Cabling the HMC

Connect the Hardware Management Console (HMC) cables, connect the Ethernet cable, and connect the HMC to a power source.

If the physical HMC is not located within 8 meters (25 feet) away from the managed system, you must supply a separate system that can access the Internet using a browser. This system must be within 8 meters (25 feet) of the managed system. This setup allows service personnel remote access to the HMC. The HMC must also be configured to allow for this remote access.
DANGER

  • Connect all power cords to a properly wired and grounded electrical outlet. Ensure outlet supplies proper voltage and phase rotation according to the system rating plate.
  • Connect any equipment that will be attached to this product to properly wired outlets.
  • When possible, use one hand only to connect or disconnect signal cables.
  • Never turn on any equipment when there is evidence of fire, water, or structural damage.
  • Disconnect the attached power cords, telecommunications systems, networks, and modems before you open the device covers, unless instructed otherwise in the installation and configuration procedures.
  • Connect and disconnect cables as described below when installing, moving, or opening covers on this product or attached devices.
    To Disconnect:
    1. Turn everything OFF (unless instructed otherwise).
    2. Remove power cords from the outlet.
    3. Remove signal cables from connectors.
    4. Remove all cables from devices.
    To Connect:
    1. Turn everything OFF (unless instructed otherwise)
    2. Attach all cables to devices.
    3. Attach signal cables to connectors.
    4. Attach power cords to outlet.
    5. Turn device ON.

    (D005)

Use the following instructions to help you cable your rack-mounted or stand-alone HMC.

Attention: Do not plug the power cords into the electrical outlet until you are instructed to do so.
  1. Ensure that you position the HMC in the correct location.
  2. Choose from the following options:
    • If you are installing a rack-mounted HMC, continue with step 3.
    • If you are installing a stand-alone HMC, continue with step 4.
  3. Perform the following steps to install the cables on a rack-mounted HMC:
    1. Use the following illustration to identify the location of the connectors described in these instructions:
      Figure 1. Back view of a typical rack-mounted HMC
      Back view of a rack-mounted HMC. Positions of connectors are shown.

    2. If you are installing your HMC into a rack, see Installing and configuring the Hardware Management Console. When you have finished installing the HMC into a rack, continue with the next step.
    3. Connect the keyboard, display, and mouse using the USB conversion option cable.
    4. Continue with step 5.
  4. If you are installing a stand-alone HMC, perform the following steps:
    1. Use the following illustration to identify the location of the connectors described in these instructions:

      Table 1. Supported HMC ports
      Port Description
      Video The Video port is used as monitor connection.
      PS/2 Keyboard/Mouse A PS/2 keyboard or mouse is not included with the HMC, but you can attach either.
      Serial 1 Serial 1 is supported for an external modem.
      USB These ports are supported for a USB keyboard, mouse, flash memory, or USB diskette drive.
      Ethernet The Ethernet port is used as the HMC's primary network connection.

      The HMC does not support the use of parallel, Serial 2, or systems management Ethernet ports.

    2. Attach the monitor cable to the monitor connector, and tighten the screws.
    3. Attach the power cord to the monitor.
    4. Ensure that the voltage selection switch on the HMC is set to the voltage used in your world region. The voltage selection switch is red and is located near the power connector. Move the switch so that the voltage used in your world region is displayed.
    5. Plug the power cord into the HMC.
    6. Connect the keyboard and mouse to the Universal Serial Bus (USB) ports on the HMC. You can connect the keyboard and mouse to the USB ports on the front or back panels.
  5. Connect the modem:
    Note: During the installation and configuration of the HMC, the modem might automatically dial out as the HMC follows routine call-out procedures. This is usual behavior.

    If you are connecting an external modem, do the following:

    1. Optional: Install the external modem into a rack.
    2. If you have not already done so, connect the modem data cable to the external HMC modem.
    3. Connect the modem data cable to the system port on the HMC labeled with the following symbol:
      Symbol the system port for the RS232 cable
    4. Use the telephone cable to connect the line port of the external modem to the analog telephone jack on your wall.

    If you are connecting to an integrated modem, use the data cable to connect the integrated HMC modem to the appropriate data source. For example, use the telephone cable to connect the HMC modem line port to the analog jack on your wall.

  6. Connect the Ethernet (or crossover) cable from the HMC to the managed server.
    Note:
    • In general, connect your HMC to the managed server in a private service DHCP network. If you have not installed any additional Ethernet adapters in the PCI slots on your HMC, use the primary integrated Ethernet port. Use the previous illustrations to identify the location of the HMC ports.
    • You can verify that the Ethernet cable connection is active by observing the green status lights at both the HMC and managed system Ethernet ports while your installation progresses.
    • Connect the Ethernet port on the HMC to the Ethernet port that is labeled HMC1 on the managed server.

      If you are connecting a second HMC to your managed server, connect to the Ethernet port that is labeled HMC2 on the managed server.

  7. If you use an external modem, plug the modem power supply cord into the HMC modem.
  8. Plug the power cords for the monitor, HMC, and HMC external modem into electrical outlets.
    Note: Do not connect the managed system to a power source at this time.
  9. If you are setting up the HMC to manage an existing server, continue with Preparing for HMC configuration.
    Note: For a complete list of HMC supported external cables, see Serial attached SCSI cable planning topic.
