Cisco C9300-48P-A Switch
The Cisco Catalyst C9300-48P-A is a 48-port PoE+ Layer 3 managed switch with modular uplinks. It supports StackWise-480 stacking and 437W of PoE, with Network Advantage.
Overview
The Cisco Catalyst 9300 Series is Cisco's lead stackable enterprise access platform in the Catalyst 9000 family, built on the UADP 2.0 ASIC for investment protection and high-density stacking. The modular-uplink C9300 takes a field-installable network module for 1G, multigigabit, 10G, 25G, or 40G uplinks, and Cisco positions it as the successor to the end-of-sale Catalyst 3850. The C9300-48P-A is the 48-port PoE+ configuration at the Network Advantage tier, which is what separates it from the otherwise-identical Network Essentials C9300-48P-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 C9300-48P-A is a Layer 3 managed 1U rackmount access switch with 48 Gigabit Ethernet PoE+ ports and a modular uplink slot, running Cisco IOS XE with the perpetual Network Advantage license. Switching capacity is 256 Gbps and forwarding rate is 190.47 Mpps. All 48 access ports deliver PoE+ at up to 30 W per port; the PoE budget is 437 W with the default 715 W power supply and scales to 1440 W with dual power supplies. It supports Cisco StackWise-480 data stacking of up to eight members at 480 Gbps, plus Cisco StackPower. It powers wireless access points, IP phones, and IP cameras in campus and branch access networks.

Best For
The C9300-48P-A suits high-density enterprise campus and branch access that powers wireless access points, IP phones, and IP cameras while serving desktops and printers, with StackWise-480 stacking. How many devices it powers at once depends on each powered device's power draw and the installed power supplies, so size the PoE budget against the real load. The Network Advantage license fits sites running full dynamic routing, BGP, or SGT-based segmentation.
Not suitable if:
- you need UPOE at 60 W per port, since these ports deliver PoE+ at up to 30 W; the C9300-48U-A provides UPOE
- you need multigigabit (mGig) access ports, since this model has standard Gigabit ports; the C9300-48UXM provides mGig
- you want fixed built-in uplinks rather than a separately ordered network module, in which case the fixed-uplink C9300L fits better
- you only need basic Layer 2 switching, since the base Network Essentials tier would be sufficient

Part Number Decode
- C9300 — C9300 is the platform prefix, identifying the modular-uplink Cisco Catalyst 9300 Series.
- 48 — 48 is the port count, indicating 48 access ports.
- P — P is the port-type marker, indicating PoE+ Gigabit ports at up to 30 W.
- A — A is the license suffix for the perpetual Network Advantage tier.
FAQ
How much PoE power does the Cisco Catalyst C9300-48P-A provide?
The Cisco Catalyst C9300-48P-A delivers PoE+ at up to 30 W per port on all 48 Gigabit Ethernet access ports. With the default 715 W power supply the PoE budget is 437 W, and dual power supplies scale it to 1440 W, which is enough for all 48 ports to draw the full 30 W at once (48 x 30 W = 1440 W). Reaching the full 1440 W uses a 1100 W secondary supply rather than a second 715 W, and the budget determines how many devices draw full power simultaneously.
What uplink options does the C9300-48P-A support?
The C9300-48P-A has a modular uplink slot rather than fixed uplink ports. It accepts a Cisco Catalyst 9300 Series network module, with options spanning 4x 1G, 4x multigigabit, 8x 10G, 2x 25G, and 2x 40G; Catalyst 3850 network modules are also compatible. 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 C9300-48P-A switches can you stack?
The C9300-48P-A supports Cisco StackWise-480 data stacking of up to eight members at 480 Gbps of stack bandwidth, and Cisco StackPower for shared power and power redundancy across the stack. It stacks with other C9300 models, including mixed stacks with C9300X, and does not stack with C9300L, Catalyst 9200, or other series. StackWise and StackPower cables are ordered separately.
What is the difference between the C9300-48P-A and the C9300-48U-A?
Both are 48-port modular-uplink switches at the Network Advantage tier, and they differ in PoE class. The 48P-A delivers PoE+ at up to 30 W per port, with a budget up to 1440 W. The 48U-A delivers Cisco UPOE at up to 60 W per port, with a budget up to 1800 W, for higher-power endpoints. Choose the 48U when endpoints need more than 30 W per port.
What is the difference between the C9300-48P-A and the C9300-48P-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 is enabled by the term-based Cisco Catalyst subscription rather than the perpetual tier.
Does the C9300-48P-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 9300 replace an older switch?
Yes. Cisco's migration guidance positions the Catalyst 9300 as the successor to the end-of-sale Catalyst 3850. Migrating from a 3850 to the C9300-48P-A moves the access layer to Cisco IOS XE, StackWise-480 stacking, and StackPower, and existing Catalyst 3850 network modules remain compatible with the 9300.
Is the C9300-48P-A still current, and where is its lifecycle status published?
Network Devices Inc. sells the C9300-48P-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 C9300-48P-A sold in, and what warranty applies?
The C9300-48P-A is sold new and factory-sealed. It is covered by a Network Devices Inc. one-year warranty and a 30-day return policy.
