| Step 11| (from step 9 on page 2-2330-12)| Important Notice| Because this step includes a wrap test, it must not be performed under concurrent| maintenance unless the subsystem has adapter microcode ABOVE the level| shown here. Otherwise, unexpected results might occur.| All other types of SSA adapter have microcode that is above the levels shown here.| Adapter Type| Feature Code| ROS Level and ID| 4–D| 6214| 1602| 4–G| 6216| 1603| 1. A diskette that contains adapter microcode of the correct level is supplied with the| Fibre-Optic Extenders. Ensure that the microcode has been installed. Go no further| with these instructions until the microcode is installed. (See 4 on page 2-2330-2| if you need to load the microcode.)| 2. In the next step, you are going to disconnect the fiber optic cables. Before you do so,| note the identifications of the fiber optic cables to ensure that you reconnect them| correctly later.| 3. Disconnect the fiber optic cables 1 from the Fibre-Optic Extender.| 4. Find the wrap cable and adapter assembly that is provided with the Fibre-Optic| Extender.| 5. Remove the wrap cable and adapter assembly from its plastic bag.| 6. If the wrap cable and adapter assembly has a protective cover at each end, remove| those covers.| 7.
