Questions & Answers
What is the Juniper JPSU-650W-DC-AFI power supply?
The JPSU-650W-DC-AFI is a 650-watt DC power supply module designed for Juniper networking platforms, featuring front-replaceable unit (FRU) installation and side-to-side airflow from the FRU side to the port side.
What are the key specifications of the 650W DC power supply?
It delivers 650 W of DC power, supports –40 V to –72 V input, operates at 90%+ efficiency, and provides side-to-side airflow cooling to maintain optimal thermal performance.
Which Juniper devices are compatible with JPSU-650W-DC-AFI?
This power supply is compatible with select Juniper EX and QFX Series switches equipped with DC power supply bays that accept FRU modules with side-to-side airflow.
What does FRU side-to-port side airflow mean?
FRU side-to-port side airflow indicates that cooling air enters through the replaceable power supply side (FRU side) and exits toward the switch port side, ensuring consistent chassis ventilation.
How do I install the JPSU-650W-DC-AFI in my chassis?
Power off the chassis, slide the module into the empty DC bay until it clicks, secure the latch, then reconnect the DC input cables and power on for automatic recognition.
Is the JPSU-650W-DC-AFI hot-swappable?
Yes, the JPSU-650W-DC-AFI supports hot-swap replacement without downtime when installed in a chassis with at least one other active power supply.
What DC input voltage range does it require?
The module accepts a DC input range of –40 V to –72 V, making it suitable for standard telco and datacenter power infrastructures.
How can I verify that the power supply is functioning correctly?
Check the front-panel LED: solid green indicates normal operation, amber warns of a noncritical condition, and red denotes a critical fault requiring attention.
Does this power supply support redundancy?
Yes, the JPSU-650W-DC-AFI can operate in n+1 redundancy configurations when multiple identical DC modules are installed in the same chassis.
What cooling features are included in the JPSU-650W-DC-AFI?
It incorporates an internal variable-speed fan and side-to-side airflow design to maintain optimal temperatures under full load.
How do I monitor the power supply status remotely?
Use Junos OS CLI or Juniper Network Director to view real-time DC input voltage, output power, fan speed, and temperature readings.
What safety and regulatory certifications does it hold?
The JPSU-650W-DC-AFI is UL, CE, C-Tick, and FCC certified, and meets RoHS and WEEE environmental compliance standards.
What is the mean time between failures (MTBF) for this power supply?
The typical MTBF for the JPSU-650W-DC-AFI exceeds 200,000 hours at 25 °C ambient temperature under full load conditions.
How much acoustic noise does the power supply generate?
Under normal operation, acoustic noise remains below 50 dBA, ensuring minimal disruption in standard datacenter environments.
What operating temperature range does it support?
The module is rated for an operating temperature range of 0 °C to 40 °C (32 °F to 104 °F) and a storage range of –40 °C to 70 °C (–40 °F to 158 °F).
What warranty does Juniper provide for the JPSU-650W-DC-AFI?
Juniper offers a limited lifetime warranty covering defects in materials and workmanship, with optional extended support contracts available.
