Cisco Catalyst 9500 C9500-48Y4C-A Switch Overview
The Cisco Catalyst 9500 C9500-48Y4C-A is a high-performance core and distribution switch. It provides 48 ports of 1G/10G/25G SFP+ plus 4 ports of 40G/100G QSFP28, making it suited to campus core, distribution and data-center aggregation. As an -A SKU it runs the Network Advantage feature set, delivering the advanced routing and security features that core roles require. Every unit sold by LinkNewNet is tested and carries a 3-month warranty.
This unit follows the original factory specification for the Cisco family, covering its intended role without compatibility surprises. Standard mounting, cabling and management practices apply, and it interoperates with surrounding hardware using the same procedures as other Cisco equipment already deployed in the network.
Typical deployments include access-layer deployments for user, phone and AP connectivity, distribution and core aggregation in campus networks, and top-of-rack and end-of-row switching in data centers. Organizations commonly source it for refresh programs, capacity expansion and spares management, keeping a tested unit on hand so outages stay short and replacements are predictable. The factory detail for this unit reads: “Cisco Catalyst 9500 48-port x 1/10/25G + 4-port 40/100G, Advantage”. This makes it a practical choice when original-spec hardware is required at a predictable cost.
Every unit at LinkNewNet is inspected and tested before dispatch, and stock is graded, cleaned and verified for correct operation, including port status, console access and firmware state. Our warranty coverage and responsive technical support protect the purchase after it arrives, and our team can confirm revision levels and software compatibility before you order. For volume requirements we also offer configuration checks and staged delivery options.

C9500-48Y4C-A vs. C9500-24Y4C-A: Which to Choose
The Catalyst 9500 Y4C series is available as the C9500-48Y4C-A (this page) and the lower-density C9500-24Y4C-A. The -48Y4C offers 48 x 1/10/25G ports with 4 x 40/100G uplinks, while the -24Y4C gives you 24 x 1/10/25G ports with 4 x 40/100G uplinks. Both run the same Catalyst 9500 software and Network Advantage tier - pick the 48-port model if you need higher 10/25G density at the core or distribution layer.
