Cisco C9300X-48TX-A Switch
The C9300X-48TX-A is a 48-port data-only Multigigabit 10G Layer 3 managed switch with modular uplinks to 100G. It supports StackWise-1T stacking, with Network Advantage.
Overview
The Cisco Catalyst 9300 Series is Cisco's lead stackable enterprise access platform in the Catalyst 9000 family. The C9300X is its high-performance member, built on the UADP 2.0sec ASIC, which adds 100G line-rate hardware IPsec (an HSEC license key is required to enable it), and Cisco positions it as a successor to the end-of-sale Catalyst 3850. The C9300X-48TX-A is the 48-port data-only 10G multigigabit configuration at the Network Advantage tier, giving every port up to 10G of copper throughput without PoE, and its tier separates it from the otherwise-identical Network Essentials C9300X-48TX-E. Network Advantage unlocks full dynamic routing and policy-based segmentation. Three field-replaceable fans and dual power supplies keep it serviceable in always-on deployments.
Technical Details
The Cisco Catalyst C9300X-48TX-A is a Layer 3 managed 1U rackmount access switch with 48 multigigabit data ports running at up to 10G and a modular uplink slot, running Cisco IOS XE with the perpetual Network Advantage license. Switching capacity is 1,760 Gbps and forwarding rate is 1309 Mpps. The access ports are data-only and carry no Power over Ethernet. It supports Cisco StackWise-1T data stacking of up to eight members at 1 Tbps, plus Cisco StackPower+. It connects high-throughput non-powered endpoints such as high-performance workstations and 10G-attached hosts in campus and branch networks.

Best For
The C9300X-48TX-A suits a high-throughput access or aggregation layer that connects non-powered endpoints needing up to 10G over copper, such as high-performance workstations and 10G-attached hosts, with StackWise-1T stacking and 100G-capable uplinks. It has no PoE, so it fits where power is delivered separately, and the Network Advantage license fits sites running full dynamic routing, BGP, or SGT-based segmentation.
Not suitable if:
- you need to power devices such as wireless access points, IP phones, or IP cameras, since this is a data-only switch with no Power over Ethernet; the C9300X-48HX provides UPOE+
- your endpoints are only 1G, since the 10G multigigabit capability would be underused
- you need fiber access ports, since these are copper multigigabit ports; the C9300X-24Y provides 25G SFP28 fiber
- you only need basic Layer 2 switching, since the base Network Essentials tier would be sufficient

Part Number Decode
- C9300X — C9300X is the platform prefix, identifying the high-performance modular-uplink Cisco Catalyst 9300 Series.
- 48 — 48 is the port count, indicating 48 access ports.
- TX — TX is the port-type marker, indicating data-only 10G multigigabit copper ports with no Power over Ethernet.
- A — A is the license suffix for the perpetual Network Advantage tier.
FAQ
Does the Cisco Catalyst C9300X-48TX-A support PoE?
No. The Cisco Catalyst C9300X-48TX-A is a data-only switch, and all 48 multigigabit access ports carry no Power over Ethernet. It cannot power devices such as wireless access points, IP phones, or IP cameras. If you need to power endpoints, the C9300X-48HX is the equivalent multigigabit model with Cisco UPOE+ at up to 90 W per port.
What uplink options does the C9300X-48TX-A support?
The C9300X-48TX-A has a modular uplink slot that takes a Cisco Catalyst 9300X network module, with options spanning 8x 10G, 8x 25G, 2x 100G, and 4x 100G, so uplinks can scale to 100G. 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.
How many C9300X-48TX-A switches can you stack?
The C9300X-48TX-A supports Cisco StackWise-1T data stacking of up to eight members at 1 Tbps of stack bandwidth, plus Cisco StackPower+ for shared power across the stack. It can also stack with modular Catalyst 9300 switches, in which case the data stack runs at the lower StackWise-480 speed. StackWise and StackPower cables are ordered separately.
What is the difference between the C9300X-48TX-A and the C9300X-48HX-A?
Both are 48-port 10G multigigabit switches on the C9300X platform at the Network Advantage tier, and they differ in PoE. The 48TX-A is data-only and carries no Power over Ethernet. The 48HX-A delivers Cisco UPOE+ at up to 90 W per port. Choose the 48TX for high-throughput hosts that are powered separately, and the 48HX to power access points, cameras, or phones.
What is the difference between the C9300X-48TX-A and the C9300X-48TX-E?
The two switches are identical hardware and differ only in license tier. The -E model ships with perpetual Network Essentials, which covers Layer 2 plus basic routed access such as static routing, RIP, EIGRP stub, OSPF for up to 1,000 routes, PBR, PIM stub multicast, and VRRP. The -A model ships with perpetual Network Advantage, which adds full OSPF, EIGRP, BGP, IS-IS, HSRP, VRF, VXLAN, LISP, and SGT segmentation. SD-Access and 100G IPsec (with an HSEC key) are enabled separately from the perpetual tier.
Does the C9300X-48TX-A require a subscription to operate?
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.
Does the Cisco Catalyst 9300X replace an older switch?
Yes. Cisco's migration guidance positions the Catalyst 9300X as a successor to the end-of-sale Catalyst 3850. Migrating to the C9300X-48TX-A moves the access layer to Cisco IOS XE, StackWise-1T stacking, 10G multigigabit copper, and 100G-capable uplinks with the Network Advantage feature set.
Is the C9300X-48TX-A still current, and where is its lifecycle status published?
Network Devices Inc. sells the C9300X-48TX-A as current, new, factory-sealed stock. Cisco publishes End-of-Sale and End-of-Life status for every Catalyst 9300 Series part number on its official End-of-Life and End-of-Sale Notices page for the series, which is the authoritative source for a specific SKU. Buyers standardizing on a platform for a multi-year refresh should confirm the current status there before ordering.
What condition is the C9300X-48TX-A sold in, and what warranty applies?
The C9300X-48TX-A is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
