1.
Verify that the second power supply has been powered on for at least four seconds, and that the LED
is steady green. This ensures the switch remains in service while replacing a power supply.
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, and use 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 power supply into the chassis. If the power supply does not slide in easily,
ensure that it is oriented correctly before continuing.
• After replacing the power supply, if the switch powers down after two minutes, it is probably
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 was on before the replacement, the power supply will attempt to power up immediately.
