Chapter 8 Removal and Installation Procedures
Replacing a Cisco Nexus 7010 Fabric Fan Tray
Step 1 Place an antistatic mat or antistatic foam where you can place the fan trays.
Choose a place that prevents damage to the module while it is outside the chassis.
Step 2 Place the replacement fan tray on the antistatic mat or antistatic foam.
Step 3 Loosen the two captive screws on the fan tray that you are replacing by turning them counterclockwise
until they are free of the chassis.
Step 4 Grasp the fan assembly with both hands, and pull it outward. If the fan tray power connector does not
easily unseat from the backplane, rock it gently.
Step 5 Pull the fan assembly clear of the chassis, and place it on an antistatic mat or antistatic foam.
Step 6 Hold the replacement fan tray so that the fans are on top and the fan status LED is on the right.
Step 7 Place the replacement fan tray into the open slot for a system fan tray. When it is aligned with the left
and right chassis guides for the fan tray, push the fan module into the chassis until the power connector
seats in the backplane and the captive screws are aligned to their holes in the chassis.
Step 8 Tighten the captive screws to 8 in-lb.
