AM-7000 Service Manual Page 1 INTRODUCTION This document contains instructions which are intended only for authorized service personnel. AM-7000 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. This document describes the AM-7000 computer package in both the deskside and the AM-990 chassis. It covers the following procedures: • Removing your computer's cover.
Page 2 AM-7000 Service Manual Figure 2: Deskside Chassis Top Cover Removal ACCESSING YOUR COMPUTER (AM-990 AND AM-990 JUMBO CHASSIS) When adding additional equipment or servicing your computer, you will have to gain access to the components inside the computer. To do so, you will need to remove the computer's top cover and side panel. To remove the top cover: 1. Unlock the front door and swing it open. 2. Behind the front door, remove the two screws that connect the top cover to the chassis 3.

Once the top cover slides forward, pull straight up to remove it. To remove the side panel: 1. Remove the four screws that secure the left side panel to the chassis. 2. Using the palm of your hand, firmly strike the rear edge of the side panel. 3.

Most of 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-7000 Service Manual Page 5 AM-319-20 Board Configuration Figure 5 shows the AM-319-20 board configured as shipped by Alpha Micro. There is only one userconfigurable jumper on this board: the JP7 Remote Reset jumper. All other jumpers should be left in their factory configured positions.

AM-7000 Service Manual Page 7 Remote Reset Capability The AM-319-20 board has an option to enable the computer's remote hardware reset. To enable remote reset, you must do two things: 1. Install the JP7 jumper, which is shown in the AM-319-20 illustration (Figure 5). The factory default is not installed. 2. Connect a push-button switch between pin-1 and pin-7 (signal ground) at the terminal end of the terminal cable attached to serial port 0 on the AM-319-20 board.

Use alcohol and a cotton swab to clean them, if necessary. 5. To install a new battery, insert the edge of the 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-7000 Service Manual Page 9 WARNING! The SSD chip on the AM-319-20 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 12 AM-7000 Service Manual PERIPHERAL MOUNTING / CABLE ROUTING (DESKSIDE CHASSIS VERSIONS) Your deskside computer cabinet can hold six half-height peripherals or three full-height 5.25" peripherals. Filler panels in the computer front panel can be removed to allow access to some of these peripherals. If you have six half-height peripherals, four of them can be accessed through the front panel; if you have three full-height peripherals, two of them can be accessed through the front panel. 3.
AM-7000 Service Manual Page 13 A peripheral is installed in the drive mounting bracket using four Phillips-head screws. To install the peripheral mounting screws, you need access to both sides of the peripheral mounting bracket. On one side of the cabinet, all six of the mounting positions are easily accessible. However, on the other side of the cabinet, the AM-319-20 board and its mounting bracket block access to all but the top two mounting positions.
Page 14 AM-7000 Service Manual Side Mounting Bracket Removal Next, you need to unfasten the AM-319-20 side mounting bracket from the deskside chassis. To do so: 1. Remove the two Phillips head screws that secure the AM-319-20's side mounting bracket to the chassis. Before you slide out the board and its mounting bracket, notice how the mounting bracket is positioned over the two alignment tabs on the bottom of the chassis.
AM-7000 Service Manual Page 15 4. With the AM-319-20 assembly out of the way, you will be able to access both sides of the peripheral mounting bracket and have complete access to all six mounting positions. 5. To install a peripheral, simply slide it into one of the available mounting positions in your chassis and install the four screws (two on each side) that hold the device in place. 6. Don't forget to attach the appropriate power and interface cables to your new peripheral. 7.
Page 16 AM-7000 Service Manual PERIPHERAL MOUNTING / CABLE ROUTING (AM-990 AND JUMBO CHASSIS VERSIONS) Mounting peripheral devices in your computer is simply a matter of attaching plastic rails to the side of the peripheral and sliding the device into its mounting position. The AM-990 chassis has mounting locations for 12 half-height (or six full-height) 5.25" peripherals. The front door on the AM-990 chassis has a cutout which allows access to peripheral devices using removable media.
AM-7000 Service Manual Page 17 drives are mounted in the lower part of the chassis for two reasons: to make sure the weight in the chassis is properly distributed and to provide easy access for both power and interface cables. Plastic Mounting Rails The plastic mounting rails are the key to installing peripheral devices in your computer. Two rails are required to mount a peripheral device. The rails (DWF-20652-00) are universal; they can be mounted on either the right or left hand side of the peripheral.
Page 18 AM-7000 Service Manual DWF-20652-00 MOUNTING RAIL Figure 15: AM-990 Attaching Mounting Rails to Peripheral X-Bus Cable Routing You do not need to move either the AM-176-10 or the AM-319-20 board to mount new peripherals, which means you won’t need to disconnect the X-Bus cables. However, if an X-Bus cable should come unplugged from either the AM-176-10 or the AM-319-20 board it is extremely important that the cables are plugged back in correctly.
