PCI Cards
Keep the following points in mind when removing or installing a PCI card:
■
All slots accept short or long PCI cards.
■
33-MHz slots accept 5V PCI cards; 66-MHz slots accept only 3.3V cards.
■
All slots accept either 32-bit or 64-bit PCI cards.
■
All slots comply with PCI Local Bus Specification Revision 2.2.
■
All slots accept universal PCI cards.
■
Each slot can supply up to 15 watts of power. The total power used for all six
slots must not exceed 90 watts, in any combination of 5-volt and/or 3.3-volt
cards.
■
Compact PCI (cPCI) cards and SBus cards are not supported.
■
You can improve overall system availability by installing redundant network or
storage interfaces on separate PCI buses. For additional information, refer to the
Netra 440 Server System Administration Guide (817-3884-xx).
Note –
A 33-MHz PCI card installed in to any of the 66-MHz slots causes that bus to
operate at 33 MHz.
Note – All internal devices, except hard drives, must be installed only by qualified
service personnel.
The part number for the PCI card will vary, depending on the card. Contact your
local Sun service representative for more information.
Removing a PCI Card
Caution – The system supplies power to the PCI card even when the system is
powered off. To avoid personal injury or damage to the system, you must disconnect
all AC or DC power cables before servicing the PCI card.
1. Power off the system.
See “Powering Off the System” on page 26 .
