C9500-48Y4C-E Description
C9500-48Y4C-E is a Cisco Catalyst 9500 Series fixed core and aggregation switch with Network Essentials licensing, built for fiber-dense campus or aggregation layers that need high-speed downlink and uplink capacity in a 1 RU platform. It provides 48 1G/10G/25G SFP28 ports and four fixed 40G/100G QSFP28 uplinks, supports up to 3.2 Tbps switching capacity and 1 Bpps forwarding, uses two power-supply slots with C9K-PWR-650WAC-R as the default AC supply option, and has Cisco IOS XE Fuji 16.8.1a as the minimum software release for this model.

Product Performance
Key Features
The -E suffix identifies the Network Essentials version of the C9500-48Y4C hardware, so the PID should align with an Essentials software subscription path.
The C9500-48Y4C model doubles the SFP28 port count of C9500-24Y4C while keeping the same 1G, 10G, and 25G capable access-facing port speeds.
Cisco documents four 40G or 100G uplink ports on this hardware, making the QSFP28 optics plan part of the switch order rather than a separate network-module decision.
The data sheet lists C9500-NM-8X and C9500-NM-2Q as unsupported on C9500-48Y4C, so uplink planning must use the fixed QSFP28 ports.
The supported power options are C9K-PWR-650WAC-R, C9K-PWR-650WACL-R, and C9K-PWR-930WDC-R, which keeps this BOM outside the 1600W supply family used by C9500-32C.
C9500-48Y4C uses the C9K-T1-FANTRAY path with up to four fans, matching the C9500-24Y4C and C9500-32QC cooling spare family.
Application Scenarios
C9500-48Y4C-E fits campus core or distribution blocks that need 48 fiber-facing SFP28 ports and four high-speed QSFP28 uplinks under an Essentials network tier.
Use this SKU when the design standard is Network Essentials and the uplink plan can be built from the four fixed 40G or 100G ports without optional C9500 network modules.
This model suits refresh projects that outgrow the 24-port 25G footprint of C9500-24Y4C-E but do not need the 32-port 100G density of C9500-32C hardware.

- In a C9500-48Y4C-E vs C9500-48Y4C-A comparison, the hardware profile, port count, fixed uplinks, power supplies, fan tray, and software floor stay the same; the confirmed difference is Network Essentials versus Network Advantage.
- The C9500-48Y4C-E vs C9500-24Y4C-E difference is SFP28 density and switching capacity, because the C9500-48Y4C model lists 48 SFP28 ports and up to 3.2 Tbps while C9500-24Y4C lists 24 SFP28 ports and up to 2.0 Tbps.
- For buyers deciding which model to choose, C9500-48Y4C-E is the Essentials PID for the 48-port 25G hardware profile rather than the Advantage suffix or the smaller 24-port platform.
Selection Guide
1. Match it to 48-port Essentials requirements
Choose C9500-48Y4C-E when the approved design needs 48 SFP28 ports, four fixed 40G/100G uplinks, and the Network Essentials tier.
2. Use C9500-48Y4C-A for the same hardware with Advantage
Select C9500-48Y4C-A when the physical port layout remains C9500-48Y4C but the network license requirement changes to Network Advantage.
3. Drop to C9500-24Y4C-E only for lower port density
Review C9500-24Y4C-E when 24 SFP28 ports are enough and the design does not need the 3.2 Tbps C9500-48Y4C hardware ceiling.
4. Close the optics and software checks before ordering
Validate exact SFP28 and QSFP28 transceivers, Cisco IOS XE release support, Smart Account readiness, subscription term, power supply type, and rack depth before releasing the purchase line.
