Adapters - (NF 8500R - Type 8681)


You can add adapters to extend the capabilities and power of the server.

You add the adapters to the expansion connectors, called slots, on the I/O board of the server.
All slots are PCI expansion slots. The server supports up to 12 adapters in the PCI slots.
There are two additional dedicated slots for the I/O function card and the Advanced System Management PCI adapter.

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.

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 following illustration shows the location of the expansion slots and other components referred to in these steps.


-1- Midplane connector
-2- I/O function card slot
-3- Voltage regulator module (VRM) connectors
-4- Advanced System Management PCI adapter slot
-5- USB 1 and USB 2 port connectors
-6- PCI switch card connector
-7- Hot-plug, 64-bit, PCI slots 10-12 (bus A, 33 MHz)
-8- Hot-plug, 64-bit, PCI slots 8-9 (bus B, 66 MHz)
-9- Hot-plug, 64-bit, PCI slots 6-7 (bus C, 66 MHz)
-10- Hot-plug, 64-bit, PCI slots 1-5 (bus D, 33 MHz)

-11- Hot-plug external attention/fail LED for PCI slot
(green blink = attention, amber = defective PCI adapter)

-12- Hot-plug internal attention/fail LED for PCI slot (green blink = attention, amber = defective PCI adapter)

-13- Hot-plug power LED for PCI slot (green solid, on)

PCI slot LED descriptions: Each PCI slot has two lights associated with it - one Attention/Fail light and one Power On light.

Adapter considerations: Before you continue with the adapter-installation procedure:

Table 1 contains information on the requirements for the PCI adapter slots and PCI buses in the server.

Table 1. PCI adapter information 

Bus Slots Speed PCI slot
A 10-12 33 MHz 5.0 V
B 8-9 66 MHz 3.3 V
C 6-7 66 MHz 3.3 V
D 1-5 33 MHz 5.0 V


  1.  All expansion slots are hot-plug, 64-bit, PCI slots.
  2.  You can install:
    1.  A full-length or half-length, 32-bit or 64-bit, 5 V or Universal,
       hot-plug or non-hot-plug PCI adapter in slots 1-5 or 10-12.
       66 MHz PCI adapters plugged into these slots will operate at 33 MHz.
    2.  A full-length or half-length, 32-bit or 64-bit, 3.3 V or Universal,
       hot-plug or non-hot-plug PCI adapter in slots 6-7 and 8-9.
       A 33 MHz PCI adapter installed in one of these slots limits a 66 MHz
       PCI adapter installed on the same bus to 33 MHz.
  3.  To optimize performance, spread the installation of high-speed adapters,
     such as 66 MHz Ethernet adapters, between the two 66 MHz PCI buses.

Configuring adapters: PCI devices automatically communicate with the server configuration information.
This usually results in automatic configuration of a PCI device.
From the Configuration/Setup utility program, you can select available resources for the adapter that you are installing.
If a conflict does occur, see 'Resolving configuration conflicts'.

Refer to the documentation that comes with the adapter for information about required system resources.
Then, make the appropriate jumper or switch settings on the adapter.
