Preparing the system to remove and replace a fan in the EMX0 PCIe3 expansion drawer

Learn how to prepare the system to remove and replace a fan in the EMX0 PCIe3 expansion drawer.

1. Complete the prerequisite tasks. For instructions, see Before you begin.
2. Identify the system that you will be working on. For instructions, see Enabling enclosure or server indicators with the ASMI.
3. If applicable, open the rack front door.
4. Remove the front cover by removing the screws (B) and then pulling the front cover (A) away from the EMX0 PCIe3 expansion drawer by using your fingers. See Figure 1.
   Figure 1. Removing the front cover

   
5. Attach the electrostatic discharge (ESD) wrist strap. Your system has an ESD jack. Plug the ESD wrist strap into the ESD jack that is at the front of the system. See Figure 2.
   Figure 2. Attaching the ESD wrist strap to the front ESD jack

   
6. Locate the fan LEDs. For information about fan LED locations (A) and states, see Figure 3.

   • (B) Indicates that the fan is operating correctly. The green power LED (left LED) is lit solid and the amber fault LED (right LED) is off.
   • (C) Indicates that the fan is not operating correctly. Both the green power LED (left LED) and the amber fault LED (right LED) are lit solid.
   • (D) Indicates the faulty or failed fan was selected by using the identify function. The green power LED (left LED) is lit and the amber fault LED (right LED) is flashing.
7. Determine whether the repair can continue concurrently. To continue the repair concurrently, the following conditions must be true:
   • Fans must be installed in all four slots.
   • If two or less amber fault LEDs are On and parts are readily available, the repair can be completed concurrently.
     Note: Removing and replacing two failed fans is a time sensitive task when serviced with the system power turned on (concurrent). You must replace the first failed fan within 5 minutes after it is removed from the EMX0 PCIe3 expansion drawer. Failure to replace it within 5 minutes can cause the EMX0 PCIe3 expansion drawer to automatically power off.
8. Identify the failed fan by using the identify function. For instructions, see Identifying a part.
9. Select an action.
   • To do a nonconcurrent repair:
     1. Stop the system and the EMX0 PCIe3 expansion drawer. When you stop the system, the EMX0 PCIe3 expansion drawer powers off automatically. For instructions, see Stopping a system.
     2. Remove the failed fan indicated by the flashing amber fault LED (D) shown in Figure 3. For instructions, see Removing a fan from the EMX0 PCIe3 expansion drawer.
   • To do a concurrent repair:
     1. Continue the procedure with the system power turned on.
        Attention: If two of the four fans failed, the first fan that is removed must be replaced within 5 minutes to avoid the EMX0 PCIe3 expansion drawer from automatically powering off.
     2. Remove the failed fan indicated by the flashing amber fault LED (D) shown in Figure 3. For instructions, see Removing a fan from the EMX0 PCIe3 expansion drawer.
