To install a power supply in a QFX5200 (see
1. Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
2. Taking care not to touch power supply components, pins, leads, or solder connections, remove the
power supply from its bag.
CAUTION: Verify that the direction of the arrow on the power supply handle matches
the direction of airflow in the chassis. Ensure that each power supply you install in the
chassis has the same airflow direction. If you install power supplies with two different
airflow directions, Junos OS raises an alarm, and the status (ALM) LED blinks amber.
3. Using both hands, place the power supply in the power supply slot on the FRU panel of the switch
and slide it in until it is fully seated and the locking lever slides into place.
