Power supply removal and replacement

Replacing a power supply
Complete the following steps to replace a power supply in a Brocade 6520. Refer to Figure 10 for
this procedure.
1. To leave the Brocade 6520 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. Unplug the power cord from the power supply that is being replaced.
3. Push the locking tab to the left and hold it there while using the handle on the power supply to
pull it straight out and away from the chassis. Pull the power supply out slowly to avoid catching
a finger on the locking tab.
4. Slide the new power supply into the chassis until the locking tab engages.
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.
CAUTION
If you observe that the switch has powered down after two minutes after a power supply
replacement, it is likely because the new power supply has a mismatched airflow.
5. Plug the power cord into the power supply to power on the unit.
If the power circuit was on before the replacement, the power supply will immediately attempt
to power up.
