WS-C2950T-48-SI is a managed Layer 2 switch with 48 Fast Ethernet access ports and two fixed 10/100/1000BASE-T copper uplinks. The non-PoE configuration connects separately powered endpoints, while its full-width 1U chassis mounts in a standard equipment rack. Within the Catalyst 2950 family, Standard Image software provides basic data, voice, and video switching functions for small and midsize networks. The discontinued WS-C2950SX-48-SI changes the uplink medium to fixed 1000BASE-SX fiber rather than copper. This 48-port Fast Ethernet switch therefore matches legacy workgroup cabling where endpoint connections remain at 10/100 Mbps and the upstream connection uses twisted-pair Gigabit Ethernet.

13.6 Gbps switching capacity accommodates traffic across the fixed interfaces. The 16 MB DRAM supports switch operation, while 8 MB flash stores the software image and configuration files. WS-C2950T-48-SI supports IGMP snooping to constrain multicast forwarding to interested receivers rather than flooding every connection. Local console administration provides a configuration path before network-based management is established. 45W maximum power consumption provides the equipment load for power-distribution planning without an endpoint-power allowance. Autoranging AC input accepts 100–127V or 200–240V, and the rear RPS connector provides a separate external backup-power connection rather than a second internal supply bay. Operation from 0°C to 45°C requires an installation that maintains the permitted ambient temperature and leaves the fan exhaust unobstructed. Switch clustering provides grouped administration, not a dedicated hardware stacking backplane.

When a staging environment must reproduce an existing segmented network, the Standard Image configuration supports 64 port-based VLANs. The purchase decision should follow the intended configuration rather than connector count alone. Confirm the required VLAN inventory and prepare the corresponding configuration before specifying the staged units on the PO.
When an existing branch configuration depends on traffic prioritization, four egress queues support weighted round-robin and strict-priority scheduling. Retaining the same scheduling behavior is a separate purchasing trigger from adding endpoint connections. Identify the required queue mappings and scheduling settings, then include configuration validation in the rollout checklist before ordering.
Gigabit speed on every access connection
The 48 access interfaces stop at 100 Mbps. Gigabit operation is limited to the two copper uplinks, so endpoint Gigabit connectivity requires different hardware.
Power delivery to connected endpoints
The access ports do not provide PoE. Phones, access points, or other powered devices require their own power arrangements rather than power from these interfaces.
Removable fiber uplink interfaces
The two uplinks are fixed copper interfaces. The chassis has no removable uplink module bay or optical transceiver slots for changing the connection medium.

WS-C2950T-48-SI identifies a Cisco Catalyst 2950 switch with copper Gigabit uplinks, 48 Fast Ethernet access ports, and Standard Image software. WS-C is the Cisco Catalyst switch prefix, 2950 identifies the family, T distinguishes the copper-uplink configuration, 48 identifies access-port density, and SI identifies Standard Image.
WS-C2950T-48-SI supports Cisco Network Assistant, embedded CMS, the Cisco IOS CLI through console or Telnet, CiscoView, SNMP management, and Cisco Intelligence Engine 2100 configuration services. The rear console connection provides local access for initial configuration, while network management requires the appropriate connectivity and management settings.
WS-C2950T-48-SI belongs to the retired Catalyst 2950 family, and Cisco service has ended. The switch should be treated as legacy equipment rather than a current Cisco-supported purchase. Replacement planning must distinguish continued operation of existing hardware from eligibility for an active manufacturer support arrangement.
ORM Systems offers WS-C2950T-48-SI new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Cisco warranty coverage has ended. Every condition includes 30-day returns, terms apply; refurbished managed units are inspected, bench-tested, firmware verified, and factory-default wiped.
WS-C2950T-48-SI comes with Standard Image software for basic data, voice, and video switching services. Standard Image and Enhanced Image are distinct Catalyst 2950 feature sets associated with different models. A purchase specification should identify Standard Image explicitly rather than assuming the feature set of another family member.
WS-C2950T-48-SI has two fixed 10/100/1000BASE-T copper uplinks in addition to its 48 Fast Ethernet access ports. These uplinks use RJ-45 connections rather than optical transceivers. The fixed construction provides no uplink module bay for substituting fiber interfaces or increasing the uplink speed.
No, WS-C2950T-48-SI does not have two internal power-supply bays; backup power uses its external RPS connection. The internal AC supply accepts 100–127V or 200–240V, and maximum switch consumption is 45W. An external backup-power arrangement is separate from the internal supply configuration.
WS-C2950T-48-SI does not provide a dedicated hardware stacking backplane; Catalyst 2950 clustering provides grouped management instead. Connecting switches through Ethernet uplinks does not turn those connections into dedicated stack interfaces. Buyers expanding an existing installation should distinguish shared administration from the forwarding architecture of a hardware stack.
No, WS-C2950T-48-SI is a Layer 2 switch and does not perform inter-VLAN routing. VLANs separate traffic within the switched network, but communication between those VLANs requires an external routing device. Standard Image switching functions should not be confused with the routed-access capabilities of later switch families.
WS-C2950T-48-SI uses two fixed 10/100/1000BASE-T copper uplinks, whereas WS-C2950SX-48-SI uses two fixed 1000BASE-SX fiber uplinks. Both models are discontinued. The copper model matches existing twisted-pair uplink connections; the fiber model corresponds to installations using the fixed optical uplink medium rather than removable transceivers.
WS-C2950T-48-SI uses Standard Image software, whereas WS-C2950T-24 uses Enhanced Image software. Both models are discontinued. The software distinction matters when matching an existing configuration: Standard Image serves basic switching requirements, while Enhanced Image adds security and quality-of-service functions that should not be assumed on the SI model.
WS-C2950T-48-SI provides 48 Fast Ethernet access ports, compared with 24 on WS-C2950-24. Both models are discontinued and use Standard Image software. For an existing legacy installation, the former accommodates a larger endpoint inventory, while the latter corresponds to a smaller access-port requirement within the same switch family.
