C9300-48H-A Description
The C9300-48H-A is a Cisco Catalyst 9300 Series stackable access switch that packs 48 Cisco UPOE+ copper ports and an empty modular uplink bay onto the same standard-scale C9300 chassis, aimed at closets that need to power a large count of high-draw endpoints such as Wi-Fi 6E APs, PTZ cameras, and lighting controllers across a full floor rather than a single rack row. Cisco's Hardware Installation Guide documents an 822W PoE budget on the default PWR-C1-1100WAC-P supply, and the datasheet lists a design ceiling of 2880W once a second supply is installed, roughly a third more headroom than the 24-port C9300-24H-A reaches at 2160W. The switch runs 256 Gbps of switching capacity and a 190.48 Mpps forwarding rate, holds the Network Advantage perpetual license for unrestricted routing, VRF/VXLAN/LISP segmentation, and MACsec-256, and stacks up to 8 members over StackWise-480 with StackPower available to pool power headroom across the ring.

Key Features
Packing 48 Cisco UPOE+ ports and an 822W default PoE budget onto one chassis lets a single unit cover a full floor of high-draw endpoints that would otherwise need two 24-port UPOE+ switches, reducing the number of stack members a closet has to manage.
Cisco’s documented ceiling on this chassis reaches 2880W once a second supply is installed, about a third more than the 2160W ceiling on the 24-port C9300-24H-A, so a design already sizing dense high-draw deployments has more room to grow before hitting a design limit.
Because the uplink bay ships empty, the closet design can defer whether to run 10G SFP+ (C9300-NM-8X), 40G QSFP+ (C9300-NM-2Q), or 25G SFP28 (C9300-NM-2Y) until the distribution-layer speed is confirmed, instead of locking in a fixed uplink at time of switch order.
Network Advantage adds VRF, VXLAN, LISP, and Cisco TrustSec segmentation plus NETCONF/RESTCONF/YANG automation and MACsec-256 on top of the same hardware sold as C9300-48H-E, so a design that needs network segmentation or model-driven automation at this closet does not need a separate switch model.
StackPower lets up to 4 stack members pool power across a ring, so a member running near its PoE ceiling can draw spare capacity from a neighbor instead of forcing every unit in the stack to carry its own second supply.
C9300-48H-A includes a USB 3.0 SSD bay that accepts a 120 GB or 240 GB SSD module, letting operations teams capture and store packet traces directly on the switch instead of provisioning a separate capture appliance for closet-level troubleshooting.
Application Scenarios
Deployed as the access layer for full-floor camera, digital signage, and IoT lighting rollouts where the port count justifies a 48-port chassis and the 822W default budget covers a large share of endpoints without a second supply per unit.
Used as an access-layer switch in campus designs that rely on VRF or VXLAN segmentation and Cisco TrustSec policy enforcement at the edge, where the Network Advantage license already on this hardware avoids a separate license order.
Placed in a StackWise-480 stack alongside other C9300 Network Advantage members where StackPower pools power headroom across the ring, supporting floors that plan to add high-draw endpoints over time without pre-provisioning a second supply on every unit.

- Ordering C9300-48H-A instead of the base C9300-48H-E adds Network Advantage segmentation, unrestricted routed scale, and MACsec-256 on identical hardware; the ordering guide documents no in-place upgrade PID from Essentials to Advantage on standard C9300 modular-uplink hardware, so a design that starts on C9300-48H-E and later needs Advantage features has to re-order as C9300-48H-A rather than field-upgrade the license.
- Dropping to C9300-24H-A halves port count to 24 and caps the maximum PoE budget with a secondary supply at 2160W against 2880W on C9300-48H-A, which only costs anything when a floor’s high-draw endpoint count is already pushing past what one 24-port unit can carry; a closet that fits inside 24 UPOE+ ports gains nothing from the larger chassis.
- C9300-48P-A keeps the same 48-port count and identical 256 Gbps switching capacity but trades UPOE+ for PoE+, capping the default budget at 437W and the secondary-supply ceiling at 1440W versus 822W and 2880W on C9300-48H-A; that gap only matters when endpoints need more than a standard PoE+ 30W allocation per port.
- For deciding which SKU to order in this group, settle the per-port power class first (UPOE+ high-draw versus standard PoE+), then size port count against how many high-draw endpoints the floor actually needs; Network license tier and StackWise-480 stacking do not separate these three Advantage-tier models since all three already carry Network Advantage on the same stacking generation.
