Catalyst 2950/2955 Connectors and Cables
Identify the switch chassis part number. Use this table in order to match up the part number with the type of
connector and cable used.
Note: This guide does not cover the Catalyst 2950 Long-Reach Ethernet (LRE) Switches. Refer to Long-
Reach Ethernet Products for more information on cabling and specifications.
Note: Some Catalyst 2950 switches support the GigaStack GBIC, which requires a Cisco proprietary cable
of either CAB-GS-50CM (0.5-meter cable) or CAB-GS-1M (1-meter cable). Refer to Catalyst GigaStack
Gigabit Interface Converter Switch Compatibility Matrix for a list of switches that support the GigaStack
GBIC.
