Power Supplies
Identifying the airflow direction
DRAFT: BROCADE CONFIDENTIAL
Identifying the airflow direction
The power supply and fan assemblies are identified by the following airflow directions:
•
Intake power supply and fan assembly with an orange "I" label or without any label
: Pulls air from the nonport-side of the
switch and exhausts it out the port side.
•
Exhaust power supply and fan assembly with a green "E" label
: Pulls air from the port side of the switch and exhausts it out the
nonport-side.
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, keep in mind the following:
•
Power supplies can be swapped in or out while the device is running. The remaining power supply provides 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
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in place. If you run the chassis with
an uncovered slot, the system will overheat.
