Aruba CX 4100i 24-port PoE switch

The Aruba CX 4100i is a Layer 3 manageable Ethernet switch with twenty-four RJ-45 ports and four SFP+ uplink slots. It delivers 10/100/1000Base-T connectivity on copper and 10GBase-X on fibre uplinks. A single internal power supply provides a 240 W PoE budget across the RJ-45 ports.

Ideal for PoE edge deployments.

This switch suits networks that need to power access points, cameras or phones directly from the access layer. The four high-power PoE ports and twenty PoE+ ports cover typical endpoint mixes. Buyers who do not require PoE or who need higher port density at the aggregation layer should evaluate other platforms.

240 W PoE budget determines powered device count

The 240 W budget is the single figure that decides how many IEEE 802.3af, 802.3at or 802.3bt endpoints can operate simultaneously. Calculate the total draw of your powered devices against this limit before purchase.

Questions about this item

How do I install the CX 4100i switch and what step is often missed?

Mount the switch in a rack, connect the power supply, then plug devices into the 20 PoE+ and 4 Hi PoE RJ-45 ports; the step often missed is inserting SFP+ transceivers into the four uplink slots before cabling fibre uplinks.

What maintenance or replacement will the CX 4100i need later?

The single installed power supply is the only field-replaceable component; plan to swap it if it fails, and keep spare SFP+ modules on hand for the four uplink slots.

What limit appears first on the CX 4100i under sustained PoE load?

The 240 W PoE budget caps total powered-device draw; once connected devices exceed that budget, ports will disable PoE starting with the highest-numbered interfaces.
