FIGURE 66 Exhaust Power Supply with Green Label
Time and Items Required
Installing or removing and replacing a power supply should require less than five minutes to complete.
A new power supply (with the same airflow direction as the power supply being replaced) is required to replace a power supply.
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.
Inserting a New AC Power Supply
Use the following steps to install an AC power supply (the 400 watt or 1200 watt power supply) in the RUCKUS ICX 7550 switch.
