Description

The Catalyst 9300 24-port Multigigabit UPOE switch is a stackable enterprise access switch for campus and branch networks, built for high-bandwidth Wi-Fi 6/6E access points and PoE endpoints such as IP phones, cameras and IoT devices. As a higher-scale, deep-buffer model, it suits multimedia and lossless content delivery where larger tables and bigger buffers matter.

All 24 downlink ports run at 10G, 5G, 2.5G, 1G or 100M with Cisco UPOE at up to 60W per port. Uplinks are modular, so the switch can move from 1G to 10G, 25G or 40G with C9300 network modules. It provides 640 Gbps switching capacity (1120 Gbps with stacking), a 476.19 Mpps forwarding rate and a 64 MB packet buffer. The default 1100W AC Platinum power supply delivers a 560W PoE budget, rising to a maximum of 1440W with a second supply. This SKU carries the perpetual Network Essentials licence tier.

It stacks over StackWise-480 with up to 8 members and supports StackPower, but only with other C9300 higher-scale models at the same licence level. It accepts C9300 network modules and the PWR-C1 series power supplies.

FAQs

Q: Which licence does this switch use?
A: It uses the perpetual Network Essentials licence tier. A Cisco Catalyst or DNA Essentials subscription term must be ordered with a new switch and must match the network licence tier. Advanced routing such as BGP, VRF and MACsec-256 needs Network Advantage.

Q: How much PoE power is available?
A: With the default 1100W AC power supply the PoE budget is 560W. Adding a second power supply raises it to 910W with a 350W unit, 1275W with a 715W unit and 1440W with an 1100W or 1900W unit.

Q: Which network modules and power supplies does it work with?
A: It accepts C9300 network modules: C9300-NM-4G, -4M, -8X, -2Q and -2Y. C9300X modules are not supported. Compatible power supplies are PWR-C1-1100WAC-P, PWR-C1-715WAC-P, PWR-C1-350WAC-P, PWR-C1-1900WAC-P and PWR-C1-1900WHV-T.

Q: Can it be stacked with other Catalyst 9300 switches?
A: Yes, but only with other C9300 higher-scale models (C9300-24UB, C9300-24UXB, C9300-48UB) at the same licence level. It cannot be mixed with standard C9300, C9300X, C9300L or C9300LM models.

Q: How does this model differ from the standard Catalyst 9300 24-port mGig switch?
A: This is the higher-scale deep-buffer variant with a 64 MB packet buffer and larger MAC, routing and NetFlow tables. It also has modular uplinks and ships with the 1100W AC power supply.
