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.

Choose from the following options:
- If you are using an HMC Version 6 or earlier, continue with step 2.
- If you are using a an HMC Version 7 or later, continue with step 3.
Use the Specifications for HMC to help ensure that you position the HMC in the correct location. Then continue with step 4.
Ensure that you position the HMC in the correct location. Then continue with step 4.
Choose from the following options:
- If you are installing a rack-mounted HMC, continue with step 5.
- If you are installing a stand-alone HMC, continue with step 6.
Perform the following steps to install a rack-mounted HMC:

2. Install the HMC into a rack. When you are finished installing the HMC into a rack, continue with the next step.
3. Choose from the following options:
  - If you are using an HMC Version 6 or earlier, continue with step 5.d.
  - If you are using a an HMC Version 7 or later, continue with step 5.f.
4. Connect the monitor, keyboard, and mouse:
  For connection to a model 7310-CR2 HMC, connect the keyboard and display to the C2T-to-KVM (keyboard, video, mouse) adapter breakout cable that you have previously attached to the HMC. The mouse is integrated with the keyboard.
  
  If you are using a stand-alone monitor, keyboard, and mouse, read the following:
  - For connection to a model 7310-CR2 HMC, connect the keyboard and display to the C2T-to-KVM (keyboard, video, mouse) adapter breakout cable that you have previously attached to the HMC. If your keyboard and mouse use USB connections, you can also connect them to the USB ports on the front panel of the HMC.
  - For connection to a model 7310-CR3 HMC, connect the keyboard, display, and mouse using the USB conversion option cable.
5. Continue with step 7.
6. Connect the keyboard, display, and mouse using the USB conversion option cable.
7. Continue with step 7.

If you are installing a stand-alone HMC, perform the following steps:

Use the following illustrations to identify the location of the connectors described in these instructions:

Attach the monitor cable to the monitor connector, and tighten the screws.
Attach the power cord to the monitor.
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.
Plug the power cord into the HMC.
Connect the keyboard and mouse:
- USB connections: Connect the keyboard and mouse to 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.
  Note: If you are using a stand-alone model 7310-C01 or 7310-C02 HMC, connect the keyboard and mouse to the front-panel USB ports only.
- PS/2-type connections: Connect the mouse and keyboard to their connectors on the back panel of the HMC.
- Universal Serial Bus ports: Connect the keyboard and mouse to 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.

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:
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.
Connect the Ethernet (or crossover) cable from the HMC to the managed server:
Note:
- In general, your HMC should be connected to the managed server in a private service DHCP network; specifically, your HMC connection to the 9118-575 server and the 590 and 595 servers must be made 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 to complete the following instructions. To find the location of these ports, refer to the illustrations.
  - If you have installed additional Ethernet adapters in the PCI slots, see Identifying the Ethernet port defined as eth0 to determine which Ethernet port you must use.
- 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 as your installation progresses.
- Connect the Ethernet port on the HMC to the Ethernet port that is labeled HMC1 on the managed server. On the model 9118-575 server and the 590 and 595 servers, use the port labeled J00A on the front bulk power control assembly.
  If you are connecting a second HMC to your managed server, connect to the Ethernet port that is labeled HMC2 on the managed server; on the 9118-575 server and the 590 and 595 servers, use the port labeled J00A on the rear bulk power control assembly.
If you use an external modem, plug the modem power supply cord into the HMC modem.
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.
If you are setting up the HMC to manage a new server, go to Cabling your server. Click Select by model and choose the model server you want to cable. Next, select the console you are using, and complete the remaining steps in that checklist.
If you are setting up the HMC to manage an existing server, continue with Preparing for HMC configuration.
