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 in which you are working. • Disconnect all power and external cables before moving a chassis. • Do not work alone when potentially hazardous conditions exist. • Never assume that power has been disconnected from a circuit; always check.
Removing and Replacing the Fan Assembly Module The fan assembly module does not need to be replaced when it is operating normally. If a failure LED comes on, use the following procedure to remove and reinsert the fan assembly module to test the connection. If the failure LED is still on after removing and reinserting the module, use the following procedure to replace the fan assembly module. • Single Fan Failure—This yellow LED indicates that one of the four fans in the module has failed.
Remove the Fan Assembly Module Step 1 Remove the front cover by lifting it up slightly and then pulling it toward you (see Figure 2). Step 2 Loosen the captive screws on each side of the fan assembly module. Step 3 Pull the module out of the chassis (see Figure 3 on page 11). Step 4 If you are replacing the cable and the fan assembly module, or if you are replacing just the cable, see the “Replace the Fan Assembly Cable” section on page 12.
Locations of Screws CISCO 10000 CISCO 56293 Figure 3 Install the Fan Assembly Module Step 1 Using two hands, align the new fan assembly module in the slot in the chassis, and push it back firmly. Make sure that the connectors on the can assembly securely connect to the backplane. Step 2 Verify that the FANS OK LED is on (green). If the FANS OK LED is not on or if the FAN FAILURE LED comes on (yellow), try reseating the fan assembly module.
Remove the Cable To replace the fan assembly cable, perform the following steps: Step 1 Remove the front cover. Step 2 Remove the fan assembly. See the “Remove the Fan Assembly Module” section on page 10. Step 3 See Figure 4. Note that the cable has two “U” shaped bends that allow the cable to curve back into the brackets and fit snugly on the bottom of the fan module enclosure.
Step 1 Verify which connector goes in the bracket in the back of the chassis and which connector goes into the front connector. Step 2 Bend the cable in a “U” shape at both ends, to facilitate getting the cable into the rear bracket. See Figure 4 on page 12. Tip Use the existing cable as a template. Step 3 Install the cable in the rear bracket.
• The following messages, if displayed, indicate that the system has detected a critical overtemperature condition or out-of-tolerance power inside the chassis: Queued messages: 00:01:19:%ENVM-4-ENVWARN:+2.5 V measured at +2.59 00:01:19:%ENVM-4-ENVWARN:+5.15 V measured at +5.
