Replacing fan trays
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."
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.
NOTE
Maintain all power supply and fan assemblies in operational condition to provide redundancy.
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.
CAUTION
Changes or modifications made to this device that are not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
