Replacing fan trays
The Ruckus ICX 7750 includes four redundant, hot-swappable fan units. However, it can run on one power supply and three fans. 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.
NOTE
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.

Installing or replacing the fan tray
Complete the following steps to install or replace a fan tray in a Ruckus ICX 7750.
CAUTION
For the Ruckus ICX 7750 devices, be sure that the airflow direction of the fan tray matches thatof 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.”
