Installing/removing a fan tray

CAUTION:
The switches have only one fan tray slot. To ensure good ventilation, make sure these conditions are
met:
Do not operate the switch without a fan tray.

If the JC692A or JC693A fan tray has problems during operation, replace it within 8 minutes while
•
the switch is operating.
If the JC695A or JC696A fan tray has problems during operation, replace it within 6 minutes while
•
the switch is operating.
If you fail to replace the fan tray within the time limit, the switch generates alarms, the system LED
•
flashes red, and the switch might be damaged.

Selecting a fan tray

The switches provide two types of fan trays with different airflow directions: from power side to port
side and from port side to power side. Before you install a fan tray, check the airflow direction
labeled on the fan tray and make sure the airflow of the chassis is appropriate to the installation site.
When the switch is started up, the system records the airflow direction of the fan tray. After you
replace the fan tray when the switch is operating, if the airflow direction of the new fan tray is not the
same as the old one, the system displays the following trap and log information:
System fan airflow direction is not preferred on slot x, please check it.
If you confirm that the airflow direction of the new fan tray is correct, use the fan prefer-direction slot
slot-number { power-to-port | port-to-power } command in system view to change the preferred
airflow direction.
