CP210 Addressing Levels
One fault isolation procedure uses the address path to a device, which defines the physical address of each level that is necessary to specify the device. The least complex physical address path is an adapter that transfers information with only one device. Diskette storage, for example, specifies only one level, as the physical address and the device address are the same. As another example, three levels are necessary to specify the device if it is a 3277. The first specifies the adapter physical address, the second specifies the port physical address, and the third specifies the 3277 physical address.
The system configuration determines the number of physical address levels needed to specify a particular device or adapter. The most complex physical address path occurs when the adapter has multiple groups each having multiple station adapters, and each station has multiple 1/0 devices. This example specifies four physical address levels;
adapter, group, station, and device.
As shown in Figure CP210-1, the addressing level does not depend on device type, but rather on how the device connects to the 8100 system. For example, a 3276 connected by a data I ink is a level 02, but a 3276 connected to a loop is a level 03. These levels are specified when building the system configuration table, and are the parameters that specify the path to the device when running tests. The last level specified becomes the level under test.
After specifying the last entry in a test level request, the single character entry immediately following specifies whether: (1) the hardware associated with the last physical address level entry is tested, (2) all devices associated with that physical address level are tested, or (3) the initial test entry message is displayed to select another physical address path.
Note: Online operation permits testing only one physical address path for each test entry. Concurrent analysis occurs only when using off/ ine tests.
Specific areas contain the physical address path configuration information:
• The configuration tables on the MD diskettes contain the path information when using the MD.
• The environment profile contains the path information when using DPPX online tests.
• The test control monitor configuration table contains the path information when using DPCX.
The path information on the MD diskettes must be identical to that contained in the assigned path information area for the operating system. If the customer performs hardware configuration changes, you must update the configuration tables on the MD diskettes to agree with these dlanges, or test errors could result.

CP220 Fixed Addressing Assignments
This section describes the fixed addressing assignments on the 8100, which are used for:
• All adapters.
• All communications ports.
• The primary and secondary system control facilities.
• Channel request priorities (feature-dependent).
• Programmed 1/0 operations.
Also, this section enables you to:
• Convert any DPCX logical address (LA) or primary communications adapter (PCA) address to a physical address.
• Relate any physical address to its associated hardware component and location, MAP and corresponding reference material designation, and MD diskette used for testing.
CP221 SSCF Address Switches
Each SSCF (SC5) card contains hardware switches whose binary setting specifies a hexadecimal address used for programmed 1/0 operations. These address assignments are the same as the physical addresses (PAs) used for system information transfer (see CP223). As in physical addressing, this value defines the SSCF and the device attached to it. For example (see CP222), to transfer information with communications port 1 on the first 8101, the PIO address, as well as the physical address is 10. The first digit specifies the first 8101 (1) and the second digit specifies the first communications port (0).

CP224 DPCX Addressing Conversion Reference
LA or PCA PA
DPCX system messages identify the failing component as either a logical address (LA) or a primary communications adapter (PCA) address. In some cases, the LA or PCA equals the physical address (PA); in others the LA or PCA must be converted to a PA.
Use the DPCX SYSLDEV Utility (see CP851) to identify the devices listed in the DPCX configuration table area. Use it also to identify the adapter address of an 8809 tape drive, as well as which 32XX device is attached to a downstream control unit.
The following chart lists the PA values for any DPCX LA or PCA.

CP230 How Devices Attach to the 8100
IBM machine types attach to an 8130, 8140, or 8101 by using either a Facility for Attaching Communications (FAC) number group, or another IBM machine type attached to a FAC. For example, the 2502-A1 attaches only to a 3782-2, which can attach only to a 3289-3. The 3289-3, in turn, can attach only through F ACs 10 or 11. Refer to the chart below for the methods of device attachment for an 8100 system.
Note: This chart does not attempt to show the features needed for device attachment.
Refer to Chapter 4, GR220, for such information.
