Page 10: Electrical Equipment Guidelines
Preparing to Unpack the Fan Assembly Module Electrical Equipment Guidelines Follow these basic guidelines when working with any electrical equipment: Before beginning any procedures requiring access to the chassis interior, locate the emergency • power-off switch for the room where you are working. Disconnect all power and external cables before moving a chassis. -
Page 11: Preventing Electrostatic Discharge Damage
Carefully examine your work area for possible hazards such as moist floors, ungrounded power • extension cables, and missing safety grounds. Preventing Electrostatic Discharge Damage Electrostatic discharge (ESD) damage, which occurs when electronic cards or components are improperly handled, can result in complete or intermittent failures. The AC-input power shelf and its AC power modules contain a printed circuit card that is fixed in a metal carrier. -

Page 16: Removing And Replacing The Fan Assembly Module
Removing and Replacing the Fan Assembly Module If you are running a Cisco IOS Release that supports the PRODCUT ID LED/switch feature on the fan Step 7 module (UBR10012-FAN-PLUS=), verify that the PRODUCT ID LED/switch illuminates (green). If you are using the fan module (UBR10012-FAN-PLUS=), and running a Cisco IOS Release that does Note not support the PRODUCT ID LED feature, ensure that the PRODUCT ID LED/switch is not illuminated. - Page 17 Removing the Fan Assembly Module This procedure is applicable to both fan assembly modules (UBR10-FAN-ASSY= and UBR10012-FAN-PLUS=). Note The fan assembly module does not need to be replaced when it is operating normally. If a failure (SINGLE FAN FAIL or MULTI FAN FAIL) LED illuminates (yellow), use the following procedure to remove and reinsert the fan assembly module to test the connection.

Page 23: Troubleshooting The Fan Assembly
Troubleshooting the Fan Assembly Check the following to help isolate a problem with the cooling system: When you start up the system, do the fans start operating? • When the fans are operating, you should be able to hear them. You should also be able to feel air being drawn in at the bottom front and expelled at the top rear of the chassis. -
