C9300-48H-E Description
The C9300-48H-E is a Cisco Catalyst 9300 Series stackable access switch for floor wiring closets that power high-draw endpoints such as Wi-Fi access points and cameras over Cisco UPOE+. The switch has 48 10/100/1000 UPOE+ ports with an 822W default PoE budget, a modular uplink slot and 256 Gbps of switching capacity, with Network Essentials built in. The -E suffix covers Layer 2 and OSPF routing up to 1,000 routes but not VXLAN, Cisco TrustSec or MACsec-256.

Product Performance
Key Features
Cisco UPOE+ delivers 90W per port under IEEE 802.3bt Type 4. It reaches 21 of the 48 ports, and only with a qualifying pair of power supplies such as two 1100W units.
The default 1100W supply gives an 822W budget. A second 1900W supply lifts it to 2722W, and two 1900W supplies reach the 2880W design ceiling.
The slot takes hot-swappable network modules: C9300-NM-8X (eight 10G/1G SFP+), C9300-NM-2Q (two 40G QSFP+), C9300-NM-2Y (two 25G SFP28), C9300-NM-4M (four Multigigabit) or C9300-NM-4G (four 1G SFP). Uplink speed changes by swapping the module, not the switch.
Up to eight switches stack at 480 Gbps over StackWise cables, and only with other C9300 modular-uplink models on the same license tier. StackPower pools power across up to four members, or eight with XPS-2200.
Essentials covers Layer 2, routed access with OSPF up to 1,000 routes, PBR, PVLAN, VRRP, 802.1X and MACsec-128. BGP, VXLAN, MPLS and MACsec-256 sit outside the tier.
A rear bay takes a 120 GB or 240 GB USB 3.0 SSD module for local storage and packet capture, so closet troubleshooting does not need a separate capture appliance.
Application Scenarios
A building floor with PTZ cameras, digital signage and PoE lighting controllers can run from one closet, because the UPOE+ ports and 822W default budget power the high-draw devices directly.
On wireless-heavy floors, the switch powers access points that need more than PoE+ from its UPOE+ ports and carries their traffic to distribution over a 10G, 25G or 40G uplink module.
A floor that terminates its VLANs locally can route with OSPF up to 1,000 routes and authenticate endpoints with 802.1X, all within the Network Essentials tier of this switch.

C9300-48H-E and C9300-48H-A share 48 UPOE+ ports, the default 1100W supply and the 2880W PoE ceiling; C9300-48H-E runs Network Essentials, which covers Layer 2 and OSPF up to 1,000 routes. Networks that need VXLAN, Cisco TrustSec or MACsec-256 should order C9300-48H-A, or upgrade an installed C9300-48H-E later with a C9300-LIC= term (C9300-48-E-A-3, -5 or -7), which cannot be placed on the switch order. Sites that need 60W UPOE rather than 90W UPOE+ can use C9300-48U-E, whose expanded budget stops at 1800W. Where 30W PoE+ per port is enough, C9300-48P-E keeps the 48 ports with a 437W default budget and a 1440W ceiling, against 822W and 2880W here.
PoE Power Planning

UPOE+ class |
Cisco identifies the C9300-xxH family as UPOE+ and lists 90W Type 4 planning requirements for UPOE+ models |
Confirm endpoint power class instead of treating this SKU like a PoE+ or UPOE model |
|
Default PoE budget |
C9300-48H-E is listed with 822W available PoE and PWR-C1-1100WAC-P as the default supply |
Match powered endpoint count and endpoint draw to the base switch power budget |

Secondary supply choices |
The C9300-48H-E power table lists increased PoE budgets when secondary or upgraded power supplies are configured |
Decide whether the second supply is for redundancy, higher available PoE, or both |

Catalyst 9300 modular-uplink switches support StackPower |
Add StackPower cabling only when the site design uses shared power across stack members |
Ordering Checklist
- Subscription tier: Order a 48-port Essentials term: C9300-DNA-E-48 (Cisco DNA) or C9300-DNX-E-48-3Y/5Y/7Y (Cisco Catalyst). The configurator defaults to Advantage, which does not match a Network Essentials switch on a new order.
- Uplink module: Keep the default C9300-NM-8X, change it to another C9300-NM module, or select C9300-NM-NONE. The uplink slot must hold a module or be ordered empty, and the module is part of the switch order.
- Second power supply: A second PWR-C1-1100WAC-P is selected by default and C9300-SPS-NONE removes it. The second supply stays on the order unless removed, and a single-supply closet runs on the primary supply’s PoE budget.
- Stacking cables: The default 50 cm StackWise cable (C9300-STACK-NONE removes it) and default 30 cm StackPower cable (C9300-SPWR-NONE removes it) are both added by default. A standalone switch uses neither.
- Power cords: Select the cord type for the destination country; two cords ship with the order. The configurator defaults to North America cords.
