Cisco C9500-24Y4C-E Catalyst 9500 Switch – 24x 25G SFP28, 4x 100G, Network Essentials

About the C9500-24Y4C-E

On the C9500-24Y4C-E, each of the 24 SFP28 downlink ports runs at 1G, 10G or 25G, and four fixed QSFP28 ports handle 40G or 100G uplinks. The switch is 1U, runs Cisco IOS XE with the Network Essentials software tier, and has no PoE. Switching capacity reaches 2.0 Tbps and forwarding reaches 1 Bpps.

Power is 1+1 redundant, with one power supply included. The AC options are the C9K-PWR-650WAC-R, with a 20 ms hold-up, and the C9K-PWR-650WACL-R, with a 12 ms hold-up. The C9K-PWR-930WDC-R is the DC option.

This model has no stacking ports. Cisco StackWise Virtual joins two switches as one over their data ports. The C9500-24Y4C-A is the Network Advantage version of this model.
