48-port PoE Layer 3 switch

The Cisco C1300X-48P-4X is a rack-mount managed switch delivering 48 Gigabit Ethernet ports with full PoE support and four 10G SFP28 uplinks. It targets small to medium businesses and branch offices that need wire-speed Layer 3 routing plus a 740 W power budget for access points, cameras and VoIP phones.

Sustained load behaviour

A 3 MB packet buffer and 130.95 Mpps forwarding rate absorb traffic bursts without head-of-line blocking, while eight hardware queues with strict priority and weighted round-robin scheduling keep latency-sensitive flows stable under continuous load. The MAC table scales to 32,000 entries and jumbo frames up to 9,000 bytes reduce per-packet overhead during prolonged transfers.

740 W PoE budget constraint

The single figure that decides fit is the 740 W PoE budget spread across all 48 ports; deployments whose powered devices exceed that aggregate draw will need additional switches or mid-span injectors. Cross-family stacking is not supported, so future expansion must stay within the C1300X series.

Highlights

  • 48 PoE ports with 740 W budget power IP phones and cameras
  • Four 10 Gbps uplinks plus optional 25 G stacking links handle heavy traffic
  • Layer 3 routing supports 7168 IPv4 routes for network segmentation
  • Stack up to 8 units for 400 ports managed as one system
  • Browser-based dashboard with simple and advanced modes speeds configuration

Questions about this item

How much power does the C1300X-48P-4X draw when all 48 PoE ports are fully loaded at 740W?

The switch provides a 740W PoE budget across its 48 ports. Total system power draw will equal that budget plus the switch's own operating consumption, which varies with traffic load and ambient temperature.

Which SFP modules or cables must I already own to use the four 10G uplinks on this switch?

The four uplinks are SFP28 cages that accept 10G SFP+ transceivers or direct-attach cables. 25G modules are supported only when stacking switches together.

Will my existing Cat5e patch cables work at Gigabit speeds on the 48 RJ-45 ports of this switch?

Yes. The 48 downlink ports comply with IEEE 802.3ab 1000BASE-T, so Cat5e or better cabling will negotiate 1 Gbps full-duplex links.
