Cisco C9300-48UXM-E Switch

Yes. The Cisco Catalyst C9300-48UXM-E delivers Cisco UPOE (IEEE 802.3bt Type 3) on all 48 multigigabit access ports at up to 60 W per port, which lets it power high-draw devices such as Wi-Fi 6 wireless access points, pan-tilt-zoom IP cameras, IP phones, and building-IoT endpoints. The system PoE power budget is 490 W on the default 1100 W power supply, expandable to 2880 W with dual 1900 W power supplies.

The Cisco Catalyst C9300-48UXM-E has a mixed multigigabit port layout across its 48 access ports: 12 ports support speeds up to 10G and the remaining 36 ports support speeds up to 2.5G, all over existing copper cabling. The 12 higher-speed ports suit the most demanding Wi-Fi 6 access points and multigigabit uplink devices, while the 2.5 Gbps ports serve mainstream multigigabit endpoints. This mixed layout distinguishes it from the C9300-48UN, whose 48 ports are uniformly rated up to 5G.

The Cisco Catalyst C9300-48UXM-E has a modular uplink slot rather than fixed uplink ports. It accepts a field-installable Cisco Catalyst 9300 Series network module, with options spanning 1G, multigigabit, 10G, 25G, and 40G uplinks. The network module is ordered separately. Specific transceiver compatibility should be verified against the manufacturer's transceiver compatibility matrix at tmgmatrix.cisco.com. Transceivers are sold separately.

The Cisco Catalyst C9300-48UXM-E supports Cisco StackWise-480 data stacking of up to eight members at 480 Gbps of stack bandwidth, using StackWise stacking cables. As a modular C9300 it also supports Cisco StackPower, which pools the power supplies across the stack for power redundancy and supplemental power; up to four switches can be combined in a StackPower stack, or up to eight with the XPS-2200 appliance. It stacks with other C9300 modular switches; the fixed-uplink C9300L uses StackWise-320 and does not support StackPower.

The two switches share identical hardware (48 Cisco UPOE multigigabit ports with 12 up to 10G and 36 up to 2.5G, a modular uplink slot, StackWise-480 stacking, and StackPower) and differ only in license tier. The C9300-48UXM-E ships with perpetual Network Essentials, which covers Layer 2 plus basic routed access. The C9300-48UXM-A ships with perpetual Network Advantage, which adds full OSPF, EIGRP, BGP, IS-IS, HSRP, VRF, VXLAN, LISP, and SGT segmentation.

No. The switch runs on its included perpetual base license indefinitely. Under Cisco's ordering model, new switch orders include a term-based Cisco DNA or Cisco Catalyst software subscription of the same tier as the network license; that subscription unlocks Cisco Catalyst Center and cloud-managed features. When the subscription term ends, the switch continues operating on the perpetual base license capabilities after a reload.

Yes. Cisco positions the Catalyst 9300 Series as the successor to the end-of-sale Catalyst 3850 Series access switches. Organizations migrating from the 3850 to the C9300-48UXM-E move to Cisco IOS XE and gain multigigabit access, StackWise-480 stacking, StackPower, SD-Access-capable hardware, and the Network Essentials routed-access feature set; existing Catalyst 3850 network modules remain compatible.

No. Cisco has not published an End-of-Sale or End-of-Life hardware notice for the Cisco Catalyst C9300-48UXM-E. Cisco's published end-of-life notices for the Catalyst 9300 Series to date cover specific IOS XE software releases and license offers, not the switch hardware, so the C9300-48UXM-E remains an actively available product.

The Cisco Catalyst C9300-48UXM-E is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
