Cisco Catalyst SWITCH WS-C3650-48PD-L

Overview on the Cisco Catalyst WS-C3650-48PD-L

The Cisco Catalyst WS-C3650-48PD-L Switch is a premier, standalone, and stackable Layer 3 access switch. It delivers full infrastructure convergence by bridging your wired and wireless traffic on a single platform. Therefore, it is designed perfectly for medium enterprise branches, large campus wiring closets, and high-density commercial operations. This heavy-duty 1U rackmount unit comes engineered with 48 autosensing 10/100/1000 RJ-45 PoE+ ports. Driven by Cisco’s advanced Unified Access Data Plane (UADP) ASIC architecture, this platform enforces uniform security policies, fine-grained application visibility, and optimization profiles across physical cables and wireless access points alike.

This high-performance switch prioritizes reliable network expansion alongside dependable power delivery. It features a fixed, integrated uplink configuration providing two 10G SFP+ and two 1G SFP transceiver channels. By incorporating native 10-Gigabit distribution options, this system lets IT professionals establish ultra-fast uplink lines. Consequently, you can link directly to your core distribution infrastructure or localized server rooms without creating traffic bottlenecks. At its interior, a powerful multicore processor pairs with 4 GB of RAM and 2 GB of Flash memory. These resources allow the switch to run complex operations smoothly while delivering a switching capacity of 176 Gbps and a max throughput of 104.16 Mpps.
