Installing the PCI32-VME64 Adapter
2–2 DIGITAL PCI32-VME64 Adapter Hardware Owner's Guide
2.3 Mechanical Requirements
2.3.1 Dimensions
VMEbus Bridge Module Dimensions: 160 mm x 233 mm (6.3 in. x 9.2 in.)
VMEbus Bridge Module weight 120 g (4.2 oz)
PCI Bus Bridge Module Dimensions 106.68 mm x 312 mm (4.2 in. x 12.28 in.)
PCI Bus Bridge Module weight 120 g (4.2 oz)
2.3.2 Installation Restrictions
The following restrictions apply to the PCI32-VME64 adapter hardware:
•
Installation of the PCI32 module in a PCI slot, which supports shared interrupts, is not
supported.
•
Installation of the PCI32 module in a PCI slot, which is behind a PCI-PCI bridge chip
(i.e. secondary PCI bus), is not supported.
•
Due to the tightly integrated nature of the module set, power to the VME64 module must
remain on while the host operating system is running. Powering off the VMEbus chassis
while the host operating system is running will result in a system crash.
2.3.3 Installing the Adapter
This section provides the steps necessary to install the adapter modules.
_____________________________Caution__________________________
Electrostatic discharge may cause the PCI32-VME64 adapter to malfunction.
When you handle adapters, wear an antistatic wriststrap with the wire clipped to
the frame of the system.
______________________________________________________________
1. Perform a power shutdown of both the VMEbus chassis and the AlphaServer system.
a. Perform an orderly shutdown of the operating system.
b. Set all power switches on the system and the VME chassis to the “off” position.
c. Unplug all power cords from the wall socket, then disconnect the cord from the
system unit and the VME chassis.
2. Set jumpers on the VME and PCI modules to the desired configuration settings, as
outlined Section 1.4.6 and Section 1.4.7.
3. The PCI bus bridge adapter module is shipped with the straight extender bracket
attached. The type of extender bracket required depends on the model of the AlphaServer
host. Table 2-2 identifies the PCI extender bracket used in each AlphaServer model. If
the AlphaServer system requires a slot-offset extender bracket, remove the straight
extender bracket and refer to Figure 2-1 to install the PCI slot-offset extender bracket.
