Juniper EX4300 Stackable Access Switches - Refurbished, Used, New
Juniper EX4300 switches are stackable campus access and small aggregation switches running Junos. Most models have four 40 GbE QSFP+ ports on the back for Virtual Chassis links, which on supported models can also be used as network ports, plus a slot for an optional uplink module. NetworkTigers sells EX4300 switches, uplink modules, power supplies and fan modules refurbished, used and new; the listing states what is included with each switch. Every unit is tested before it ships so it works when it arrives.

Which EX4300 do I need?
Choose by port type: T for data, P for PoE+, MP for multigigabit PoE, and 32F for fiber aggregation. Then check the uplink module, since each module is supported only on certain models, and the power supply, since the PoE budget depends on which supply is installed. Check the airflow stated in the listing; in the part number, AFI marks back-to-front airflow, and the switch, fans and power supplies should all match. Some listings are DC-powered or TAA versions, shown in the part number. For Virtual Chassis, give us your existing part numbers and Junos release and we will confirm the combination.
Frequently asked questions
Do I need an uplink module?
It depends on the model. On supported models, the 40 GbE QSFP+ ports can be used as network uplinks instead of Virtual Chassis links. On the EX4300-48MP, the built-in QSFP+ ports are Virtual Chassis ports only, so network uplinks come from a supported uplink module. Add a supported module when the built-in network ports do not meet your uplink requirements.
