Uplink Modules in EX4300 Switches

EX4300 switches provide a slot to install an optional uplink module. Uplink modules are hot-insertable and hot-removable field-replaceable units (FRUs).

You can install an uplink module horizontally in the uplink module slot on the front panel of the switch. By installing an uplink module, you add more ports to your switch, thereby increasing the port density of the switch.

Table 37 shows the uplink modules supported on 24-port and 48-port EX4300 switches, their descriptions, and the Junos OS release in which the models were released. Table 38 shows the uplink modules supported on 32-port EX4300 switches, their descriptions, and the Junos OS release in which the models were released.

Note: When you install an uplink module in the switch or replace an uplink module with another uplink module, the switch detects the ports on the uplink module. The switch creates the required interfaces when transceivers are installed in these ports.

The SFP+ uplink module ports can operate either in 10-gigabit or in 1-gigabit mode depending on the transceiver you install in them. The operating mode for an SFP+ uplink module is shown in the output of the show chassis pic fpc-slot slot number pic-slot slot number command.

Each port on the uplink modules has a pair of LEDs that indicate the link activity and status of the port. See Network Port, Built-In QSFP+ Port, Uplink Port, and Uplink Module Port LEDs on EX4300 Switches for details about the status and link activity LEDs.

The SFP+ uplink modules are shipped with dust covers installed in the ports. The QSFP+ uplink module is shipped with a dust cover installed in one of the ports.
