Skip this step if all fan tray slots are already populated with fan trays.
Use the following steps to install a fan tray in any empty fan tray slot.
n
Ensure that a replacement fan has the same airflow as other fan trays installed in the switch (Port-to-Power
or Power-to-Port).

A red-colored fan handle indicates a Port-to-Power air flow. A blue-colored fan handle indicates a Power-to-
Port air flow.
In the event of missing fan trays, misconfigured airflow direction, and/or faulted fans, the switch will try to
maintain adequate cooling by increasing fan speeds and/or disabling misconfigured devices. If adequate cooling
cannot be maintained, the switch will power off for five minutes before rebooting and assessing cooling
capabilities.
Fan trays and power supplies installed in an 8360 switch must have the same cooling air flow direction (port-to-
power or power-to-port). Air flow direction in an 8360 switch is not controlled by software. To change the air flow
direction, replace the power supplies and fan trays with power and fan tray units supporting the air flow direction
required.
For all SKUs (excluding 8360-48Y6C,) a minimum of two working fan trays is required for operation. If fewer than
three working fan trays are detected, the Global status, Rear status, and corresponding Fan Tray LEDs will FLASH
amber. For the 8360-48Y6C, a minimum of four working fan trays is required for operation. If fewer than five
working fan trays are detected, the Global status, Rear status, and corresponding Fan Tray LEDs will FLASH amber.
The system will automatically shut down if overheating is detected.
If one fan tray is missing for more than two minutes the system will shutdown. If two or more fan trays are missing,
the system will shutdown for five minutes and then reboot to reassess cooling capabilities.
System airflow direction (Port-to-Power or Power-to-Port) is configured automatically at system initialization and
cannot be reconfigured by the user. System airflow direction is determined by the power supply type installed in
PS1 at initialization time (or PS2 if PS1 is absent or faulted). Any Fan tray or Power supply of conflicting airflow type
will be disabled by the system. Ensure only matching Fan trays and Power supplies are used at any given runtime.
1. Remove the new fan tray from its packaging, being careful to not touch any of the circuitry on the
board.
2. Insert the new fan tray fully into the slot so that its face plate is flush with the back face of the switch
and the latch clicks.
