Identifying The Airflow Direction - Extreme Networks ExtremeSwitching SLX 9140 Hardware Installation Manual

DANGER
If the installation requires a different power cord than the one supplied with the device, make sure you use a power cord
displaying the mark of the safety agency that defines the regulations for power cords in your country. The mark is your
assurance that the power cord can be used safely with the device.
CAUTION
Disassembling any part of the power supply and fan assembly voids the warranty and regulatory certifications. There are no
user-serviceable parts inside the power supply and fan assembly.
CAUTION
Ensure that the airflow direction of the power supply unit matches that of the installed fan tray. The power supplies and fan
trays are clearly labeled with either a green arrow with an "E", or an orange arrow with an "I."
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.

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.
