Working with Adapters (Netfinity 7000-M10 - Type 8680)
Working with Adapters
You can add adapters to extend the capabilities and power of the server.
Many adapters provide bus-master capabilities, which enable the adapters to perform
operations without interrupting the server's microprocessors.
You add adapters to the expansion connectors, called slots, on the I/O board of the server.
All slots are peripheral component interconnect (PCI) expansion slots.
The server supports up to 12 adapters in the PCI slots.
You can install a new PCI adapter or replace an existing PCI adapter with the same type of
adapter without turning the server power off and restarting the system.
These slots are called hot-pluggable PCI slots. They are also
referred to as hot-plug PCI slots.
Hot-plug requires support from both the operating system and the adapter device driver.
A PCI adapter comes with built-in identification and configuration specifications
(set in memory on the device) that provide installation information to the server during
startup.
This information is read by the input/output (I/O) bus and interpreted by the server BIOS.
The BIOS routines automatically configure the adapter around the resources already in use by other devices.
The server comes with a video controller. This video controller is an integrated component on the I/O function card.
The integrated video controller has super video graphics array (SVGA) technology.
The integrated video controller is not removable.
If you want to disable this controller and use a video adapter instead, you can install a video adapter in an expansion slot.
When you install a PCI video adapter, the server BIOS automatically disables the integrated video controller.
The integrated video controller has 1 MB of video memory.
The integrated video controller supports the following screen resolutions:
- 640 x 480 pels with up to 65,536 colors
- 800 x 600 pels with up to 65,536 colors
- 1024 x 768 pels with up to 256 colors
- 1152 x 864 pels with up to 256 colors
The following illustration shows the location of the expansion slots and other components
referred to in these steps.
- I/O function card slot
- Power LEDs
- Attention LEDs for PCI slots
- Hot-plug 32-bit PCI slots 11-12 (bus C)
- Hot-plug 32-bit PCI slots 6-10 (bus B)
- Hot-plug 64-bit PCI slots 1-5 (bus A)
LEDs for PCI Slots: Each PCI slot has three lights
associated with it - two Attention lights and one Power On light.
- Power On Light: This light is on when the PCI slot is active and has power.
Do not add or remove an adapter from the PCI slot when the Power On light is on.
When this light is off, the PCI slot is inactive and has no power applied.
You can install or remove an adapter when the Power On light is off.
Refer to the operating system documentation to determine if it supports hot-plug PCI adapters.
- Attention Lights: Each PCI slot has two Attention lights: one that
is visible from the rear of the server and one that is visible inside the server.
(The lights have the same meaning, they are duplicated to be visible from outside or inside the server.)
An Attention light flashes approximately once per second when it is on.
The meaning of the Attention lights is defined by the operating system.
Refer to the operating system documentation to determine if it supports hot-plug PCI adapters and, if so,
what the Attention lights indicate.
