WS-C2950G-12-EI is a managed Layer 2 switch with 12 non-PoE 10/100 Ethernet access ports and two fixed Gigabit GBIC uplink slots. Enhanced Image software adds rate limiting and security filtering to the Cisco Catalyst 2950 feature set. The full-width rack chassis serves legacy small-business and branch networks retaining Fast Ethernet endpoints. WS-C2950G-24-EI provides 24 access ports instead of 12; both models are discontinued. Catalyst 2950G-12 supports copper or fiber uplink connections through compatible GBIC transceivers.

13.6 Gbps switching capacity provides the internal switching fabric, while 4.8 Mpps forwarding handles 64-byte packets. The model's maximum forwarding bandwidth is 6.4 Gbps. WS-C2950G-12-EI combines 16 MB DRAM and 8 MB flash with an 8000-entry MAC address table. STP, RSTP and LACP support loop control and link aggregation. Layer 3 traffic classification does not make the hardware an IP-routing switch.
WS-C2950G-12-EI is offered by ORM Systems in new sealed and certified refurbished condition. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status and fan status; firmware is verified and configuration is wiped to factory default. New units carry up to 3-year extended warranty and certified refurbished units up to 1 year, with 30-day returns on every condition; terms apply. Specify condition, uplink components and quantity on the purchase order; PO accepted, Net-30 for government, and RMA with advance replacement support enterprise and volume orders.

When a lab must reproduce an existing traffic-priority configuration, four egress queues per port provide separate queues for the test policy. Enhanced Image supports classification and policing. Define the traffic classes, scheduling behavior and acceptance checks before specifying the lab unit on the purchase order.
When several legacy switches must share an established administration workflow, CMS can manage a cluster of 16 switches through one IP address. That grouping is a management function rather than additional switching capacity. Identify the command switch, member roles and management connectivity before ordering replacement units.
Gigabit speeds at endpoint ports
The access interfaces stop at 100 Mbps. Gigabit uplink connections do not increase endpoint-port speed, so this model cannot satisfy a Gigabit access-port requirement.
Current Cisco hardware support
The Catalyst 2950 series reached end of support on October 20 2013. Cisco service has ended, so this model cannot meet a currently supported hardware requirement.

WS-C2950G-12-EI identifies a Catalyst 2950 GBIC-uplink model with 12 Fast Ethernet access ports and Enhanced Image software. WS-C2950G identifies the model family, 12 specifies the access-port count, and EI means Enhanced Image. The G model has Gigabit uplinks, not Gigabit endpoint ports.
WS-C2950G-12-EI supports web-based Device Manager or CMS, Cisco Network Assistant, the Cisco IOS CLI through console, SSH or Telnet, SNMP applications, CiscoView, and Cisco Intelligence Engine 2100. These are configuration and monitoring paths. Select the interface and administration software that match the existing legacy management workflow before staging.
WS-C2950G-12-EI is discontinued, and Cisco support for the Catalyst 2950 series has ended. The series end-of-sale date was October 21 2008, and its end-of-support date was October 20 2013. Treat the model as legacy hardware rather than equipment eligible for current Cisco hardware support.
ORM Systems offers WS-C2950G-12-EI new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Cisco's original Limited Lifetime hardware warranty has ended; series support ended October 20 2013.
Yes, WS-C2950G-12-EI supports GigaStack connections with nine switches in a daisy chain. The chain shares 1 Gbps half-duplex bandwidth rather than using dedicated chassis stack ports. GigaStack connections occupy GBIC slots, so account for the interconnect layout and remaining uplink positions when specifying a legacy replacement.
WS-C2950G-12-EI uses two fixed Gigabit GBIC slots supporting copper or fiber connections. The slots accept full-size GBIC transceivers rather than SFPs. Match the transceiver interface, cable connector and remote connection before ordering uplink components; the Gigabit uplinks do not change the Fast Ethernet speed of the access ports.
No, WS-C2950G-12-EI has a fixed internal AC supply rather than a second internal PSU bay. External backup power connects through the RPS connector using PWR300-AC-RPS-N1 or PWR675-AC-RPS-N1=. Specify the external system separately when backup power is required; that connection does not make the chassis a dual-PSU model.
WS-C2950G-24-EI has 24 Fast Ethernet access ports, compared with 12 on WS-C2950G-12-EI. Both models belong to the discontinued Catalyst 2950 family. For legacy replacement purchases, the larger model matches a 24-connection port map, while the smaller model matches an existing 12-port installation. Verify the installed connection count before reserving spares.
WS-C2950G-12-EI includes Enhanced Image, while WS-C2950-12 uses Standard Image. Enhanced Image adds rate limiting and security filtering to the basic software feature set. Both models are discontinued. The Enhanced Image model suits legacy configurations using those additional controls; the Standard Image model matches installations using the basic feature set.
WS-C2950T-24 has two fixed copper Gigabit uplinks, whereas WS-C2950G-12-EI uses GBIC-based uplinks. WS-C2950T-24 also has 24 access ports rather than 12, and both models are discontinued. The former matches copper-only legacy uplink layouts; the latter matches smaller installations retaining GBIC connections. Confirm both the interface and access-port count before ordering.
