Connectors
and Cabling
• 10BASE-T ports: RJ-45 connectors; two-pair Category 3, 4, or 5 unshielded twisted-pair (UTP) cabling
• 100BASE-TX ports: RJ-45 connectors; two-pair Category 5 UTP cabling
• 1000BASE-T ports: RJ-45; two-pair Category 5 UTP cabling
• 1000BASE-T GBIC-based ports: RJ-45 connectors; two-pair Category 5 UTP cabling
• 1000BASE-SX, -LX/LH, -ZX, and CWDM GBIC-based ports: SC fiber connectors, single-mode or multimode fiber
• Cisco GigaStack GBIC ports: copper-based Cisco GigaStack cabling
• Management console port: 8-pin RJ-45 connector, RJ-45-to-RJ-45 rollover cable with RJ-45-to-DB9 adapter for PC
connections; for terminal connections, use RJ-45-to-DB25 female data-terminal-equipment (DTE) adapter (can be
ordered separately from Cisco, part number ACS-DSBUASYN=)
Power Connectors
• Customers can provide power to a switch by using either the internal power supply or the Cisco RPS. The RPS 300
is compatible with all Catalyst 3550 models except the 3550-24-DC and 3550-24 PWR. The RPS 675 is compatible
with all Catalyst 3550 models except the 3550-24-DC. The connectors are located at the back of the switch
• Internal Power Supply Connector
– The internal power supply is an auto-ranging unit
– The internal power supply supports input voltages between 100 and 240 VAC
– Use the supplied AC power cord to connect the AC power connector to an AC power outlet
• Cisco RPS 675 Connector
– The connector offers connection for an optional Cisco RPS 675 that uses AC input and supplies DC output
to the switch
