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.
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.
11. Verify that the LED on the new power supply displays steady green while the Brocade ICX 6650
is operating (see Table 2 ). If the LED is not steady green, ensure that the power supply is
securely installed and seated properly.
You can enter the show chassis command at the command line prompt to display power supply
status.
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.
Replacing fan trays
CAUTION
For the Brocade ICX 6650 devices, be sure that the airflow direction of the fan tray matches that
of the installed power supply unit. The power supplies and fan trays are clearly labeled with either
a green arrow with an “E”, or an orange arrow with an “I.”
The Brocade ICX 6650 includes two redundant, hot-swappable fan units.
ATTENTION
Maintain all power supply and fan assemblies in operational condition to provide redundancy.
CAUTION
Because the cooling system relies on pressurized air, do not leave any of the power supply and
fan assembly slots empty longer than two minutes while the switch is operating. If a power supply
or fan assembly fails, leave it in the switch until it can be replaced.
