5 Finishing Up



This chapter explains important steps to be performed after you replace field- replaceable units (FRUs). Topics covered in this chapter include the following:

Tools Needed

After removing and replacing FRUs, you will need the following tools and materials to finish up:

Removing the Wrist Strap

A wrist strap (or grounding strap) provides grounding for static electricity between your body and the chassis of the system unit. Electric current and voltage do not pass through the wrist strap.

Before you have closed the system unit remove the wrist strap from your wrist and from the metal casing of the power supply in the top of the system unit.

Closing the System Unit

To close the system unit:

    1. Preparation.
      a. Check that there are no loose tools or screws in the unit.
      b. Check that all SBus cards and SIMMs are seated properly.
      c. Check that all cable connections are tight.
      d. Check that the power supply wiring is tucked inside the system to avoid pinching the wiring when you close the system unit.
    2. Grasp the unit top (see Figure 5-1) near the power supply.

    Rotate the unit top at a 15 degree angle and rotate your hand position so that thumbs and fingers point up and the five interlock hooks can be lined up.

Note - The interlock hooks do not engage until the unit is lowered to a 45 degree angle. Continue to hold the cover with your hands.

    3. Reconnect the unit top and bottom.
      a. Rest the front edges together to connect the interlock hooks by pushing gently toward the back of the unit.
      b. As you lower the unit top, continue to push back to secure the connection. The unit top will rest slightly forward.
      c. Push the unit top gently back a few millimeters. As the unit top moves back, the latch buttons should click, securing the unit top to the unit bottom.
    4. Attach the lock block.

    Attach the lock block by inserting the PEM screw through the block on the outside, the security loop on the inside, and into the power supply (see Figure 5-1).

    Tighten the screw with a screwdriver. Be careful not to overtighten the screw.

    5. Power up the system.

    See "How to Turn the Power Back On" later in this chapter.

Reconnecting the Peripherals

To reconnect the External Storage Devices to the system unit:

    1. Reconnect the SCSI cable to the system.

    Reconnect the connector on the SCSI cable to the SCSI port on the system unit's back panel (see Figure 5-2 for the location of the SCSI port).

    2. See the installation guide that comes with your External Storage Device for further instructions.

Reconnecting Cables

Reconnecting the Ethernet Cable

To reconnect the Ethernet cable to the system unit:

    1. Reconnect the Ethernet cable to the back of the system unit.

    See Figure 5-2 for the location of the ethernet port.

    2. Push the slide lock on the system unit to lock the cable to the system.

Video Monitors and Cables

There are several different types of monitors and cabling. The monitors have 13W3 connectors. See the SPARCstation IPX Installation Guide for more specific information on monitors and monitor cables. Part numbers for the various monitors are listed in Appendix B. See Chapter 1 for a list of video monitors.

Mouse Cable

The optical mouse connects to one of two jacks in the back of the keyboard. The mouse can be connected on either the left or right side to accommodate either left-handed or right-handed users. Connect the mouse to the keyboard before you connect the keyboard to the system unit.

Keyboard Cable

A cable connects the keyboard to the system unit. The keyboard port is located at the left rear of the system unit. Connect the keyboard cable on either the left or right side of the keyboard, then to the port on the back of the system unit.

Audio Cable

An audio cable may be connected to the Audio input/output port next to the keyboard/mouse port (see Figure 5-2).

How to Turn the Power Back On

After turning off the power to replace FRUs, turning the power on again is relatively simple.

Warning -

This device is equipped with two 3-wire grounded power cords. To reduce the risk of electrical shock, always plug the power cords into a properly grounded power outlet.

Caution -

Always allow 10 seconds between turning off the power and turning it back on again to prevent possible damage to power supply components in your system unit.

Turn the power switches on in this order:

      a. Monitor
      b. External devices (if you have any)
      c. System Unit

After a minute or so, you should see the login prompt.

When you see the login screen, you can log in to your system. For more information on logging in, see Chapter 1 of the Sun System User's Guide.
