Replacing a Power Supply
When installing or replacing a power supply unit, consider the following:
- Power supplies can be swapped in or out while the device is running. The remaining power supplies provide enough power for the device.
- The airflow direction of the power supply must match that of the installed fan assemblies. All must be either exhaust or intake.
Caution: Power supplies are hot-swappable. However, they should be inserted or removed without
a power cord being connected to a power source to avoid damage.
Caution: Ensure that the airflow direction of the power supply matches that of the installed
fan assembly. The power supplies and fan assemblies are clearly labeled with either
a green arrow with an "E", or an orange arrow with an "I."
Caution: When installing a power supply unit into a switch that has the two-hole grounding
lug, be sure to install the unit in the slot next to the location of the lug screw
holes because a blank plate could interfere with the lug.
