Step 6. Check the Cables and Connect I/O Devices
Cables may loosen during shipping. Check for loose cables before completing the installation. For cabling
illustrations, see Appendix G, “Subsystem Positioning and Cabling”, on page 69. For further details on the
cable descriptions and labels, see Appendix H, “Cabling Information”, on page 81.
Connect any externally attached I/O devices to the I/O subsystems at this time using the following
procedures:
Note: If a display, Universal Serial Bus (USB) keyboard, and a USB mouse were ordered, do the
following. If these components were not ordered, perform steps 4 and 5.
1. Connect the keyboard cable to the Keyboard/Mouse Attachment Card (adapter type N-D).
Note: Use any one of the four ports on the adapter; however, the adapter can support only one
connection at a time.
2. Connect the mouse cable to the USB port on the upper corner of the rear of the keyboard.
3. Attach the display cable to either one of the two ports located on the graphics adapter.
4. Check all blind swap cassettes for broken latches by lightly pushing down on the rear of the handles.
Replace any broken latches.
5. Check to ensure adapters are seated by pushing down on the small metal tab on top of the adapter.
The placement of the graphics adapters and keyboard adapters is described in the PCI Adapter Placement
Reference .
Step 7. Verify that the Unit Emergency Power Off (UEPO) Switch is in
the
Off Position
Note: UEPO refers to the red unit emergency power off switch located on the unit. EPO refers to the
computer room emergency power off.
The unit emergency power off (UEPO) switch is located on the front of the frame of each pSeries 670.
When the switch is tripped, utility power is confined to the machine power compartment. All volatile data
will be lost.
Computer Room Emergency Power Off (EPO)
Attention: When the integrated battery feature (IBF) is installed and the room EPO is tripped, the
batteries will engage and the computer will continue to run. It is possible to attach the computer room EPO
system to the machine UEPO. When this is done, tripping the room EPO will disconnect all power from the
power cords and the IBF backup unit. In this event, all volatile data will be lost.
