Chapter 4. Location Codes The RS/6000 7046 Model B50 uses physical location codes in conjunction with AIX location codes to provide mapping of the failing field replaceable units. The location codes are produced by the system unit's firmware and AIX. Physical Location Codes Physical location codes provide a mapping of logical functions in a platform (or expansion sites for logical functions, such as connectors or ports) to their specific locations within the physical structure of the platform.
1-C1.1 Identifies CPU 1 on CPU card 1 on planar 1. P2/Z1-A3.1 Identifies a SCSI device with a SCSI address of LUN 1 at SCSI ID 3 attached to SCSI bus 1 from planar 2. P1-I2#E3.2 Identifies the second cable in a series of cables attached to Ethernet controller 3 in slot 2 (I2) on planar 1. Depending on the AIX and firmware levels, AIX Diagnostics may include extended location information when identifing a planar or card.
Name AIX Location Code Location Code Physical Connection Logical Identification SCSI Port 10-80 P1/Z1 J33/J38 Host Bridge ID00, Device 16 Tablet Port 01-Q1 P1/Q1 Card in PCI Slot 2 10-90 P1.1-I2 J3 on Riser Card (Top Connector) PCI Bridge ID01, Device 18 Card in PCI Slot 1 10-b0 P1.
The AB value identifies a bus type or PCI parent bus as assigned by the firmware. The CD value identifies adapter number, adapter's devfunc number, or physical location. The devfunc number is defined as the PCI device number times 8, plus the function number. The EF value identifies a connector. The GH value identifies a port, address, device, or FRU. Adapters and cards are identified with AB-CD.
For async devices, GH defines the port on the fanout box. The values are 00 to 15. For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0. For all other devices, GH is equal to 00. For integrated adapter, EF-GH is the same as the definition for a pluggable adapter. For example, the location code for a diskette drive is 01-D1-00-00. A second diskette drive is 01-D1-00-01.
4-6 7046 Model B50 Service Guide
Chapter 5. Loading the System Diagnostics If no keys are pressed after the server power is turned on, the server searches a list of devices (the default boot list) for a bootable image. If a bootable image is found, then the server loads and starts the operating system. This is called a normal boot. The server can also be booted from a custom boot list, which can be changed through the System Management Services.
If no bootable image is found in the custom boot list, the server restarts and attempts to boot again. If the custom boot list is discovered to be damaged, the server rebuilds the custom boot list according to the default boot list. Loading Diagnostics in Service Mode Boot The server can be booted in service mode (instead of normal mode) from either the default boot list or custom boot list. After a successful service mode boot, the diagnostic programs start automatically.
1. Before stopping the programs and operating system, notify your system administrator and users that the server is going to be shut down. 2. Turn off the server. 3. Wait 30 seconds, then turn on the server. 4. When the keyboard indicator appears during startup, press the F6 key if the system console is a directly attached keyboard, or the 6 key if the system console is an ASCII terminal. 5. Enter any passwords.

Memory Modules You can increase the amount of memory in your system by installing memory modules. Your server uses 168-pin, 3.3 volt, dual inline Error Correcting Code (ECC) memory modules (DIMMs) to increase system memory. You install memory modules into connectors inside the server. You can install up to 1024MB of ECC memory. (1MB equals approximately 1 000 000 bytes.) The memory module sizes for your system include 256MB, 128MB, 64MB, 32MB, and 16MB. The available speed for these memory modules is 60 ns.
4. Remove the memory modules, as shown in the following illustration. 5. Store any memory modules you are no longer using in a static-protective package, as shown in the following illustration. Make a note of the memory module size and speed for future reference. 6. Install any adapters you removed into their original connectors. If you need further information on installing adapters, see “Adapter” on page 7-25. 7.
Replacement 1. Touch the static-protective package containing the option to any unpainted metal surface on the server, then remove the option from the package. 2. Install the first memory module in slot 4, the second in slot 3, and so on. Ensure that the locking tabs are opened prior to installing the memory module, as shown in the following illustration.
3. The memory modules are keyed so that they can only be inserted one way. Align the memory module notches (1 in the following illustration) with the keys in the memory connector. 4. Push down on the memory module until the locking tabs lock the memory module into the connector, as shown in the following illustration. (Do not attempt to move the locking tabs yourself. They lock automatically when you have fully inserted the memory module.
6. Reinstall any adapters you removed into their original connectors. (If you need further information for installing adapters, see “Adapter” on page 7-25.) 7. Go to the Appendix in RS/6000 7046 Model B50 User's Guide and update the system memory information.
