Figure 4–2 shows the XMI configuration rules that apply to systems with
a T2019 power regulator module installed.
1
Slot E of the XMI must be filled for the system to operate. Slot E may
contain a processor or an I/O adapter, but not a memory module.
For systems with VAXBI buses, a DWMBx-A module is typically in this
slot, to be close to a corresponding DWMBx/B module in the VAXBI
card cage.
1
Note that the VAX 6000 Model 600 supports the DWMBA
only when the H9657-CX kit is installed. Other Model 600 systems use
the DWMBB for communication with the VAXBI.
2
The T2019 module is installed in slot 2. Heat sinks on the module
protrude into the space allotted for slot 1. Do not insert the T2019
in any other slot.
3
By convention, install processor modules at slot 3 and proceed to the
left. A maximum of four processors can be installed when you upgrade
using the H9657-CX kit.
4
Memory modules can be placed in slots 3 through D. By convention
in Model 600 systems, memory modules are first placed at slot 9 and
then proceed to the right. Additional memory would then be installed
beginning at slot A and proceeding to the left to slot D.
5
No I/O adapters can be placed in slots 6, 7, 8, and 9.
1
The DWMBx/A and /B modules enable data to be transferred between the XMI and VAXBI
buses.
