the S5E31AHow loud is the S5E29A?
HPE rates it at 3.3 Bel declared sound power and 21 dB mean bystander sound pressure, with two fixed non field-replaceable fans and left-to-right airflow.
Can PoE be switched off outside business hours?
Yes. PoE scheduling allows power delivery to be limited to a specific day and time of the week, and port scheduling allows up to three schedules per port to enable or disable the port or its PoE.
