C9300-48P-A

The Cisco Catalyst C9300-48P-A is a 48-port PoE+ Gigabit Ethernet access switch for enterprise campus closets, branch networks, and refresh projects that need Cisco Catalyst 9000 security with the richer Network Advantage feature set. It provides 48 10/100/1000 copper downlinks for user devices, IP phones, wireless access points, cameras, and other powered endpoints, while the modular uplink slot lets teams select the fiber or high-speed uplink module that matches their distribution layer. The -A license identifies Network Advantage, making this SKU suitable for routed access, advanced segmentation, policy, automation, telemetry, and resilient IOS XE operations managed through CLI, Cisco Catalyst Center, or existing monitoring workflows. It is especially useful where organizations want consistent switch behavior across access closets while keeping uplink choices flexible for different building designs.

For PoE planning, C9300-48P-A ships with a 715W AC power supply and offers a 437W PoE budget by default. That capacity works well for common edge mixes such as IP phones, standard wireless access points, badge readers, surveillance cameras, and other 802.3at devices. Cisco dual redundant power supply support allows a second supply to be added for resiliency or a larger power pool, and StackPower can share power across supported Catalyst 9300 stack members. The chassis also includes field-replaceable fans with N+1 redundancy, helping the switch serve access closets where uptime, serviceability, and predictable maintenance windows matter. Perpetual PoE and Fast PoE are useful for environments where phones, cameras, and wireless devices should recover quickly after planned work or a power interruption. These capabilities reduce the need for local adapters and simplify endpoint moves when offices are reconfigured or new security devices are added.

Performance is another reason to choose the 9300 family for standardized enterprise access. The C9300-48P platform delivers 256 Gbps switching capacity, 736 Gbps switching capacity with stacking, and 190.47 Mpps forwarding, while StackWise-480 lets multiple switches operate as one logical system. It also provides 32,000 MAC addresses, 8 GB DRAM, and 16 GB flash, giving the platform headroom for policy, telemetry, and operational growth. Because the base switch does not include an uplink module, buyers can match the deployment to 1G SFP, 10G SFP+, 25G SFP28, 40G QSFP, or multigigabit uplink needs without replacing the access switch later. That flexibility is valuable in multi-building environments where fiber standards and distribution capacity may differ by site during phased upgrades over several fiscal cycles. For ORM Systems customers, C9300-48P-A is a practical choice when procurement needs Cisco Catalyst security, PoE+ endpoint power, Network Advantage capabilities, modular uplink flexibility, stackable growth, and a documented license for enterprise campus or branch access refresh work.
