Technical data

When adding a device to a system, you must know the capacity of the

system enclosure in these areas:

1. Number of backplane slots

2. Power supply capacity

3. Mass storage device space

4. AC and DC loading

1.15.4 Module Order and Conﬁguration

Module order in the backplane is speciﬁc, depending on the CPU. Refer to

the applicable CPU maintenance manual for the preferred module order of

a given system.

For information on how to conﬁgure modules, refer to Microsystems Options

(EK–192AC–MG), which includes a listing of all supported options along

with the following information for each module and device:

• Ordering information

• Operating system support

• Diagnostic support

• Option description

• CSR addresses and interrupt vectors

• LEDs

• Loopback connectors

• Self-tests

• FRUs (if applicable)

• Related documentation

1.15.5 Conﬁguration Worksheets

Use Figure 1–21 or Figure 1–22 to be sure your conﬁguration does not

exceed system limits for expansion space, power, and bus loads. If you use

standard Digital modules, you will not exceed the limits for bus loads.

When changing a conﬁguration, choose one of the worksheets that applies

to your system.

1. On the worksheet, list all the devices already installed in the system.

2. List all the devices you plan to install in the system.
