Cisco Catalyst 3750V2-48PS vs Catalyst 9300-48P
The WS-C3750V2-48PS-S is an end-of-life Fast Ethernet StackWise PoE switch; the Catalyst 9300 C9300-48P-A is its modern Gigabit PoE+ replacement with StackWise-480, UADP silicon, and IOS-XE. For any stacked access refresh, migrate to the C9300-48P-A for Gigabit ports, far more PoE and stack bandwidth, and current security.

| Forwarding rate | 6.5 Mpps | Multi-hundred Mpps (UADP) |
| Software | Classic Cisco IOS (IP Base) | Cisco IOS-XE (Network Advantage) |
| Redundant power | Optional RPS (external) | Dual internal field-replaceable PSUs |
| Lifecycle status | End of sale and end of support | Current, actively supported |
Choose Cisco Catalyst 3750V2-48PS if
There is no new-purchase case for the 3750V2-48PS; retain it only short term in an existing stack where 10/100 endpoints and low PoE demand defer the swap and support risk is accepted.
Choose Cisco Catalyst 9300-48P if
Choose the C9300-48P-A for any stacked access-layer refresh that needs Gigabit PoE+, high stack bandwidth, 10/25/40G uplinks, redundant power, and supportable IOS-XE with Catalyst Center.
Verdict
Migrate from the Catalyst 3750V2-48PS to the C9300-48P-A. The 3750V2 is end of support, limited to 100 Mbps ports, 802.3af, and a 32 Gbps stack, while the C9300 delivers Gigabit PoE+, a 480 Gbps StackWise ring, modular high-speed uplinks, and current security. Keep 3750V2 stacks only as a brief bridge.
Frequently asked questions
Is the Cisco Catalyst 3750V2-48PS end of life?
Yes. The WS-C3750V2-48PS-S has reached end of sale and end of support, so it no longer receives software or security maintenance and should be replaced.
What replaces the Catalyst 3750V2 stack?
The Catalyst 9300 Series, specifically the C9300-48P-A for 48-port PoE+, is the modern stackable replacement with Gigabit ports, StackWise-480, and IOS-XE.
How much faster is C9300 stacking than the 3750V2?
The C9300 uses StackWise-480 at 480 Gbps versus the 3750V2's 32 Gbps StackWise ring, a roughly 15x increase in stack bandwidth.
Does the C9300-48P-A support faster uplinks than the 3750V2?
Yes. The 3750V2 used fixed 1G SFP uplinks, while the C9300 offers modular network modules supporting 10G, 25G, and 40G uplinks.
