Powering on an EMX0 PCIe3 expansion drawer

Learn how to power on an EMX0 PCIe3 expansion drawer.

Before you begin, read this entire procedure. If there are procedural steps that cannot be completed now, the procedure must be delayed until a later time.
Attention: If the server is not managed by a Hardware Management Console (HMC), the EMX0 PCIe3 expansion drawer cannot be powered on with the server powered on. To power on the EMX0 PCIe3 expansion drawer without an HMC, power off the server and then power on the server. The EMX0 PCIe3 expansion drawer will power on automatically when the server powers on.
Attention: Do not use this procedure to power on the system unit. To power on a system, see Starting the system or logical partition.

To power on the EMX0 PCIe3 expansion drawer, complete the following steps:

  1. Is your system managed by an HMC?
    • Yes: Continue with step 2.
    • No: To power on the EMX0 PCIe3 expansion drawer without an HMC, you must power on the server. When the server powers on, the EMX0 PCIe3 expansion drawer will power on automatically. For instructions, see Starting the system or logical partition.
  2. If the ac power cords were disconnected when the EMX0 PCIe3 expansion drawer was powered off and you have not reconnected them, reconnect them now. If they are already connected, continue with the next step.
  3. To use the Power On/Off Unit utility from the HMC, choose one of the following navigation options depending on the interface type of the HMC:
    • If you are using an HMC Classic or HMC Enhanced interface, complete the following steps:
      1. In the navigation area, click Systems management > Servers.
      2. To enable the tasks for that server, select the required server name.
      3. From the Tasks menu, click Serviceability > Hardware > Power On/Off Unit.
      4. In the Power On/Off Unit window, expand the managed system and click the appropriate unit.
      5. Click Power On.
    • If you are using an HMC Enhanced + Tech Preview (Pre-GA) or HMC Enhanced+ interface, complete the following steps:
      1. In the navigation area, click the Resources icon Resources, and then select All Systems.
      2. To view the actions for that server, select the server name of the required server.
      3. In the navigation area, select Serviceability > Serviceability.
      4. In the Hardware Operations section of the Serviceability window, select Power On/Off Unit.
      5. In the Power On/Off Unit window, expand the managed system and select the appropriate unit.
      6. Click Power On.
  4. Wait 3 minutes for the I/O resources in the EMX0 PCIe3 expansion drawer to become fully operational.
  5. Reconfigure any I/O resources that were unconfigured when the EMX0 PCIe3 expansion drawer was powered off. Then, go to the next step.
  6. Return to the procedure that sent you here.
