Chapter 1 Overview The AlphaServer GS80 systems form the low end of the family of highperformance server platforms GS80/160/320 designed for enterprise-level applications. Like the GS160/320 systems, the GS80 systems are distinguished by their versatility and high degree of expandability. This chapter gives an overview of the GS80 system with a block diagram and a physical diagram. Section 1-4 lists the system and expander cabinets with their power requirements.
1.1 The System The GS80 systems come in two Alpha microprocessor configurations: 4-processor and 8-processor. Each group of four microprocessors, along with memory and I/O modules, is designed into a single quad building block (QBB) that is housed in a drawer. Thus the systems are also designated as one-drawer and two-drawer.
System Upgrades A system upgrade is achieved in three ways: • Adding a second drawer to a single drawer system • Adding a storage device to the single-drawer system • Adding an expander cabinet to accommodate any additional I/O devices This manual details the procedures for the addition of a second drawer to the system cabinet as well as the installation of a PCI box. The addition of an expander cabinet is discussed in the AlphaServer GS80 Installation Guide (EK-GSR80-IN).
1.2 GS80 Block Diagram Figure 1–2 shows a block diagram of a two-drawer GS80 system. A distribution board makes the interconnect between the two drawers (QBBs) through their global ports.
1.3 GS80 Physical Diagram Figure 1–3 shows the physical diagram of a two-drawer GS80 system with a PCI box and an optional storage unit.
1.4 Cabinets Table 1–1 shows the model number of cabinets and power requirements for GS80 systems operating in various electrical environments.

The SRM console prompt (P00>>>) is displayed at the end of power-up. This completes the power-up initialization/testing sequence. The operating system can be booted and installed from the SRM console prompt. Follow instructions given in the AlphaServer GS80/160/320 User’s Guide to: • Set boot options • Boot and install Tru64 UNIX • Boot and install OpenVMS You can now run Q-VET to verify the system installation (Section 4.4).
4.4 Q-VET Installation Verification Run the latest Q-VET released version to verify the system installation. Compaq recommends running the latest Q-VET released version to verify that hardware on Tru64 UNIX and OpenVMS systems is installed correctly and is operational. Q-VET is the Qualification Verifier Exerciser Tool that is used by product engineers to exercise systems under development. Q-VET does not verify the operating system configuration.
Q-VET must be de-installed upon completion of system installation verification. Do not leave this software at a customer site; misuse may result in loss of customer data. Swap or Pagefile Space The system must have adequate swap space (on Tru64 UNIX) or PageFile space (on OpenVMS) for proper Q-VET operation. You can set this up either before or after Q-VET installation.
4.4.1 Installing Q-VET The procedures for installation of Q-VET differ between operating systems. You must install Compaq Analyze and Q-VET on each partition in the system. TCP/IP (on Tru64 UNIX) or DecNet_Phase IV (on OpenVMS) should be configured before installing Q-VET. Compaq Analyze must be installed on each partition. Q-VET will not start if Compaq Analyze is not installed. Install and run Q-VET from the SYSTEM account on VMS and the root account on UNIX.
VET. After the installation completes, you should delete the output directory with rm -r output. You can also delete the kit tar file. 8. You must reboot the system before starting Q-VET. 9. On reboot you can start Q-Vet GUI via vet& or you can run non GUI (Command Line) via vet -nw OpenVMS 1. Delete any QVETAXPxxx.A or QVETAXPxxx.EXE file from the current directory. 2. Copy the self-extracting kit image file (QVETAXPxxx.EXE) to the current directory. 3.
4.4.2 Running Q-VET You must run Q-VET on each partition in the system to verify the complete installation. Compaq recommends that you review the Testing Notes section of the Release Notes before running Q-VET. Follow the instructions listed under your operating system to run Q-VET in each partition. Choose the Long IVP script rather than the Short one. Tru64 UNIX Graphical Interface 1.
OpenVMS Graphical Interface 1. From the Main Menu, select IVP, Load Script and select Long IVP (the IVP tests will then load into the Q-VET process window). 2. Click the Start All button to begin IVP testing. Command-Line Interface $ vet /int=char Q-Vet_setup> execute ivp.vms Q-Vet_setup> start Note that commands are case sensitive. NOTE: A quick IVP script is provided for a simple verification of device setup. It is selectable from the GUI IVP menu, and the script is called .Ivp_short.scp (ivp_short.
4.4.3 Reviewing Results of the Q-VET Run After running Q-VET, check the results of the run by reviewing the Summary Log. If you run Q-VET as instructed, Q-VET will terminate testing after the slowest test has completed one pass and produce a Summary file. The termination message will tell you the name and location of this file. All exerciser processes are terminated automatically when the RunTime expires or manually via the Terminate command.
4.
4.4.4 De-Installing Q-VET The procedures for de-installation of Q-VET differ between operating systems. You must de-install Q-VET from each partition in the system. You must de-install Q-VET from each partition. Failure to do so may result in the loss of customer data at a later date if Q-VET is misused. Follow the instructions listed under your operating system to de-install Q-VET from a partition.
Appendix A GS80 Interconnection Diagram Figure A–1 shows the interconnection diagram of the GS80 system. Use this diagram as a guide for cabling when doing system upgrades.

