Silver 1U desktop switch with 24 Ethernet ports and SFP cages

Extreme

Extreme B5K125-24P2 24-port GbE 2-port 10GbE managed network switch

SKU CH-0WZC-Y9GB6 MPN B5K125-24P2

Managed 24-port Gigabit switch with two 10 Gigabit SFP+ uplinks and PoE support

  • 24 GbE ports connect workstations and printers
  • Two SFP+ uplinks carry 10 GbE traffic
  • PoE powers phones and cameras over cable
  • Layer 3 routing protocols direct network traffic
  • 103 W draw keeps electricity cost low

24-port GbE switch for managed networks

The Extreme B5K125-24P2 provides 24 copper ports at 10/100/1000 speeds plus two SFP+ uplink ports for 10 GbE fibre connections. It is built for network administrators who need Layer 2 and Layer 3 management in a 1U desktop enclosure. The switch supports PoE on the copper ports to power access points or IP phones directly.

PoE and dual SFP+ uplinks change deployment options

Power over Ethernet removes the need for separate injectors when connecting wireless APs, VoIP handsets or cameras. The two shared SFP slots and two dedicated SFP+ ports allow a mix of 1 GbE and 10 GbE fibre uplinks without using copper ports. Remote management via SNMP v3, SSH-2, HTTP and Telnet lets operators configure VLANs, routing and authentication from anywhere.

103 W power draw decides rack budget

The unit draws 103 W at nominal AC 120/230 V across 50-60 Hz, a figure that determines how many switches fit a single PDU or UPS circuit. Buyers who need higher PoE budgets per port or redundant power supplies should look elsewhere. The fixed 1U desktop form factor also rules out chassis-based blade installations.

Questions about this item

What maintenance will the PoE power supply need over time?

The unit draws 103 W at AC 120/230 V, 50-60 Hz; keep vents clear and verify fan operation periodically.

Which limit appears first when all 24 ports run at 1000 Mbps continuously?

The 103 W power budget caps total PoE output before port throughput saturates.

How much heat and noise should I expect from the 1U desktop enclosure running all day?

At 103 W draw the chassis warms noticeably; the internal fan runs continuously in the 1U desktop form factor.
