PROBLEM DESCRIPTION:
Customers and Field Service Representatives that install X-option
add-on disk drives or who are replacing an existing internal Ultra
Enterprise 450 drive FRU, (described above) may experience a problem
with the seating of the newly installed disk drive(s).
Reports of this problem are very sparse, however, if the seating
problem is encountered, the following symptom will be apparent after
the internal disk drive(s) has been installed:
1. The "probe SCSI" command will NOT reveal the target ID of the newly
installed disk drive.
2. The green LED that corresponds to the installed disk drive will NOT
be illuminated.
Currently this problem appears to be related to a backplane flexing
problem which results in the disk backplane flexing away from the drive
connector upon insertion, thus causing the disk drive(s) not to be seen
with the probe-scsi-all command.
IMPLEMENTATION:
---
| | MANDATORY (Fully Pro-Active)
---
---
| | CONTROLLED PRO-ACTIVE (per Sun Geo Plan)
---
---
| X | REACTIVE (As Required)
---
CORRECTIVE ACTION:
Customers and Field Service Representatives that install X-option
add-on disk drives or who are replacing an existing internal Ultra
Enterprise 450 drive FRU can avoid the above mentioned internal disk
drive seating problem by following the drive installation recommend-
ation shown below:
1. Open the bottom door.
This door covers the lower part of the system's front panel and is
hinged on the left side. Unlock the door, if necessary, pull firmly
on the right side of this door and swing it out and to the left.
2. Align the drive with its drive bay opening.
If you are installing the drive as a new option, install it in the
lowest available slot number. Verify that a disk backplane is
installed behind the selected drive bay.
Orient the drive so that the handle's hinge is on the left and the
handle is open (extended). Slide the handle latch to the right to
open the handle.
3. Fit the drive into the guide rails on each side of the drive bay.
4. Slide the disk drive into the drive bay until the handle contacts
the disk cage.
5. Swing the drive handle closed until it latches.
NOTE. After the drive handle is closed and latched, give the drive
and extra push to ensure that full contact of the connectors is
achieved.
Closing the handle engages the drive with it's backplane connectors.
If the system power is on, the green LED beside the disk slot will
light to indicate that the drive is properly inserted.
Repeat steps 2 through 5 for any other drives that need to be
replaced.
COMMENTS:
For additional information on the installation of internal drives
on the E450 please reference the Ultra 450 Workstation Owner's
Guide.
