The power supply in J-EX4500 switches 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.
Before you begin removing a power supply from the switch:
Ensure you understand how to prevent ESD damage. See "Prevention of Electrostatic
Discharge Damage on J-EX Series Switches" on page 186.
Ensure that you have the following parts and tools available to remove the power supply
from the switch chassis:
An antistatic bag or an antistatic mat
Replacement power supply or a cover panel for the power supply slot
CAUTION:
Do not leave the power supply slot empty for a long time while
the switch is operational. Either replace the power supply promptly or install
a cover panel over the empty slot.
To remove a power supply from the switch (see Figure 54 on page 129):
Place the antistatic bag or the antistatic mat on a flat, stable surface.
1.
Attach the electrostatic discharge (ESD) grounding strap to your bare wrist, and
2.
connect the strap to the ESD point on the chassis.
