• Replacement power supply or a cover panel for the power supply slot
The power supplies in an EX4100 switch are hot-removable and hot-insertable field-replaceable units
(FRUs) installed in the rear panel of the switch. If two power supplies are installed, you can remove and
replace them without powering off the switch or disrupting switch functions.
NOTE: If only one power supply is installed in the switch, you must power off the switch before
removing the power supply.
CAUTION: We recommend that you install either a replacement power supply or a
cover panel in the empty power supply slot to prevent chassis overheating and dust
accumulation.
To remove a DC power supply from the switch (see
):
1.
Place the antistatic bag or the antistatic mat on a flat, stable surface.
2.
Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD point on the
chassis.
3.
Make sure that the voltage across the DC power source cables leads is 0 V and that there is no
chance that the cables might become active during the removal process.
4.
Remove the two screws that attach the terminal connector to the power supply socket.
5.
Remove the terminal connector from the power supply unit.
6.
Slide the ejector lever toward the left until the power supply is unseated.
7.
Grasp the power supply handle and pull firmly to slide the power supply halfway out of the chassis.
8.
Taking care not to touch power supply pins, leads, or solder connections, place one hand under the
power supply to support it. Grasp the power supply handle with your other hand and pull the
power supply completely out of the chassis.
9.
Place the power supply in the antistatic bag or on the antistatic mat placed on a flat, stable surface.
