Can C9300-48UXM-A be stacked?

Yes, up to eight switches join a StackWise-480 stack, which raises switching capacity from 580 Gbps standalone to 1060 Gbps. StackPower is supported, so members can pool their power supplies. The default order also includes a 50 cm StackWise cable, which C9300-STACK-NONE removes.

How many switches can share power with C9300-48UXM-A in one StackPower ring?

Up to four switches share power in one StackPower ring, with 1+N redundancy for inline power. An XPS 2200 expandable power system extends the pool to eight members. C9300-48UXM-A uses CAB-SPWR-30CM or CAB-SPWR-150CM cables between members. StackPower works because this switch has a modular uplink slot, and fixed-uplink C9300L switches cannot join a power stack.

Which high-availability features does Network Advantage add on C9300-48UXM-A?

Network Advantage on C9300-48UXM-A adds NSF, GIR and xFSU for high availability, which Network Essentials does not include. It also adds EIGRP, HSRP, IS-IS, LISP and the NETCONF, RESTCONF, YANG and PnP or ZTP automation interfaces. These items come with the Advantage subscription term ordered with the switch, such as C9300-DNX-A-48-3Y.

Does C9300-48UXM-A keep UPOE devices powered through a reload?

Yes for soft reloads. Perpetual PoE keeps endpoints powered on C9300-48UXM-A during an upgrade, crash or manual reboot, and across stacks. It does not cover power loss, front-end processor removal or hibernation. Fast PoE restores power to the device in under 30 seconds from stored power and needs the perpetual-poe-ha setting on the port.

Which cable grade does C9300-48UXM-A need for 10G on its 12 Multigigabit ports?

Use Cat6 for 10G up to 55 m or Cat6A for 10G up to 100 m. Cat5e carries 100M to 2.5G, which is enough for the other 36 ports of C9300-48UXM-A. The 12 Multigigabit ports also run 5G, and every port delivers up to 60W UPOE.

Can C9300-48UXM-A take PWR-C1-1900WAC-P as a second supply?

Yes. PWR-C1-1900WAC-P is listed as a secondary supply across the Catalyst 9300 range and mixes with the other 9300 supplies. It outputs 1500W at 115V and 1900W at 230V and uses its own power cord. With the default PWR-C1-1100WAC-P as primary it brings the PoE budget to 2390W.

Is ThousandEyes included with the subscription for C9300-48UXM-A?

Yes. The ThousandEyes Network and Application Synthetics license, TE-EMBEDDED-T, is included by default with a 3, 5 or 7-year Cisco Catalyst or Cisco DNA Advantage subscription on Catalyst 9300 switches. It runs for the same term as the subscription. Essentials subscriptions do not include it, so the Advantage tier of C9300-48UXM-A qualifies.

Do Catalyst 9300X network modules fit the uplink slot of C9300-48UXM-A?

No. Catalyst 9300X network modules work only in Catalyst 9300X switches. The slot of C9300-48UXM-A takes the non-X Catalyst 9300 network modules, and Catalyst 3850 network modules also work in Catalyst 9300 non-X switches. Install C9300-NM-8X, C9300-NM-2Q or another listed 9300 module, or leave a blank module in the slot. The switch runs only with a module or blank installed.

Which StackWise speed applies when C9300-48UXM-A stacks with Catalyst 9300X switches?

A mixed stack runs StackWise-480 for the C9300-48UXM-A members. Catalyst 9300X switches support StackWise-1T at 1 Tbps, but that speed does not apply to the 9300 members of the stack. Plan the cables as STACK-T1-50CM, STACK-T1-1M or STACK-T1-3M for the 9300 members. Each stack member needs its own cable, so count the links before ordering spares.

C9300-48UXM-A Description

The C9300-48UXM-A 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 -A suffix carries Network Advantage, which includes OSPF without a route limit, VRF, VXLAN and Cisco TrustSec.

Key Features

Mixed 2.5G And 10G Access

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.

490W Default PoE Budget

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.

Cisco UPOE Across All 48 Ports

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.

Modular Uplink Slot

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 And StackPower

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.

Network Advantage Feature Set

The built-in Network Advantage license adds OSPF without a route limit, BGP, VRF, VXLAN, MPLS, Cisco TrustSec and MACsec-256 to the Network Essentials base.

Application Scenarios

Mixed-Speed Access Closet

In a wiring closet where most drops serve desktops and cameras at 2.5G, the twelve 10G Multigigabit ports connect higher-speed access points or edge appliances to the same switch.

Segmented Campus Edge

A campus building that separates tenants or departments can use Network Advantage VRF and VXLAN support at the access layer, so segmentation starts at the closet instead of the distribution switch.

UPOE Endpoint Rollout

Access points, IP phones and IoT devices that need Cisco UPOE power above standard PoE+ draw from the 490W default budget of a single supply, or from a stack that pools power with StackPower.

