Applications
The Catalyst 2948G is a wiring closet and access-layer switch from Cisco's late-1990s/early-2000s Catalyst fixed-configuration line. In enterprise campus networks of that era, switches like the 2948G were deployed at the access layer to aggregate workstations, IP phones, and printers and uplink them via GBIC to a distribution-layer switch such as a Catalyst 4500 or 6500. The shared Catalyst System Software codebase meant it participated fully in features like VLANs, Spanning Tree Protocol (STP), and SNMP-based management through CiscoWorks2000, making it straightforward to integrate into an existing Cisco infrastructure. Today the WS-C2948G is most commonly found in legacy network maintenance, lab environments, Cisco certification (CCNA/CCNP) study labs, and low-traffic secondary network segments where 10/100 access-layer switching remains adequate.
This Cisco WS-C2948G Catalyst 2948G 48-Port 10/100 Layer 2 Switch has been inspected and appears to be in good used condition. The unit shows normal wear consistent with prior rack deployment — the chassis and front panel are intact with no significant damage visible. All 48 RJ-45 ports and both GBIC uplink slots appear undamaged. The rear fans, power inlet, and RPS connector area are all present and show no obvious physical issues. It was pulled from a working network environment where it was previously in service and has not been bench-tested at our facility. Please view our photo set and contact us if you have any questions.
