Removing a Power Supply from an EX4200 Switch
Ensure that you have the following parts and tools available:
Phillips (+) screwdriver, number 2
An antistatic bag or an antistatic mat
The power supply in an EX4200 switch is a hot-removable and hot-insertable field-replaceable unit (FRU) located on the rear panel of the switch: You can remove and replace it without powering off the switch or disrupting switch functions.
CAUTION:
Do not leave the power supply slot empty for a long time while the switch is on. The power supply must remain in the chassis for proper airflow.