C9300-48UXM-A has 36 ports at 2.5G and 12 at 10G with a 490W default PoE budget, whereas C9300-48UN-A runs all 48 ports at 5G with 645W, which suits closets where every access point or endpoint link is 5G. Closets that need 10G on every port move to C9300-24UX-A, which has 24 ports and a 560W default budget. Network Advantage adds unlimited OSPF scale, VRF, VXLAN and Cisco TrustSec over Network Essentials; where a site needs none of these, the same hardware ships as C9300-48UXM-E. Cisco lists no Advantage-to-Essentials downgrade PID, so the tier is chosen on the switch order.

PoE Power Planning

Planning Item	Value or Check
PoE standard	Cisco UPOE
Default power supply	PWR-C1-1100WAC-P (1100W AC)
Default PoE budget	490W with the single default supply
Maximum PoE budget	Up to 2390W with an added 1900W second supply; upgrading the primary supply to 1900W raises the budget to 1290W-2880W depending on configuration
Second supply requirement	Confirm endpoint power draw against the 490W default budget before assuming a second supply is unnecessary
StackPower option	Available on StackWise-480 stacks to share power headroom across member switches

Ordering Checklist

Subscription term: Order a 48-port Advantage term: C9300-DNX-A-48-3Y, -5Y or -7Y. Advantage is the configurator default (5 years); the term can be changed to 3 or 7 years but must stay Advantage.
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.

Questions & Answers

Can C9300-48UXM-A be stacked?
Yes, up to eight switches join a StackWise-480 stack, which raises switching capacity from 580 Gbps standalone to 1060 Gbps. StackPower is supported, so members can pool their power supplies. The default order also includes a 50 cm StackWise cable, which C9300-STACK-NONE removes.
What does Network Advantage on C9300-48UXM-A include?
Network Advantage on C9300-48UXM-A adds OSPF without a route limit, BGP, VRF, VXLAN, MPLS, Cisco TrustSec and MACsec-256 to the Network Essentials base. The subscription term must be an Advantage term, such as C9300-DNX-A-48-3Y.
How many switches can share power with C9300-48UXM-A in one StackPower ring?
Up to four switches share power in one StackPower ring, with 1+N redundancy for inline power. An XPS 2200 expandable power system extends the pool to eight members. C9300-48UXM-A uses CAB-SPWR-30CM or CAB-SPWR-150CM cables between members. StackPower works because this switch has a modular uplink slot, and fixed-uplink C9300L switches cannot join a power stack.
Which high-availability features does Network Advantage add on C9300-48UXM-A?
Network Advantage on C9300-48UXM-A adds NSF, GIR and xFSU for high availability, which Network Essentials does not include. It also adds EIGRP, HSRP, IS-IS, LISP and the NETCONF, RESTCONF, YANG and PnP or ZTP automation interfaces. These items come with the Advantage subscription term ordered with the switch, such as C9300-DNX-A-48-3Y.
Does C9300-48UXM-A keep UPOE devices powered through a reload?
Yes for soft reloads. Perpetual PoE keeps endpoints powered on C9300-48UXM-A during an upgrade, crash or manual reboot, and across stacks. It does not cover power loss, front-end processor removal or hibernation. Fast PoE restores power to the device in under 30 seconds from stored power and needs the perpetual-poe-ha setting on the port.
Which cable grade does C9300-48UXM-A need for 10G on its 12 Multigigabit ports?
Use Cat6 for 10G up to 55 m or Cat6A for 10G up to 100 m. Cat5e carries 100M to 2.5G, which is enough for the other 36 ports of C9300-48UXM-A. The 12 Multigigabit ports also run 5G, and every port delivers up to 60W UPOE.
Can C9300-48UXM-A take PWR-C1-1900WAC-P as a second supply?
Yes. PWR-C1-1900WAC-P is listed as a secondary supply across the Catalyst 9300 range and mixes with the other 9300 supplies. It outputs 1500W at 115V and 1900W at 230V and uses its own power cord. With the default PWR-C1-1100WAC-P as primary it brings the PoE budget to 2390W.
Is ThousandEyes included with the subscription for C9300-48UXM-A?
Yes. The ThousandEyes Network and Application Synthetics license, TE-EMBEDDED-T, is included by default with a 3, 5 or 7-year Cisco Catalyst or Cisco DNA Advantage subscription on Catalyst 9300 switches. It runs for the same term as the subscription. Essentials subscriptions do not include it, so the Advantage tier of C9300-48UXM-A qualifies.
Do Catalyst 9300X network modules fit the uplink slot of C9300-48UXM-A?
No. Catalyst 9300X network modules work only in Catalyst 9300X switches. The slot of C9300-48UXM-A takes the non-X Catalyst 9300 network modules, and Catalyst 3850 network modules also work in Catalyst 9300 non-X switches. Install C9300-NM-8X, C9300-NM-2Q or another listed 9300 module, or leave a blank module in the slot. The switch runs only with a module or blank installed.
Which StackWise speed applies when C9300-48UXM-A stacks with Catalyst 9300X switches?
A mixed stack runs StackWise-480 for the C9300-48UXM-A members. Catalyst 9300X switches support StackWise-1T at 1 Tbps, but that speed does not apply to the 9300 members of the stack. Plan the cables as STACK-T1-50CM, STACK-T1-1M or STACK-T1-3M for the 9300 members. Each stack member needs its own cable, so count the links before ordering spares.
