To replace a Cisco Nexus 7004 fan tray, follow these steps:
Step 1 Place an antistatic mat or antistatic foam where you can place two fan trays (the new fan tray and the one
that you will remove from the switch).

Step 4 Grab the fan tray handle with one hand and pull the fan tray part way out of the chassis.
Step 5
Place your other hand under the fan tray to support its weight, pull the fan tray out of the chassis, and
place it on the antistatic pad or repack it in the shipping materials.
Step 6 Grab the handle of the replacement power supply with one hand, place your other hand under the fan
tray, and align the fan tray to the fan tray bay in the chassis.
Step 7
