ESD grounding strap
To install a power supply in a QFX3500 device (see Figure 118 on page 363 ):
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 (
OK/!
) LED blinks amber.
3.
Using both hands, place the power supply in the power supply slot on the front panel
of the device and slide it in until it is fully seated and the locking lever slides into place.
