EX3200 switches support three types of uplink modules:

• SFP uplink module—Provides four ports for 1-gigabit small form-factor pluggable (SFP) transceivers.

  Note: On an EX3200 switch, if you install a transceiver in an SFP uplink module, all the network ports from the last four built-in ports are disabled and remain disabled until you reboot the switch. After rebooting the switch, only the corresponding network port from the last four built-in ports remains disabled, the rest of the network ports are enabled. The disabled port is not listed in the output of the show interface command. For example, if you install an SFP transceiver in port 2 on the uplink module (ge-0/1/2) on 24-port models, then ge-0/0/22 is disabled after you reboot the switch. On an EX3200 switch, if you replace a transceiver multiple times in quick succession in a port that uses fiber-optic connectors, the switch might not create an interface for that port and that port might be disabled. The disabled port is not listed in the output of the show interface command. For example, if you replace an SFP transceiver in port 2 on the uplink module (ge-0/1/2) multiple times in quick succession, then ge-0/1/2 might be disabled.

• SFP+ uplink module—Provides two ports for 10-gigabit small form-factor pluggable (SFP+) transceivers when configured to operate in 10-gigabit mode or four ports for 1-gigabit small form-factor pluggable (SFP) transceivers when configured to operate in 1-gigabit mode.

  Note: On an EX3200 switch, if you install a transceiver in an SFP+ uplink module when the uplink module is operating in the 1-gigabit mode, all the network ports from the last four built-in ports are disabled and remain disabled until you reboot the switch. After rebooting the switch, only the corresponding network port from the last four built-in ports remains disabled, the rest of the network ports are enabled. The disabled port is not listed in the output of the show interface command. For example, if you install an SFP transceiver in port 2 on the uplink module (ge-0/1/2), then ge-0/0/22 is disabled after rebooting the switch.

• XFP uplink module—Provides two ports for 10-gigabit small form-factor pluggable (XFP) transceivers.

Note: When a new uplink module is installed in the switch or an existing uplink module is replaced with another uplink module, the switch detects the newly installed uplink module. The switch creates the required interfaces if the uplink module has transceivers in its ports and when new transceivers are installed in those ports.

When connecting uplink module ports, you can install an SFP uplink module at one end of the connection and install an SFP+ uplink module configured to operate in the 1-gigabit mode at the other end. Likewise, you can install an XFP uplink module at one end of the connection and install an SFP+ uplink module configured to operate in the 10-gigabit mode at the other end.
