Uplink Modules in EX4500 Switches

EX4500 switches support SFP+ uplink modules. The SFP+ uplink module is a hot-insertable and hot-removable field replaceable unit (FRU).

Note: Uplink modules and transceivers are not part of the EX4500 switch’s shipping configuration. You must order them separately.

You can install up to two SFP+ uplink modules in an EX4500 switch. Both uplink modules install horizontally on the front of the chassis. The uplink module slot on the left is PIC 1. The uplink module slot on the right is PIC 2. See Figure 1.

Each SFP+ uplink module provides four ports. Each module can house four 10-gigabit small form-factor pluggable (SFP+) transceivers or four 1-gigabit small form-factor pluggable (SFP) 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 when new transceivers are installed in those ports.

The operating mode for an SFP+ uplink module is shown in the output of the show chassis pic fpc-slot slot number pic-slot 1 command.

You can use the uplink module ports to connect an access switch to a distribution switch.

Figure 2 shows the SFP+ uplink module.

The SFP+ uplink module has an LED on the faceplate (labeled ST) that indicates the status of the uplink module. See Figure 2.

Table 1 describes the LED on the uplink module in an EX4500 switch.

Each uplink module port has a pair of LEDs that indicate the link/activity and status of the port. See Network Port and Uplink Module Port LEDs in EX4500 Switches for details about the uplink module port LEDs.

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

The SFP+ uplink modules require Junos OS for EX Series switches, Release 9.4 or later.