Selection Guide
1. 48-Port Chassis Consolidates Two 24-Port Stacks
C9300-48H-A carries an 822W PoE budget across 48 ports on one chassis; a floor that would otherwise need two 24-port C9300-24H-A units to cover the same endpoint count can consolidate onto a single 48-port unit instead, cutting the stack member count for the same PoE+ port total.
2. 2880W Ceiling Needs A Second Supply In The Order
Cisco’s documented ceiling only reaches 2880W once any second supply is installed, and upgrading the primary supply to PWR-C1-1900WAC-P alone does not raise the budget past the same design limit; a plan to grow past 822W of connected PoE load needs a second supply in the order, not just a bigger single supply.
3. No Field Path Off Network Essentials On This Chassis
Because no in-place upgrade PID moves standard C9300 modular-uplink hardware from Network Essentials to Network Advantage, C9300-48H-A only earns its higher tier over the lower-tier C9300-48H-E when Advantage-tier segmentation or automation is a known requirement, since the tier cannot be changed on the same chassis later.
4. UPOE+ Budget Gap Against The C9300-48P-A Sibling
C9300-48P-A shares the same 48-port count and 256 Gbps switching capacity as C9300-48H-A but caps its default budget at 437W and its secondary-supply ceiling at 1440W; a floor with any endpoints that need more than a standard PoE+ 30W allocation should size C9300-48H-A rather than assume the lower-cost PoE+ sibling has room to spare.
5. Empty Uplink Bay Leaves The Speed Choice Open
The modular uplink bay ships empty on C9300-48H-A, so the decision between a 10G SFP+ module (C9300-NM-8X), a 40G QSFP+ module (C9300-NM-2Q), or a 25G SFP28 module (C9300-NM-2Y) can wait until the distribution-layer uplink speed is confirmed, rather than being fixed at switch order.
PoE Power Planning
|
Planning Item |
Value or Check |
|---|---|
|
Default PoE budget |
822W with the single default PWR-C1-1100WAC-P supply, no secondary supply installed. |
|
Maximum PoE budget |
Up to 2722W with a 1900W secondary supply added to the default 1100W primary supply, rising to a 2880W design ceiling once the primary supply is also upgraded to PWR-C1-1900WAC-P; upgrading only the primary supply without a second supply does not raise the budget past 822W. |
|
UPOE+ port coverage |
Cisco documents Cisco UPOE+ (90W per port, IEEE 802.3bt Type 4) as available on 21 of the 48 ports when the switch is configured per datasheet Table 12. |
|
Secondary supply requirement for full UPOE+ |
Datasheet Table 12 specifies 1 PWR-C1-1100WAC/1100WAC-P plus 1 PWR-C1-715WAC/715WAC-P/715WDC, or 2 PWR-C1-1100WAC/1100WAC-P, or 2 PWR-C1-1900WAC-P/1900WHV-T, as qualifying pairs for UPOE+ on 21 ports. |
|
StackPower option |
StackPower can share power across up to 4 stacked members (8 with XPS-2200), reducing the need to size every unit’s PoE budget independently. |
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Second power supply need |
Confirm whether the connected PoE load will exceed 822W, and if so include a second supported power supply in the same order. |
The switch does not reach its 2880W ceiling on a single supply regardless of supply wattage. |
|
Network license and subscription match |
Confirm the Cisco Catalyst or Cisco DNA subscription ordered alongside C9300-48H-A is the Advantage tier, matching the built-in Network Advantage license. |
A mismatched subscription tier can stall activation or leave Advantage features unlicensed. |
|
Smart Account binding |
Confirm the target Smart Account and Virtual Account before ordering. |
Catalyst 9300 is a smart-licensed SKU; entitlements tied to the wrong account can delay activation. |
|
Uplink module selection |
Confirm which network module (C9300-NM-8X, C9300-NM-2Q, C9300-NM-2Y, C9300-NM-4M, or C9300-NM-4G) matches the distribution-layer uplink speed before the module ships as a separate line item. |
The uplink bay ships empty; the wrong module choice mismatches the intended uplink speed. |
|
Blank module for single-supply configuration |
Confirm a blank power supply module is ordered for the second bay when only one supply is installed. |
Cisco documents this as a caution for maintaining airflow and fan noise levels. |
