Installing and removing fan trays
Follow these restrictions and guidelines when you install a fan tray:
•
The switch has two fan tray slots: FAN1 and FAN2. Install two fan trays on the switch.
•
To prevent dust from entering the chassis, keep the filler panels or fan trays in position if the
switch is not in use.
•
The fan tray is hot swappable. Follow these guidelines when you hot swap a fan tray:
{
Ensure electricity safety.
{
Replace a fan tray only when the other fan tray is operating correctly.
{
To prevent dust from entering the chassis, keep the failed fan tray in position before the
replacement.
•
To install a fan tray in slot FAN1, orient the fan tray so that the LED is on the left side of the
front panel. To install a fan tray in slot FAN2, orient the fan tray so that the LED is on the right
side of the front panel.
•
To avoid damaging the fan tray, use both hands when installing or removing a fan tray.
•
When you hot swap a fan tray, only one fan tray is operating and it automatically increases the
fan rotation speed and makes louder noise. Take protection measures such as wearing an
earmuff or earplug. In addition, make good preparation before the hot swapping to minimize
the operation time.
