Cisco Catalyst 9300 48-Port PoE+ Switch

The Cisco Catalyst 9300-48P is a 1U stackable enterprise-access switch with 48× 10/100/1000 (GbE) RJ-45 ports, every port PoE+ (IEEE 802.3at) on a 437 W system power budget.

It runs Cisco IOS-XE (ships 17.x; 16.x-capable) and carries the Network Advantage feature set denoted by the -A suffix — full L2/L3 routing, SD-Access fabric edge, MACsec-256, and programmability via NETCONF/RESTCONF, YANG models and on-box Python. A field-replaceable uplink module slot accepts 4× 1G, 4×/8× 10G, 2× 25G or 2× 40G optics, so the same chassis backhauls at 1G today and 40G later.

StackWise-480 delivers 480 Gbps of stacking bandwidth across up to 8 members that manage as a single logical switch; StackPower rings up to 4 chassis for shared, redundant PoE. Switching capacity is 176 Gbps at a 130.95 Mpps forwarding rate, with 16 GB flash and 8 GB DRAM for application hosting and telemetry.

Shipped seller-refurbished: chassis inspected, all 48 ports link-tested, PoE load-verified, the uplink module exercised, IOS-XE version recorded, and the configuration and credentials zeroed to factory default — covered by a 365-day owned warranty with seller-paid RMA freight and zero restocking fee.
