Juniper Networks EX3200, EX4200 manual XFP Uplink Module

Complete Hardware Guide for EX3200 and EX4200 Ethernet Switches

■SFP transceivers are supported in all four ports.

The ports that support SFP+ transceivers are labeled 10 G on the uplink module’s faceplate (see Figure 25 on page 35).

NOTE: When an SFP+ uplink module is operating in 10-gigabit mode:

■Only the 10-gigabit ports (ports 0 and 2) are enabled.

■You can use only SFP+ transceivers in those ports.

When an SFP+ uplink module is operating in 1-gigabit mode:

■All four ports are enabled.

■You can use only SFP transceivers in all four ports.

The SFP+ uplink module has an LED on the faceplate (labeled Operating mode LED in Figure 25 on page 35) that indicates the operating mode. If the uplink module is operating in the 10-gigabit mode, the LED is lit. If the uplink module is operating in the 1-gigabit mode, the LED is unlit.

SFP+ uplink modules are shipped with dust covers preinstalled in the ports.

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, a corresponding network port from the last four built-in ports is disabled. For example, if you install an SFP+ transceiver in port 2 on the uplink module (ge-0/1/3), then ge-0/0/23is disabled.

The disabled port is not listed in the output of show interface commands.

The SFP+ uplink module requires JUNOS Software for EX Series switches, Release 9.4 or later.

XFP Uplink Module

Figure 26 on page 37 shows the XFP uplink module, which provides two ports for 10-gigabit XFP transceivers.
