Cisco Catalyst 9500 Switches from M&F Collaboration are fixed-configuration campus core and aggregation platforms—10G SFP+ models (C9500-16X, 24X, 40X), 40G QSFP+ (12Q/24Q), and high-performance 25G/100G units (24Y4C, 48Y4C, 32C, 32QC). They're stocked for teams refreshing collapsed cores, adding StackWise Virtual pairs, or matching a specific Network Advantage (-A) or Essentials (-E) PID.

  • High-performance (UADP 3.0): 24/48×25G SFP28 with 100G uplinks, or dense 40/100G QSFP28 cores.
  • 10G aggregation: 16X baseboards, 24X (16X+NM-8X), and 40-port 40X with optional NM-2Q uplinks.
  • 40G QSFP+: 12Q and 24Q for legacy optic plants and spare.

Not sure whether you need 10G, 25G, or 100G—or -A versus -E? Request a quote and we'll match the PID to your fabric.

How to choose a Cisco Catalyst 9500 switch

The Catalyst 9500 is Cisco’s fixed core/aggregation family on IOS XE—not a modular 9400 chassis and not a stackable access 9300/9200. Start with port speed and density, then lock the license suffix and high-availability plan.

1. Match port speed to the fabric role

For 25G aggregation with 100G uplinks, start with C9500-24Y4C-A / C9500-24Y4C-E or denser C9500-48Y4C-A / C9500-48Y4C-E. Pure 100G cores use C9500-32C-A or flexible C9500-32QC-A (32×40G or 16×100G per Cisco). Stay on 10G fiber with C9500-16X-A / C9500-16X-E, the NM-8X bundle C9500-24X-E, or forty-port C9500-40X-A. Legacy 40G QSFP+ plants still map to C9500-12Q-A and C9500-24Q-A. Prefer Cisco datasheet speeds over marketplace titles that say “GE.”

2. Choose Network Advantage (-A) vs Essentials (-E)

The PID suffix is the perpetual network stack: -A unlocks advanced routing/segmentation and StackWise Virtual; -E covers foundational Layer 2/3 without SVL. Cisco DNA or Catalyst software subscriptions are separate term licenses—confirm Smart Account entitlements on refurbished units such as C9500-24Y4C-A-RF or C9500-16X-E-RF.

3. Understand 24X and 16X-2Q bundles

C9500-24X-E and C9500-24X-A-RF are C9500-16X chassis with the C9500-NM-8X eight-port 10G module (16+8=24). C9500-16X-2Q-A adds C9500-NM-2Q (two 40G QSFP+ uplinks). They are not separate ASIC families from the 16X baseboard.

4. Finish the BOM and related series

Add optics from Transceivers, fiber/DAC from Network Cables, and redundant supplies from Cisco Power Supplies.

For modular cores compare Catalyst 9400; for access stacking use 9300 or 9200. Cisco has announced end-of-sale for 12Q/24Q/40X—use them for like-for-like refresh; greenfield usually moves to Y4C or 32C/32QC.

Cross-check series selection in the Cisco Switch Buying Guide or compare cloud-managed options in Meraki MS vs Catalyst 9000.

Cisco Catalyst 9500 Switch FAQs

Is the Catalyst 9500 modular like the 9400?

No. The 9500 is fixed 1RU hardware. Only 16X/40X-class models take optional NM-8X or NM-2Q uplink modules. The 9400 is the modular supervisor/line-card chassis.

What do -A and -E mean on C9500 PIDs?

-A is Network Advantage (advanced routing and StackWise Virtual). -E is Network Essentials. DNA/Catalyst subscriptions are separate term licenses.

What is C9500-24X?

A C9500-16X with the C9500-NM-8X eight-port 10G module installed (24×10G SFP+ total). Same UADP 2.0 baseboard family as the 16X.

Do I need Advantage for StackWise Virtual?

Yes. Cisco recognizes SVL configuration only on Network Advantage. Essentials switches cannot form an SVL pair.

When should I choose 24Y4C instead of 16X?

Choose 24Y4C/48Y4C when you need multi-rate 1/10/25G SFP28 ports and fixed 40/100G uplinks on UADP 3.0. Stay on 16X/24X/40X when the design is still pure 10G SFP+.

Are C9500-40X and 12Q/24Q still available?

Yes in our catalog for refresh and spare. Cisco has announced end-of-sale for those models; new designs typically move to 24Y4C/48Y4C or 32C/32QC.

Where do I add optics and power supplies?

Browse Transceivers and Cisco Power Supplies, then send the full PID list via the RFQ form.
