2.9 IBM Netfinity 7000 Power and Cooling
The IBM Netfinity 7000 Server chassis is divided in two parts. The upper part
contains the system board and its components. Three hot-swap cooling fans
provide cooling redundancy, which means that the server can continue to operate
even if a fan fails. Nevertheless, the failing hot plug fan should be replaced as
soon as possible to regain the cooling efficiency and maximum reliability.
The chassis part below contains the power components, the hot-swap drive bays,
the backplanes and the expansion bays. The cooling there is provided by cooling
fans attached to the hot-swap power supplies.
The Netfinity 7000 comes standard with two 400 watt hot-swap power supplies to
support full configurations. Operating the Netfinity 7000 with only one power
supply is not allowed.
The optional IBM Netfinity 400 watt Hot-Swap Redundant Power (#94G7150) can
be added to allow the IBM Netfinity 7000 Server to operate without interruption if
one of the two standard power supplies fails. The replacement of the failing power
unit (easily removed and reinstalled) will be possible without powering down the
server.
When three power supplies are installed in the system, the power load is shared
across all three sources. You won’t need any additional power cables.
2.10 BIOS and Firmware Level
It is important to apply the latest firmware and BIOS updates. This can help you
to save a lot of time wasted searching for errors and fixing problems. See the
driver and update list in 2.1, “Drivers and Updates” on page 17 for the drivers,
BIOS and firmware revisions that are required during this installation.
2.10.1 Netfinity 7000 System BIOS Update
During the boot process, the current BIOS version installed on your Netfinity 7000
is shown on the screen in the upper left corner and on the front panel display. You
can also check it with the System Configuration Utility (SCU). The SCU can be
started from the Netfinity 7000 System CD-ROM or from the SCU diskette.
For example, the current Netfinity 7000 BIOS Version 14 is shown as:
The BIOS upgrade also provides new BIOS versions for the on-board Ultra
Fast/Wide SCSI controller.
