Replacing fan trays
CAUTION
For the Brocade ICX 6650 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."
Orderable Brocade ICX 6650 models include 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 slots must be
covered using the filler panels.
ATTENTION
Maintain all power supply and fan assemblies in operational condition to provide redundancy.
CAUTION
Because the cooling system relies on pressurized air, do not leave any of the power supply and
fan assembly slots empty longer than two minutes while the switch is operating. If a power
supply or fan assembly fails, leave it in the switch until it can be replaced.
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.
Determining the need to replace a fan assembly
Enter the show chassis command in the command line interface to display fan status.
