Ports for the Cisco Nexus 3548 Switch
The switch chassis includes the following ports:
• Fixed 1- and 10-Gigabit Ethernet Small Form-Factor Pluggable (SFP+) ports (48 ports)
• 1-PPS timing port (1 port)
• 10/100/1000 management ports (2 ports)
• Console port (1 port)
• USB port (1 port)
The chassis has 48 1- and 10-Gigabit Ethernet ports that you connect to servers, which are often in the
same rack or a nearby rack. You use Small Form factor Pluggable Plus (SFP+) transceivers with copper
or optical 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 useone 1-PPS timing port, with the RF1.0/2.3 QuickConnect connector type.
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 RS-232 serial console port enables you to initially configure the switch and to perform
troubleshooting operations.
One USB port enables you to save or load switch configurations.
