C9300-48UB-A Description
C9300-48UB-A is a Cisco Catalyst 9300 higher-scale stackable access switch in the Network Advantage tier, built for campus access layers that need dense powered copper connectivity with modular uplink flexibility. Cisco identifies it as a 48-port 10/100/1000 Cisco UPOE model, ships it with the PWR-C1-1100WAC-P default power supply for an 822W PoE budget, supports StackWise-480 and StackPower, uses the higher-scale Catalyst 9300 hardware profile, and introduces support from Cisco IOS XE Gibraltar 16.12.1.

Product Performance
Key Features
The `C9300-48UB` base model separates this SKU from the standard C9300-48U line by keeping 48 1G Cisco UPOE ports while adding the higher-scale Catalyst 9300 resource profile.
The `-A` suffix maps C9300-48UB-A to Network Advantage, while C9300-48UB-E is the matching higher-scale 48-port UPOE model with Network Essentials.
Cisco lists the higher-scale Gigabit Ethernet models with a 32-MB packet buffer, which is a buyer-visible distinction from standard modular-uplink C9300 Gigabit Ethernet models.
The higher-scale column lists 64,000 MAC addresses, 112,000 IPv4 routes, 56,000 IPv6 routing entries, 18,000 QoS entries, and 18,000 ACL scale entries.
Cisco states that C9300-24UB, C9300-24UXB, and C9300-48UB higher-scale SKUs need to be stacked with other higher-scale models.
C9300-48UB-A uses a modular uplink slot, and Cisco notes that the default switch configuration does not include the network module.
Application Scenarios
C9300-48UB-A fits a wiring closet that needs 48 1G Cisco UPOE copper ports and the higher-scale Catalyst 9300 buffer and table profile in one access switch.
Use this SKU when the bill of materials requires the higher-scale C9300-48UB hardware with Network Advantage instead of the Essentials-level C9300-48UB-E.
The model belongs in a Catalyst 9300 stack where every higher-scale member and the StackWise-480 cabling plan are checked before adding another 48-port UPOE switch.

- In a C9300-48UB-A vs C9300-48UB-E comparison, the hardware facts match on 48-port 1G UPOE, higher-scale profile, 32-MB buffer, and 822W PoE budget; the difference is Network Advantage versus Network Essentials.
- The C9300-48UB-A difference from C9300-48U-A is the scale profile: C9300-48UB-A stays in the higher-scale group with the larger buffer, MAC table, IPv4 route scale, and higher-scale stack boundary.
- For C9300-48UB-A vs C9300-24UB-A, the comparison is access density and performance, because both are higher-scale 1G UPOE Network Advantage models but the current SKU doubles the port count.
- C9300-48UB-A vs C9300-24UXB-A is the which model to choose check between 48-port 1G UPOE access and 24-port 10G/mGig UPOE access with a different buffer and capacity profile.
Selection Guide
1. Choose it for 48-port higher-scale UPOE
Select C9300-48UB-A when the access layer requires 48 Cisco UPOE copper ports plus the higher-scale Catalyst 9300 buffer, MAC, route, QoS, and ACL profile.
2. Use C9300-48UB-E only for Essentials
Keep the `-E` model for the same C9300-48UB hardware when the confirmed network license tier is Network Essentials rather than Network Advantage.
3. Avoid standard C9300-48U substitution when scale matters
Use C9300-48U-A only if the standard Catalyst 9300 modular-uplink scale profile is acceptable and the higher-scale C9300-48UB stack boundary is not required.
4. Separate 1G UPOE from mGig UPOE
Move to C9300-24UXB-A only when the design needs 10G/mGig UPOE downlinks instead of the 48-port 1G UPOE profile documented for C9300-48UB-A.
PoE Power Planning
|
Planning Item |
Cisco Confirmed Value |
Order Impact |
|---|---|---|
|
Default PoE budget |
C9300-48UB is listed with 822W available PoE and PWR-C1-1100WAC-P as the default supply |
Size the endpoint power plan against the base budget before adding secondary power |
|
UPOE access profile |
C9300-48UB is a 48-port 10/100/1000 Mbps Cisco UPOE model |
Prevents replacement with data-only, PoE+, UPOE+, or multigigabit order lines unless the access requirement changes |
|
StackPower support |
C9300-48UB-A supports StackPower |
Include StackPower cables only when the site design uses shared power across compatible Catalyst 9300 stack members |
|
Higher-scale stack group |
C9300-48UB higher-scale SKUs need other higher-scale stack members |
Confirm the stack member plan before using the SKU as a replacement for standard C9300-48U hardware |

What to Confirm |
Why It Matters |
|---|---|---|
|
Hardware line |
C9300-48UB-A |

|
Stack membership |
C9300-48UB higher-scale stack group |
Keep the planned stack within Cisco higher-scale C9300 members instead of mixing in standard C9300-48U hardware |
|
Uplink bay |
C9300 network module selected separately |
Add the required C9300-NM module because the default switch configuration does not include the network module |
|
Power design |
822W PoE budget with PWR-C1-1100WAC-P and StackPower support |
Compare endpoint power draw, secondary supply need, and StackPower cable use against the confirmed switch profile |
