We list EX2300, EX3400, EX4100, EX4300 and EX4400 switches and uplink modules, QFX5110, QFX5120 and QFX5200 data center switches, Juniper optics and DAC cables, and EX and QFX power supplies.
Juniper part numbers start with the product family, such as EX4400-48P or QFX5120-32C, and many optics use names like QFX-SFP-10GE-SR. Data center models and their power supplies show airflow in the part number: -AFO for front-to-back and -AFI for back-to-front. Fans and power supplies in one switch must match.
When you buy Juniper equipment, send the exact model, airflow direction and the Junos license tier you need. New, refurbished and used units are available, each with its own warranty in your quote.
