Extreme Networks ExtremeSwitching SLX 9540 - Identifying the Airflow Direction; Times and Items Required; Replacing a Fan Assembly; Inserting a New Fan Assembly

Identifying the airow direction
The power supply and fan assemblies are identied by the following airow 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.
– Nonport-side air intake
– Port-side air exhaust
– Back-to-front (nonport-side to port-side) airow
– Part numbers ending with -R
• 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.
– Nonport-side air exhaust
– Port-side air intake
– Front-to-back (port-side to nonport-side) airow
– Part numbers ending with -F
Times and items required
Installing or removing and replacing a fan assembly should require less than
ve minutes to complete.
The following items are required to replace a fan assembly:
• New fan assembly (must have the same airow direction as the fan assembly being replaced)
• #1 Phillips screwdriver
Replacing a fan assembly
When installing or replacing a fan assembly unit, keep in mind the following:
• Fan assemblies can be swapped in or out while the device is running. The remaining fan assemblies provide enough airow for
the device.
• The airow direction of the fan assembly must match that of the installed fan trays. All must be either exhaust or intake.
CAUTION
Ensure that the airow 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."
