CHAPTER 15
Maintaining the Fan Module for Cisco cBR
• Removing the Fan Module from the Cisco cBR Chassis, on page 187
Removing the Fan Module from the Cisco cBR Chassis
Before you begin
Attach an ESD-preventive wrist strap to your wrist.
Restrictions
• Only one fan module should be removed at a time for servicing or replacement.
Ensure that all Fan Module bays must have functioning Fan Modules. If a Fan
Module is removed, replace a functioning Fan Module within one minute of the
removal, to avoid possible shutdown of the system due to overheating of individual
components.
Warning
• Do not operate the chassis with an empty fan bay even if the Supervisor Card allows it.
• Cisco cBR's Supervisor Cards are prevented from powering up if one or more of the Fan Modules have
a serious failure such that the error prevents both fans from operating.
• The chassis powers up even if at least one fan in each Fan Module is working.
Required Tools and Equipment
• A flat-blade screwdriver
Step 1 Loosen the captive screws on the left side of the Fan Module, until the screws are disengaged from the chassis.
Step 2 Pull the fan module from the chassis slightly, grasping the sides of the Fan Module.
Step 3 Grasp the top and bottom frame of the Fan Module with your hand and pull it gently out of the chassis.
