Ports for the Cisco Nexus 3048 Switch
The Cisco Nexus 3048 switch chassis includes the following ports:
• 10/100/1000 Ethernet downlink ports (48 ports)
• 1- and 10-Gigabit Ethernet uplink ports
• 100/1000 Ethernet management ports (2 ports)
• Console port (1 port)
• USB port (1 port)
The chassis has 48 10/100/1000 Ethernet downlink ports that you connect to servers, which are often in
the same rack or a nearby rack. You use RJ-45 connectors with copper cables to connect the switch to
the servers. The ports are numbered from left to right from 1 to 48 with the odd-numbered ports on top
and the even-numbered ports on the bottom.
You use up to four 1- and 10-Gigabit Ethernet uplink ports to connect the switch to one to four hosts or
switches. You use an SFP or SFP+ transceiver for each of these ports.
Two 100/1000 Ethernet management ports enable you to manage switch operations. You can connect to
the switch through these two ports by using an RJ-45 connector on a copper cable.
One console port enables you to initially configure the switch and to perform troubleshooting operations.
You use an RJ-45 connector with a copper cable to connect to this port.
One USB port enables you to save or load switch configurations.
