FIGURE 15 Installing an AC power supply unit
1. If replacing a power supply, remove the previously installed power supply from the appropriate
slot by removing the two screws with a Phillips screwdriver.
2. If installing a new power supply into a slot covered with a filler panel:
a. Using a Phillips screwdriver, unscrew the screws on the filler panel.
b. Remove the filler panel.
3. 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.
4. Remove the power supply from the anti-static shielded bag.
5. 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.
6. When you are sure the power supply has properly engaged the connector, tighten the retainer
screws to secure the power supply in the slot.
When the Brocade ICX 7750 is powered on, the LEDs on the power supply back panel should light
up green to confirm that the power supply is correctly installed and supplying power.
CAUTION
Empty fan and power supply slots must be covered using filler panels.
