C9300-48UXM-E Description
The C9300-48UXM-E is a Cisco Catalyst 9300 Series stackable access switch for wiring closets that mix 2.5G endpoints with a smaller group of 10G multigigabit devices. The switch has 36 100M/1G/2.5G ports and 12 Multigigabit ports up to 10G, all with Cisco UPOE, a 490W default PoE budget, a modular uplink slot and 580 Gbps of switching capacity. The -E suffix carries Network Essentials, which covers Layer 2 and OSPF routing up to 1,000 routes but not VRF or VXLAN.

Product Performance
Key Features
Thirty-six ports run 100M, 1G or 2.5G and twelve Multigigabit ports run up to 10G. Dense desktop and camera drops and a smaller group of 10G devices therefore share one chassis.
The default 1100W AC supply leaves 490W for powered devices. A 350W, 715W, 1100W or 1900W secondary supply raises that to 840W, 1205W, 1590W or 2390W.
Every port is a Cisco UPOE port, so Type 1, Type 2, Type 3 and UPOE devices drawing up to 60W can connect to any drop in the closet.
The slot takes C9300-NM-4G, C9300-NM-8X, C9300-NM-2Q, C9300-NM-2Y or C9300-NM-4M network modules, and the switch runs only with a network module or a blank module installed.
StackWise-480 provides 480 Gbps of stack bandwidth and raises switching capacity from 580 Gbps standalone to 1060 Gbps. StackPower pools the power supplies of the stack members.
The built-in Network Essentials license covers Layer 2, routed access with OSPF up to 1,000 routes, 802.1X and MACsec-128. Features such as VRF, VXLAN and MPLS are part of Network Advantage.
Application Scenarios
Most drops in a closet like this serve desktops and cameras at 2.5G, while the twelve 10G Multigigabit ports connect higher-speed access points on the same switch.
At a branch office, the switch powers phones and access points over UPOE and uses Network Essentials routed access to reach the site router.
Several of these switches can join one StackWise-480 stack in a large closet, with StackPower sharing power supplies across the members and the uplink module set per stack.

C9300-48UXM-E offers 36 ports at 2.5G and 12 at 10G with a 490W default PoE budget, while C9300-48UN-E gives all 48 ports 5G multigigabit and 645W, which fits closets where every access point or endpoint link runs at 5G. Closets that need 10G on every port, at 24 ports and 560W, take C9300-24UX-E. C9300-48UXM-E carries Network Essentials, which covers Layer 2 and OSPF up to 1,000 routes; VRF, VXLAN or unlimited OSPF scale calls for C9300-48UXM-A, or an installed switch can be upgraded later with a C9300-LIC= term (C9300-48-E-A-3, -5 or -7), which cannot be placed on the switch order.

Order Impact |
|---|---|---|
|
Default PoE budget |
C9300-48UXM-E is listed with 490W available PoE and PWR-C1-1100WAC-P as the default supply |
Size the powered endpoint plan against the base budget before assuming secondary power |
|
Secondary supply options |
With PWR-C1-1100WAC-P as primary, Cisco lists 840W with a 350W secondary, 1205W with a 715W secondary, 1590W with an 1100W secondary, and 2390W with a 1900W secondary |
Add the secondary supply that matches the UPOE endpoint load and redundancy target |
|
1900W upgrade path |
With PWR-C1-1900WAC-P as primary, Cisco lists 1290W available PoE before secondary power and up to 2880W with larger secondary supplies |
Use the upgrade path only when the power design requires the larger Cisco-listed budget |
|
StackPower support |
Catalyst 9300 modular-uplink switches support StackPower |
Include StackPower cabling only when shared power is part of the stack design |
Ordering Checklist
- Subscription term: Order a 48-port Essentials term: C9300-DNX-E-48-3Y, -5Y or -7Y. The configurator defaults to Cisco DNA Advantage for 5 years, so Essentials hardware needs its tier set by hand.
- Uplink module: C9300-NM-8X is selected by default; pick another C9300 network module or C9300-NM-NONE. The modular uplink slot ships with the default module unless it is changed or removed.
- Second power supply: A second supply identical to the primary is selected by default and C9300-SPS-NONE removes it. Without it the switch runs on one supply and the PoE budget is the single-supply default.
- Stack cables: A 50 cm StackWise cable (C9300-STACK-NONE removes it) and a 30 cm StackPower cable (C9300-SPWR-NONE removes it) are included by default. Stacks that span racks need longer cables, and stand-alone switches need neither.
- Power cords: Order two cords for the destination country. The configurator defaults to North America cords.
