Verify that the AC and DC LEDs on each power supply are lit green.
8.
If the amber fault LED is lit, remove power from the power supply, and replace the
power supply (see "Removing a Power Supply from a QFX10002" on page
not remove the power supply until you have a replacement power supply ready: the
power supplies or a blank cover panel must be installed in the switch to ensure proper
airflow.
CAUTION: Replace a failed power supply with a blank panel or new power
supply within 1 minute of removal to prevent chassis overheating.
The power supply in a QFX10002 is a hot-removable and hot-insertable field-replaceable
unit (FRU). You can remove and replace it without powering off the switch or disrupting
switch functions. You do, however, need to remove power from the power supply before
attempting to remove the unit.
WARNING: DC-powered QFX10002 models are intended for installation only
in a restricted access location.
Before you begin connecting DC power to the switch:
Ensure that you have taken the necessary precautions to prevent electrostatic discharge
(ESD) damage (see "Prevention of Electrostatic Discharge Damage" on page
Ensure that you have connected the switch chassis to earth ground.
CAUTION: Before you connect power to the switch, a licensed electrician
must attach a cable lug to the grounding and power cables that you supply.
A cable with an incorrectly attached lug can damage the switch (for
example, by causing a short circuit).
