Internal system problems Battery pack problems The battery stops charging or begins to swell The batteries in BBWC battery packs are a consumable material. After 3 years of service, batteries may not provide predictable data retention times. If a battery fails completely, the HP Smart Array controller detects this condition and automatically restricts write cache functions to protect user data. To help ensure uninterrupted performance levels, HP recommends replacing battery packs at 3-year intervals. In NiMH batteries, the charging and discharging processes create and recombine inert gases, which can cause the button cell to swell in size by as much as 20%. Battery packs are designed to stop charging before excess swelling occurs. However, if excess swelling does occur, a pressure mechanism within the button cell releases these non-toxic, non-corrosive gases before the cell incurs physical damage. If this pressure release occurs, the battery no longer charges properly, and the storage solution reports a failed battery. CD-ROM and DVD drive problems System does not boot from the drive Action: 1. Be sure the drive boot order in RBSU is set so that the server boots from the CD-ROM drive first. 2. If the CD-ROM drive jumpers are set to CS (the factory default), be sure the CD-ROM drive is installed as device 0 on the cable so that it is in position for the server to boot from the drive. 3. Be sure no loose connections (on page 20) exist. 4. Be sure the media from which you are attempting to boot is not damaged and is a bootable CD. 5. If attempting to boot from a USB CD-ROM drive: o Refer to the operating system and server documentation to be sure both support booting from a USB CD-ROM drive. o Be sure legacy support for a USB CD-ROM drive is enabled in RBSU. Data read from the drive is inconsistent, or drive cannot read data Action: 1. Clean the drive and media. 2. If a paper or plastic label has been applied to the surface of the CD or DVD in use, remove the label and any adhesive residue. 3. Be sure the inserted CD or DVD format is valid for the drive. For example, be sure you are not inserting a DVD into a drive that only supports CDs. Hardware problems 44

Battery pack problems
The battery stops charging or begins to swell
The batteries in BBWC battery packs are a consumable material. After 3 years of service, batteries may not
provide predictable data retention times. If a battery fails completely, the HP Smart Array controller detects
this condition and automatically restricts write cache functions to protect user data. To help ensure
uninterrupted performance levels, HP recommends replacing battery packs at 3-year intervals.
In NiMH batteries, the charging and discharging processes create and recombine inert gases, which can
cause the button cell to swell in size by as much as 20%. Battery packs are designed to stop charging before
excess swelling occurs.
However, if excess swelling does occur, a pressure mechanism within the button cell releases these non-toxic,
non-corrosive gases before the cell incurs physical damage. If this pressure release occurs, the battery no
longer charges properly, and the storage solution reports a failed battery.
CD-ROM and DVD drive problems
System does not boot from the drive
Action
:
1.
Be sure the drive boot order in RBSU is set so that the server boots from the CD-ROM drive first.
2.
If the CD-ROM drive jumpers are set to CS (the factory default), be sure the CD-ROM drive is installed
as device 0 on the cable so that it is in position for the server to boot from the drive.
3.
Be sure no loose connections (on page
20
) exist.
4.
Be sure the media from which you are attempting to boot is not damaged and is a bootable CD.
5.
If attempting to boot from a USB CD-ROM drive:
o
Refer to the operating system and server documentation to be sure both support booting from a USB
CD-ROM drive.
o
Be sure legacy support for a USB CD-ROM drive is enabled in RBSU.
Data read from the drive is inconsistent, or drive cannot read data
Action
:
1.
Clean the drive and media.
2.
If a paper or plastic label has been applied to the surface of the CD or DVD in use, remove the label and
any adhesive residue.
3.
Be sure the inserted CD or DVD format is valid for the drive. For example, be sure you are not inserting
a DVD into a drive that only supports CDs.
