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 10.

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 uplink module 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 11 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 11.
