Use care when handling the fan trays. Never handle the fan tray by its connector.
Improper handling of fan trays could cause damage to the connector pins.
Perform the following steps:
1.
Press the hot swap button on the fan tray front panel. The blue hot swap LED
blinks.
The ShMC will shut down the fan tray. The ShMC may also increase the speed of the
other fan tray to compensate for the deactivated fan tray.
2.
Wait 60 seconds for the fan tray’s impeller to stop spinning. Do not rely on the
hot swap LED to indicate readiness for removal because the fan tray’s hot swap
LED stops blinking before the impeller stops spinning.
If you remove the fan tray while the impeller is still spinning, gyroscopic forces can
cause the fan tray to move in unexpected ways. This may injure you directly or cause
you to drop the fan tray, which may damage the equipment.
3.
Release the locking screw that secures the fan tray to the shelf.
