BRAND NEW FACTORY SEALED & RETAIL BOXED WITH THE FULL JUNIPER WARRANTY!!!
Juniper 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.
