Replacing fan trays
The Ruckus ICX 7450 includes two redundant, hot-swappable fan units. However, it can run on one power supply and one fan. In that
case, the empty power supply and fan slot must be covered using the filler panels.
NOTE
Maintain all power supply and fan trays in operational condition to provide redundancy.
Determining the need to replace a fan tray
Enter the
show chassis

Time and items required
Replacing a fan assembly in the Ruckus ICX 7450 should take less than two minutes to complete.
You need the following items to replace a fan assembly in the Ruckus ICX 7450:
•
A new fan assembly (must have the same part number and the same airflow label as the fan assembly being replaced; refer to
on page 69 for the location of the airflow label)
•
A #1 Phillips screwdriver
Installing or replacing the fan assembly
Complete the following steps to install or replace a fan assembly in a Ruckus ICX 7450.
1.
If replacing a fan assembly:
a.
Using a Phillips screwdriver, unscrew the captive screw on the fan assembly.
b.
Remove the fan assembly from the chassis by pulling the handle on the fan assembly out and away from the chassis.
c.
Ensure that the replacement fan assembly has the same part number and airflow label as the fan assembly being replaced.
CAUTION
For the Ruckus ICX 7450 devices, be sure that the airflow direction of the fan tray matches that of the installed power supply
unit. 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
Because the cooling system relies on pressurized air, do not leave any of the power supply and fan tray slots empty longer
than two minutes while the switch is operating. If a power supply or fan tray fails, leave it in the switch until it can be replaced.
CAUTION
Disassembling any part of the power supply and fan tray voids the warranty and regulatory certifications. There are no
user-serviceable parts inside the power supply and fan tray.
