Catalyst 3550 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: Some Catalyst 3550 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.
