Cisco WS-C3560G-48S-S Catalyst 3560 Series 48-Port Gigabit Ethernet Layer 3 Switch with 4 SFP Uplinks: This is a Cisco Catalyst 3560 Series fixed-configuration enterprise-class managed Layer 3 switch. The 48 access ports operate at 10/100/1000 Mbps; the four SFP slots provide Gigabit Ethernet fiber uplinks. The trailing "-S" software suffix denotes the IP Base feature set (basic Layer 2/3 with limited routing protocols, not the full IP Services image). This is a non-stackable platform; the 3560 family does not support StackWise. This unit is refurbished, lab-tested by T.E.S IT-SOLUTIONS.
Engineering Context
The Catalyst 3560 runs Cisco IOS Software with the IP Base feature set, providing static routing, RIP, EIGRP-stub, OSPF (limited), inter-VLAN routing, and basic IP multicast (PIM-DM/SM). Switching capacity on the 48-port G models is up to 32 Gb/s with a 38.7 Mpps forwarding rate at 64-byte packets. The chassis carries 32 MB of internal flash and 128 MB of DRAM. Configuration is via console (RJ-45), Telnet, SSH, SNMPv1/v2c/v3, or HTTPS. The 3560 family supports Cisco prestandard PoE and IEEE 802.3af PoE on PoE-equipped variants of this chassis line; verify the chassis label for PoE configuration.
Deployment & Use Cases
Access-layer wiring closets in branch offices and small campus deployments. Edge-of-LAN switching for IP telephony (Cisco UC), IP video surveillance, and 802.11 wireless access point backhaul. Distribution to fiber uplinks where copper runs cannot reach. Replacement of legacy 2950/3550 switches in PCI-DSS environments where hardware ACLs and Layer 3 routing are required.

Compatibility & Hard Constraints
Compatible with standard Cisco SFP modules (GLC-T, GLC-SX-MM, GLC-LH-SM, GLC-ZX-SM, etc.). Will accept third-party SFPs only when the "service unsupported-transceiver" CLI command is enabled. Does NOT support StackWise stacking; the 3560 series is a standalone platform (the 3750 series provides shared-backplane stacking). The IP Base image does NOT include full IP Services features such as advanced multicast (MSDP), unrestricted policy-based routing, or VRF Lite; an IP Services upgrade is required for those. Reached end-of-software-maintenance per Cisco lifecycle bulletin; check current image availability before deployment in PCI/HIPAA-regulated environments. Verify exact PoE configuration via the chassis label and product photos before ordering.
