Replacing the AT-SBx31FAN Tray
The AT-SBx31FAN Tray can only be replaced in the vertical chassis slot
located on the right side of the AT-SBx3112 Chassis.
Note
Before replacing the fan, it is recommended that you disable the AT-
SBx31FAN Tray in the Switchblade x3112 Management Software.
This will stop the fan alarms from being sent to network
administrators during the replacement period.
Caution
The AT-SBx31FAN Tray contains active electronic devices, which
can be damaged by electro-static discharges (ESD). Follow the
procedure given in “Protection Against Electrostatic Discharge
(ESD)” on page 64 to guard against ESD damage when unpacking
and installing this line card.
Caution
Each of the line cards require that air actively flows across the
electronic circuits for proper operation. Ensure that the fan tray is
installed before powering any line cards.
Perform the following procedure to replace the AT-SBx31FAN Tray:
Removing the existing AT-SBx31FAN Tray from the chassis.
Installing a new AT-SBx31FAN Tray in the chassis.
