Cisco Catalyst 9300 Series

Cisco logo

IT teams need a consistent access layer that can handle mixed endpoint demand without turning every closet into a one-off design, and Catalyst 9300 Series gives them that standard. It supports PoE access, fibre links, multigigabit copper and stackable control, so smaller floors, branches and denser office areas can keep users, phones, cameras and APs on the same managed platform.

In hybrid offices, remote cabinets and campus edge spaces, it helps maintain segmentation, telemetry and policy control while reducing the need for separate switches, injectors or local workarounds. That keeps day-to-day moves, adds, changes and troubleshooting more predictable, supports growth without redesign, and avoids access bottlenecks as device demand changes.

Cisco Catalyst 9300 Series Quick Specs & Key Features

  • Secure PoE access: 24- and 48-port PoE models connect desks, phones, cameras and access points on one Catalyst 9300 access layer, with policy control and segmentation that keep mixed services separated so smaller floors and branches are easier to run.
  • Stackable enterprise platform: StackWise support lets multiple switches operate as one logical unit, so moves, adds, changes and fault handling stay simpler across hybrid offices, clinical areas, regulated floors and guest-facing sites.
  • Modular uplink architecture: Modular uplink options let each switch adapt to fibre or copper backhaul, so teams can match the access block to distance, isolation and structured cabling needs without redesigning the closet.

  • Multigigabit copper access: Multigigabit port options support Wi-Fi 6/6E access points and other high-throughput endpoints over existing cabling, so organisations can lift access speed without a full recable and reduce deployment disruption.
  • High-power UPOE support: Higher-power UPOE variants deliver power and data from the same port to demanding AP, AV and smart-building devices, so teams avoid separate injectors and lower local hardware overhead.
  • Fibre access switching: SFP-based 24-port models provide fibre connectivity for remote cabinets and aggregation links, and their electrical isolation supports long runs and separated network segments so availability improves where copper is not suitable.

Cisco Catalyst 9300 Series Deployment Scenarios and Industries

Hotels and Hospitality

Hotels need access networks that can handle guest Wi-Fi, room systems, POS terminals, IPTV, phones, cameras and back-office traffic across many service areas. Catalyst 9300 switches help teams keep these devices powered, segmented and easier to support during busy periods.

Healthcare

Healthcare sites depend on reliable connectivity for workstations, carts, phones, cameras and wireless access, while clinical, admin and guest traffic must stay separated. Catalyst 9300 switches support secure PoE access and consistent policy control across floors and branches.

Professional Services

Professional services offices need access layers that can cope with desk moves, meeting-room changes and guest connectivity without creating a custom design for every floor. Catalyst 9300 switches provide stacked PoE access with policy and telemetry that simplify day-to-day changes.

Finance

Finance teams need dependable access for users, phones, cameras and wireless, with clear segmentation for regulated traffic and customer-facing systems. Catalyst 9300 switches give IT teams a controlled access platform for smaller closets and larger office floors.

Media & Entertainment

Media teams move large files, support edit suites and review spaces, and often need faster copper access for wireless-heavy collaboration and demanding devices. Catalyst 9300 switches help keep creative traffic, APs and powered endpoints on one managed access layer.
