C9300-48S-E Description
The C9300-48S-E is a Cisco Catalyst 9300 Series stackable access switch for wiring closets that terminate fiber runs over 1G SFP. The switch has 48 1G SFP ports, a modular uplink slot and 256 Gbps of switching capacity, and its 715W AC supply carries no PoE budget because SFP ports do not source power. The -E suffix carries Network Essentials, which covers Layer 2 and OSPF routing up to 1,000 routes but not BGP, VXLAN or MPLS.

Product Performance
Key Features
All 48 downlinks are 1G SFP, so one chassis terminates a full floor of fiber drops. Single-mode and multimode links share the same cages, selected by the optic installed.
The default 715W AC supply feeds the switch alone, since SFP ports do not source PoE. Endpoints that need inline power connect through a separate powered switch.
Network Essentials covers Layer 2, OSPF up to 1,000 routes, VRRP, 802.1X and MACsec-128. BGP, VRF, VXLAN, TrustSec and MACsec-256 sit in Network Advantage.
The modular slot takes C9300-NM-4G, C9300-NM-8X, C9300-NM-2Q, C9300-NM-2Y or C9300-NM-4M modules. Moving from 10G to 25G or 40G uplinks means swapping the module rather than the switch.
Up to eight units join one stack at 480 Gbps, and every member must run the same license tier. StackPower is available for sharing power across the stack.
The 1G fiber models start at Cisco IOS XE 16.11.1a, while the copper Catalyst 9300 models start at 16.5.1a. A stack that mixes the two runs a release that supports both.
Application Scenarios
In a building wiring closet that terminates fiber drops, the switch lands up to 48 links on its 1G SFP ports and carries their traffic to the distribution layer through the modular uplink.
Where a cable run exceeds the 100 m limit of copper, as between buildings on a campus, the switch connects the far end over single-mode or multimode SFP optics without a media converter.
A small campus building can stack up to eight of these switches over StackWise-480, so the group operates as one logical switch with 480 Gbps of stack bandwidth.

Cisco IOS XE 16.5.1a |
C9300-48S-E and C9300-48T-E share 256 Gbps of switching capacity, a modular uplink slot and the Network Essentials tier, but C9300-48S-E has 48 SFP fiber ports on a 715W supply where C9300-48T-E has 48 copper ports on a 350W supply, and neither provides PoE. Closets whose endpoints are within copper reach and have no fiber plant can use C9300-48T-E, which also runs from Cisco IOS XE 16.5.1a instead of 16.11.1a. Closets that need only 24 fiber drops can use C9300-24S-E, which has 208 Gbps of switching capacity and the same 715W supply. When BGP, VRF, VXLAN or Cisco TrustSec is needed, order C9300-48S-A; an installed C9300-48S-E can be upgraded with a C9300-LIC= term (C9300-48-E-A-3, -5 or -7), which cannot be placed on the switch order.
Ordering Checklist
- Software subscription: Order an Essentials term for the 48-port fiber group, such as C9300-DNX-E-48S-5Y or C9300-DNA-E-48S-5Y (3, 5 or 7 years). The configurator defaults to Advantage, which does not match a Network Essentials switch.
- Uplink module: Keep the default C9300-NM-8X, change it to another Catalyst 9300 network module, or select C9300-NM-NONE. The configurator fills the modular uplink slot, so the default adds a module to the order.
- Second power supply: A second supply matching the primary is selected by default and C9300-SPS-NONE removes it. Leaving the default adds a second supply to the order; removing it leaves the switch on a single supply.
- Stack cables: A 50 cm StackWise cable and a 30 cm StackPower cable are selected by default; C9300-STACK-NONE and C9300-SPWR-NONE remove them. A stack across racks needs longer cables ordered separately, and a standalone switch needs neither default.
- Power cords: Select the cord type for the destination country. The configurator defaults to North America cords and ships two.
