H164143:  NETFINITY 3500: EMC CLIP REMOVAL TO FIX FLOPPY DRIVE ERROR


 SYMPTOM:

 The following error is displayed when booting the System
 to a bootable floppy diskette or accessing the floppy drive
 from the Operating System:

  "General failure reading drive A"
  "Retry / Abort / Cancel"

 PROBLEM ISOLATION AIDS:

 - The System is any model Netfinity 3500 server Type 8644
   or any model IntelliStation M-Pro Type 6898 configured with
   a Floppy Drive FRU p/n75H9550.

 - The System experiences the Symptoms described under the
   "Symptoms" section of this document.

 - The Floppy Drive Cables are properly connected.

 FIX:

 The EMC Clip responsible for the Floppy drive failure
 has been removed from the Systems presently manufactured.

 WORKAROUND:

 Remove the EMC (electromagnetic compatibility) clip
 connected to the 3.25" DASD Cage below the Floppy Drive as
 follows:

 1-Power-Off and disconnect all peripheral devices connected to
   the System, then disconnect the System power cord.

 2- Remove the Floppy Drive (refer to the Users Manual or the
    HMM section: "Installing or removing Internal drives")

 3- Locate the copper colored EMC clip located and attached
    to the inside of the bottom of the DASD cage the Floppy
    drive was located. The Clip will be positioned at center
    from the sides and one third from the front of the cage.

 4- Remove the EMC clip using needle nose pliers. Removal will
    only require a average pull on the EMC clip.

 5- Re-install the Floppy Drive (refer to the User's Manual
    or the HMM as in step 2).

 6- Re-connect the System power cord, and peripheral devices,
    power-on the peripheral devices, then power-on the System.

 7- Access a known good diskette from the Operating System or
    boot the System from a bootable diskette to verify proper
    operation of the Floppy Drive.

 DETAILS:

 The Floppy Drive may fail if the EMC clip exerts pressure on
 the motor spindle of the drive.
