Replacing a power supply
Complete the following steps to replace a power supply in a Brocade ICX 7750.
1. To leave the Brocade ICX 7750 in service while replacing a power supply, verify that the other
power supply (the one not being replaced) has been powered on for at least four seconds and
has a steady green status LED.
2. Before opening the package that contains the power supply, touch the bag to the switch casing
to discharge any potential static electricity. Brocade recommends using an ESD wrist strap
during installation.
3. Remove the power supply from the anti-static shielded bag.
4. Ensure that the replacement power supply has the same part number and airflow label as the
power supply being replaced.
5. Unplug the power cord from the power supply that is being replaced.
6. Using the Phillips screwdriver, unscrew the two captive screws on the power supply.
7. Remove the power supply from the chassis by pulling the handle on the power supply out and
away from the chassis.
CAUTION
Do not force the installation. If the power supply does not slide in easily, ensure that the power
supply is correctly oriented before continuing.
8. Holding the power supply level, guide it into the carrier rails on each side and gently push it all
the way into the slot, ensuring that it firmly engages with the connector.
9. When you are sure the power supply has properly engaged the connector, tighten the retainer
screws to secure the power supply in the slot.
10. Plug the power cord into the power supply to power on the unit.
The power supply will immediately attempt to power up.
