C9300-48P-A Description
The C9300-48P-A is a Cisco Catalyst 9300 Series stackable access switch with 48 10/100/1000 Mbps PoE+ ports, modular uplinks, and Network Advantage entitlement built into the hardware. It runs the default PWR-C1-715WAC-P supply for a 437W PoE budget, StackWise-480 stacking at up to 480 Gbps per stack, and Cisco StackPower support for shared redundancy across stack members. The Network Advantage tier on this PID unlocks advanced routing scale, network segmentation (VXLAN, LISP, Cisco TrustSec, MPLS), automation interfaces such as NETCONF and RESTCONF, and MACsec-256, making it the campus access switch for wiring closets that need both full PoE+ endpoint power and Layer 3 or segmentation features beyond a Layer 2-only access role.

Product Performance
Key Features
The 437W default PoE budget on the 715W supply is enough to power a full 48-port closet of PoE+ access points, cameras, and desk phones without ordering a second power supply for a typical deployment.
Network Advantage on this PID enables VRF, VXLAN, LISP, and Cisco TrustSec segmentation plus NETCONF/RESTCONF/YANG automation, which matters for access switches that must participate in software-defined segmentation rather than plain Layer 2 forwarding.
Up to 8 units stack into a single 480 Gbps logical switch, letting a wiring closet grow port count without adding separate management points or uplink pairs.
The modular uplink slot accepts field-replaceable network modules such as the C9300-NM-8X, so uplink speed can move from 1G/10G toward 25G later without replacing the switch chassis.
StackPower lets stacked C9300-48P-A units share power across the ring, which can offset a PoE+ closet’s peak load without dedicating a second internal supply to every member.
Network Advantage raises link encryption from MACsec-128 to MACsec-256, relevant where the access switch uplink or downlink must meet a higher encryption-strength policy than Essentials supports.
Application Scenarios
Deployed as the access layer in a wiring closet where VRF or VXLAN-based segmentation separates voice, IoT, and data VLANs across departments, using the Network Advantage entitlement built into this PID.
Positioned to power a full floor of PoE+ access points, IP phones, and PoE cameras from the 437W default budget while forwarding traffic upstream through the modular uplink slot.
Used as a stack member in an SD-Access or NETCONF/RESTCONF-managed campus fabric, where the Advantage-tier automation interfaces and MACsec-256 link encryption are part of the design requirement.

- C9300-48P-A and C9300-48T-A sit on the same 48-port modular-uplink chassis, but C9300-48T-A ships with the smaller 350W supply and carries no PoE capability at all, so it only fits a deployment with zero PoE endpoints on that closet; any PoE+ requirement moves the order back to C9300-48P-A.
- Against C9300-48H-A, the tradeoff is PoE headroom versus cost and default power draw: C9300-48H-A’s 1100W default supply provides an 822W Cisco UPOE+ budget for higher-wattage endpoints such as PTZ cameras or Wi-Fi 6E access points, while C9300-48P-A’s 437W PoE+ budget covers standard access points, desk phones, and PoE+ cameras at a lower default power supply cost.
- All three PIDs share the same 256 Gbps switching bandwidth and StackWise-480 stacking, so the decision between them is driven entirely by port power requirements, not switching or stacking capacity.
- Ordering priority for this comparison set: confirm whether any port on the closet needs PoE at all (if not, C9300-48T-A is the fit), then confirm whether standard PoE+ (30W-class) or Cisco UPOE+ (60W/90W-class) endpoints are planned before choosing between C9300-48P-A and C9300-48H-A.
Selection Guide
1. Segmentation and Automation Set the Advantage Floor
C9300-48P-A carries Network Advantage, which adds VXLAN/LISP/TrustSec segmentation, full automation (NETCONF/RESTCONF/YANG), and MACsec-256 over the C9300-48P-E’s Network Essentials; a closet doing pure Layer 2 access switching without segmentation or automation requirements can move to the -E variant and lower the license cost on identical hardware.
2. 437W PoE+ Ceiling Points to the UPOE+ Alternative
The 437W default PoE+ budget on this PID covers standard access points and IP phones, but a deployment planning Cisco UPOE or UPOE+ class endpoints (60W-90W per port) needs to move up to C9300-48H-A or C9300-24H-A instead, since C9300-48P-A’s port-level PoE+ output is not rated for that draw even with a larger secondary supply.
3. Second Supply Only for Budget Expansion, Not Redundancy Alone
Adding a second PWR-C1-1100WAC-P or PWR-C1-1900WAC-P supply raises the available PoE budget toward 1440W, so a design that needs more than 437W of PoE headroom should plan for the second supply slot at order time rather than assuming the default 715W supply alone will scale.
4. Subscription Tier Must Match Network Advantage
Because this PID’s Network Stack license is Network Advantage, the paired Cisco Catalyst or Cisco DNA software subscription ordered alongside it must also be Advantage tier on new purchase; ordering an Essentials-tier subscription against this hardware is only valid at renewal, not on a first order.

Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Network license match |
Confirm the Cisco Catalyst or Cisco DNA subscription ordered is Advantage tier on a new purchase. |
An Essentials-tier subscription paired with this Advantage hardware PID is only valid at renewal, not new order. |
|
Second power supply |
Confirm whether a second PWR-C1-1100WAC-P or PWR-C1-1900WAC-P is needed before the PoE load exceeds 437W. |
Ordering without the second supply leaves no path to expand PoE budget without a later add-order. |
|
Network module slot |
Confirm whether a C9300-NM-8X or other module is needed at order time, or order C9300-NM-BLANK for the empty slot. |
An empty uplink slot without a blank module affects airflow and is flagged during install. |
|
Smart Account binding |
Confirm the target Smart Account and Virtual Account before the order is placed. |
Catalyst 9300 SKUs are Smart SKUs; a license tied to the wrong account can stall activation. |
|
Stacking cable length |
Confirm StackWise cable length (0.5m/1m/3m) matches the physical rack layout if stacking multiple units. |
The wrong cable length can leave stack members unable to physically reach each other in the rack. |
