Installing/removing a fan tray
CAUTION:
•
Install two fan trays of the same model on the switch. Do not power on the switch when it does not have
fan trays or has only one fan tray installed.
• Make sure slots are installed with fan trays or blank filler panels for the device to operate.
• If both fan trays fail during operation, replace them within 2 minutes while the switch is operating.
• If one fan tray fails, perform either of the following tasks:
{
If the ambient temperature is not higher than 27°C (80.6°F), replace the fan tray within 24 hours and make
sure the failed fan tray is in position before the replacement.
{
If the ambient temperature is higher than 27°C (80.6°F), replace the fan tray immediately.
Only the S5560-30F-EI, S5560-30C-EI, S5560-54C-EI, S5560-30C-PWR-EI, S5560-54C-PWR-EI, and
S5560-54QS-EI switches support hot-swappable fan trays.
The switch comes with empty fan tray slots. Choose the fan tray models based on the ventilation
requirement of the site. The air flow direction varies by fan tray model.
• The LSPM1FANSA has a blue handle and provides power-to-port air flow.
