Adapters



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 microprocessor.

You can install up to seven adapters in the expansion connectors, called slots, on the system board of the server. Six of the slots are peripheral component interconnect (PCI) expansion slots and one is an industry standard architecture (ISA) expansion slot.

Four of the PCI slots allow you to 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, if these features are supported by the operating system. These slots are called hot-pluggable PCI slots. They are also referred to as hot-plug PCI slots.

The expansion slots have Plug and Play capabilities. See 'Plug and Play Technology' for additional information.

The server comes with a video controller. This video controller is an integrated component on the system board. It is not in an expansion slot. 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. When you install an ISA video adapter, you must move a jumper to disable the integrated video controller. See 'System Board Jumpers' for more information.

The following illustration shows the location of the PCI and ISA expansion slots on the system board.
 

32 16-bit ISA slot
34 Power LEDs for hot-swap slots
34 Attention LEDs for hot-swap slots
35 Hot-plug 32-bit PCI slots 1-4
36 Non-hot-plug 32-bit PCI slots 5 and 6


LEDs for Hot-Plug PCI Slots: Each hot-plug PCI slot has three LEDs associated with it - two Attention LEDs and one Power LED.


The following table describes the LEDs:

Power LED Attention LED Description
On Flashing The adapter required attention.
Slot has still power applied.
Do not remove or install an adapter in the slot.
Refer to the operating system documentation for
instructions.
On Off Normal operation, no intervention is required.
Off Flashing The adapter requires intervention.
Power is removed from the slot.
An adapter can be removed or installed in the slot
Off Off Power is removed from the slot.
An adapter can be removed or installed in the slot