Appendix B Upgrades Using B4166 and B4168 CPUs Upgrading original systems depends upon whether the customer decides to retain the older, slightly slower CPUs or not. There are three types of upgrades: • Adding CPUs to a (black) system that always had B4166 CPUs. • Replacing B4125 CPUs in a (blue) system with B4166 or B4168 CPUs. • Adding B4166 or B4168 CPUs to a (blue) system containing B4125 CPUs.
B.1 Upgrades Retaining Older CPUs These upgrades consist of adding new CPUs, and possibly, a new system drawer. See Chapter 2 for procedures on how to add a new system drawer. Figure B–1 shows how to install a CPU. Table B-1 describes the different CPUs. The CPU derives its operating clock speed from the system clock. The B4125 CPU is not supported when the system clock is run at 9.0 ns. NOTE: Be sure to update the firmware. See Section B.2.
1. Check the firmware revisions and update, if necessary. 2. Ensure that the color code of the CPU module matches the color code of the slot. 3. Push the retainers on the module latches with your thumbs in the direction of the arrows and release the latch. 4. Slide the module into the slot guide and gently push it in until the latches are activated. 5. Close the latches onto the bulkhead and push them in until you hear one or two clicks. The module is now firmly seated in the slot.
Table B– 1 Comparison of CPUs (Continued) CPU Part Number B-cache Size Speed in MHz B4168 Uses 4 of its 16 MB B-cache 1148 The B4168 runs at this speed when placed in a QBB that supports only 4 Mbytes of B-cache, when all CPUs in the system are B4168 or B4166, and the clock runs at 9.0 ns. Uses 8 of its 16 MB B-cache 1001 The B4168 runs at this speed and uses 8 Mbytes of its B-cache when the B4168 is placed in the same QBB as the B4166 and the clock is at 9.0 ns.
From outside the drawer, there is no easy way to visually distinguish between the two system drawers; to see the components that differ requires looking inside the drawer. The best way to determine which drawer is in the system is to use the show fru command. The 54-class part number is listed on the QBBx line when the show fru command is issued from either the SCM monitor or the SRM console. Configuration Rules The original (blue) system upgrade is governed by the following rules: 1.
B.2 Upgrades Replacing Older CPUs First, update the system firmware and then replace the old CPU(s). See Figure B– 1. Finally, change the speed of the system clock. Example B– 1 Updating the Firmware P00>>> show config Compaq Computer Corporation Compaq AlphaServer GS80 6/731 SRM Console PALcode V5.8-1, built on May 26 2000 at 12:15:01 OpenVMS PALcode V1.81-1, Tru64 UNIX PALcode V1.75-1 Micro Firmware V5.
Issue the SRM show config command. Note the version of the SRM console. The B4166 requires V6.0-514 or higher, and the B4168 requires V6.3 or higher. Note the firmware revision of the microprocessors. The B4166 requires V6.0-514 or higher, and the B4168 requires V6.3 or higher. Issue the SCM command to get to the SCM monitor. Only necessary if the system is partitioned. Issue the set hp_count 0 command if the system is partitioned.
B.3 Changing the Clock Module Switch Settings Two switch packs on the clock module control the clock frequency. If no B4125 CPUs are in the system, the clock can run at the faster speed (9.0 ns). Figure B– 2 System Clock Switch Packs 52.2 MHz/9.6 ns S1 S2 1 2 3 4 S2 1 S1 0 1 2 3 4 5 6 0 1 55.6 MHz/9.
The switch packs on the master clock control the speed of the system. When B4125 CPUs are in the system, the clock runs at 9.6 ns. To set the system speed to 9.0 ns, access the clock module and change the switches.
1. Access the top system drawer and remove CPU3 and memory 2 to allow space to access the clock module. 2. Remove the clock module cover plate in the rear left corner of the drawer compartment by removing the two Phillips head screws holding it in place and lift it out of the drawer. 3. Remove the clock compartment shield. Note how the shield is installed. 4. Unplug the coax clock cable(s) from the clock module. 5. Unplug the power cable. 6.
B.4 B4168 Compatibility Switch The B4168 CPU module has a switch that must be set if the module is to be used with B4125 modules in the same QBB. Figure B– 4 Setting the B4168 Switch For use with B4168 or B4166 CPUs For use with B4125 CPUs S1 Switch Power Converter CPU Chip MR0489 Figure B–4 shows the location of the S1 switch that must be changed if the module is to be in a QBB with a B4125 module.
B.5 Verification When you power up the system, check that the SCM correctly maps the QBBs in the system. Execute the SRM set sys_serial_num command. Run Q-Vet (see Section 4.4.2).
B.6 Replacing the System Cosmetics After a system is completely upgraded, new cabinet doors, sides, and top may be installed.
Door Removal 1. 2. If the door has a service pouch on it, remove it and place it inside the cabinet. 3. Disconnect all cables to the OCP. 4. Remove the outer screw of the upper bracket holding the door to the frame. 5. Loosen the inner screw of the upper bracket and slide the door and bracket to let the screw pass through the bracket. 6. Tilt the door away from the cabinet and lift it off the bottom bracket. Open the front door and remove the screw at the cabinet end of the ground strap.
