Juniper Power Supplies & Fans for EX Switches
According to Juniper, EX4100, EX4400 and EX4650 switches feature redundant hot-swappable power supplies and field-replaceable fans. Additional power supplies increase availability and, on PoE models, the available PoE budget.
Power supplies and fans are available with front-to-back or back-to-front airflow and in some cases as DC versions. The airflow direction must match the device and the rack ventilation. According to the datasheet, Juniper covers EX Series power supplies and fan trays under warranty for five years.
We are happy to advise you on project and volume enquiries. On request, DEVACON takes care of planning, configuration and commissioning.
