AM-6060 Service Manual Page 1 INTRODUCTION The instructions in this document are intended only for authorized service personnel. AM-6060 computers contain a high-output power supply, which produces current levels high enough to make it unsafe for unauthorized persons to perform work inside the chassis.
Page 2 AM-6060 Service Manual Figure 2: Chassis Top Cover Removal ELECTRONIC EQUIPMENT HANDLING PRECAUTIONS With the AC power cord unplugged and the top cover removed, the components inside your computer are vulnerable to damage caused by static discharge. Your body and clothing can store an electrical charge that can damage or destroy unprotected electronic components. Before handling any computer hardware, make sure your work area is properly protected against static discharge.
AM-6060 Service Manual Page 3 Figure 3: Static Protection Wrist Strap BOARD VERSIONS AND COMPATIBILITY Only certain versions of the AM-176 CPU board can be used in the AM-6060. Specifically, the AM-176 must be Rev. C04 or later, with boot PROMs (DWB-00176-10) Rev. B00 or later. The front panel display board in the AM-6060 must be the AM-966-10. No other front panel display board is supported.
Page 4 AM-6060 Service Manual HARDWARE CONFIGURABLE OPTIONS The following sections summarize the configuration options available to let you tailor your hardware to your needs. These options require access to the main circuit boards inside the computer, and should be performed only by qualified technical personnel. Contact your VAR if you need assistance.
AM-6060 Service Manual Page 5 The only two field-configurable jumpers are: • JP4: the optional remote reset cable attaches to the left pin here. See page 7. • JP5: when installed, pressing the Turbo button on the front panel places the computer into the Level7 diagnostic state. See the LEVEL7 User’s Guide for instructions on how to proceed when the computer is in Level7. In addition, the AC power fail connector attaches to JP6.

AM-6060 Service Manual Page 7 Remote Reset Capability The AM-301-10 board has an option to enable the computer's remote hardware reset, using a special cable from Alpha Microsystems, part number DWB-10323-00. To enable remote reset: 1. Connect one end of the cable to JP4 (to the pin nearer J1) on the AM-301-10 board. 2. The other of the cable contains a DB-9F connector; attach this to any unused cutout on the back panel. You will probably have to remove a cover plate on the back panel to do so. 3.

Clean them with alcohol and a cotton swab, if necessary. 5. Insert the edge of the new battery down through the square hole and under the left side of the plastic top. Be sure to install the new batteries with the positive (+) side up. 6.
AM-6060 Service Manual Page 9 WARNING! The SSD chip on the AM-301-10 and the boot PROM on the AM-176 board require a specialized tool for their removal. If you attempt to remove the SSD chip or boot PROM using a screwdriver or pocketknife, you could easily damage both the chip and the socket. This type of chip extraction tool is available at retail stores specializing in electronic components.
Page 10 AM-6060 Service Manual The AM-966-10 board uses the following connections and jumpers: Location J1 JP1 JP2 JP3 JP4 JP5 JP6 * Description 26-pin cable to AM-301-10. Notice pin 1 orientation on Figure 8. Connects to Turbo switch. Connects to Reset switch. In an AM-6060, this jumper must be on the upper two pins (those closest to J1). To speaker and front panel power. Connects to system activity (Turbo) light. Place connector on left two pins (white goes on center pin).
AM-6060 Service Manual Page 11 Installing the External Cache SIMM The external cache SIMM must only be installed in the J1 slot, labeled CACHE SIMM. Never install memory expansion SIMMs in J1, or the cache SIMM at any other location. To install the 64KB external cache SIMM (PDB-00701-00) on the AM-176 board: 1. Align pin 1 on the external cache SIMM module with pin 1 on connector at J1. Pin 1 on the SIMM module is on the notched end of the module (see Figure 9 below). 2.
Page 12 AM-6060 Service Manual The cache SIMM will engage the retainer clips and click into position, locking in place. When properly installed, the components on the cache SIMM module will be facing in toward the other memory SIMMs. Installing Memory SIMMs The AM-6060 supports a minimum of 8MB and a maximum of 512MB of main memory. Memory is implemented as paired SIMM modules (of equal capacity) of 4MB, 8MB, 16MB, 32MB, 64MB, or 128MB each. Use 60ns SIMMs only; 70ns SIMMs will not work.
AM-6060 Service Manual Page 13 To install memory expansion SIMMs on the AM-176 board, use this procedure: 1. Memory SIMMs must be installed in pairs of equal capacity. 2. Always install the SIMMs of largest capacity first. 3. Always install the first pair of SIMM modules at Bank0. Use Bank1 for a second pair of SIMM modules. 4. Insert the first SIMM in connector J2. Align pin 1 at the notched end of the SIMM module with pin 1 on the connector, as shown in Figure 9. 5.

Page 16 AM-6060 Service Manual 1. Remove the two Phillips-head screws attaching the panel to the chassis. Notice how the panel is positioned over the two alignment tabs on the bottom of the chassis. When you reinstall the panel, you must make sure it is properly positioned over both tabs; if not, you won’t be able to reinstall the two screws. 2. Tilt the top of the panel away from the chassis and remove it. 3.
