Acer RM900 Installation Manual

Installation Guide 1 1 Getting Started Unpack the rack and check the packing list that came with it. Make sure that you have all components. The unit of measurement used in this document is "U" (1U = 1.75 inches or 44.45 mm). The total sum of the heights of all components in the rack measured in "U" cannot exceed the height of the rack. 1.1 Standard Components The standard rack consists of the following: • Removable vented front and rear doors • Removable side panels • Stabilizing feet • Leveling feet • Casters • Cable management brackets • M6 washer-face screws • M6 cage nuts

• Fixed monitor shelf • One 19-inch keyboard/touchpad with sliding shelf • 4-port keyboard/mouse/monitor switch box • Blanking panel kit (one 1U, one 2U, and one 3U) • Acer Altos storage subsystem 1.3 Screw Types Used The following screws are used in the assembly of the Acer Altos RM900 and other rack-mountable components: Screw Type Figure Usage M4 metal screw Securing the component rail to the mounting rail.

The four vertical rails of the Acer Altos RM900 contain square mounting holes arranged in a manner shown in this figure: Figure 4 Vertical Square Mounting Hole Spacing The distance from the center of two holes with closer spacing to the center of the next pair is equivalent to 1U. When installing components, you must start your measurement from the center of the two holes with closer spacing. Otherwise, the screw holes on the component may not match with those on the rack. 1U 1U 2U 0.25” 0.625” 0.625 0.5” 0.625” 0.625” 0.5”

The rack comes with casters to help you move it easily from one place to another. To position the rack: 1. Allow the following minimum clearances: For operation: Leave at least 46 cm (1.5 ft) of clearance in front of the rack and 31 cm (1 ft) behind the rack to allow adequate airflow. For servicing: Allow 61 cm (2 ft) of space behind the rack and 165 cm (65 inches) in front of the rack. 2. After you have positioned the rack, locate the two stabilizing feet and the two leveling feet placed just next to each caster. These feet are used for support to ensure that the rack is stable and to compensate for uneven floors when leveling the rack. See step 2 of Figure 5. 3. Pull out the two stabilizing feet. See step 3 of Figure 5. 4. Rotate each foot to adjust it. Continue adjusting the feet until the rack is level. See step 4 of Figure 5. Make sure the rack is stable.

The rack has one front door and one rear door. Both doors are vented and can be opened easily. To open the rack's front or rear door: 1. Slide the keylock cover as far as it will go, press the keylock button to automatically release the handle. If the door is locked, unlock it using the key. 2. Rotate the handle 90 degrees counter-clockwise until the latch releases, and then pull open the door. Step 1 Step 2 Figure 6 Opening the Rack Door To close the rack's front or rear door: 1. Shut the door and rotate the handle clockwise to its original position. 2. Push the handle until it clicks.

You may need to remove the front and rear doors when installing components into the rack or when servicing. To remove the front or rear door: 1. Open the door. See section 4. 2. Locate the release lever in the upper-right corner of the front door or in the upper-left corner of the rear door. 3. Using your finger, pull down the release lever. This releases the upper door holder. 4. When the upper holder is released, slightly lift the door to remove the lower holder from its slot. Figure 7 Removing the Rack Door To reinstall the front or rear door: 1. Place the lower holder into its slot. 2. Using your finger, pull down the release lever while fitting the upper holder into its slot. Step 3 Step 4 Release lever

Panels The rack comes with 4 side panels. When installing components or when servicing, you may need to remove all side panels for quick and easy access to the components. To remove the side panels: 1. Each side panel has two screws. Using a coin or any flat-head tool, rotate each screw 90 degrees clockwise (for the right panels) or counter-clockwise (for the left panels) to release the side panel. See A of Figure 8. 2. Use one hand to push the side panel (see B1 of Figure 8) and another hand to support it at the bottom (see B2 of Figure 8). 3. When the side panel is released, pull it out to totally detach it from the rack. Repeat the steps until all side panels are removed. See C of Figure 8. Figure 8 Removing the Side Panel A B1 B2 C

1. Locate the side of the panel that does not contain the screws. 2. Align the groove on that side of the panel with the edge of the rack, then insert it. See A of Figure 9. 3. Push the other side until it is completely inserted. See B of Figure 9. 4. Using a coin or any flat-head tool, rotate the two screws on the panel 90 degrees counter-clockwise (for the right panels) or clockwise (for the left panels) to secure the panel to the rack. See C of Figure 9. Figure 9 Replacing the Side Panel A B C

7.3.1 Installing the Mounting Rails The rails allow the system to slide in and out of the rackmount for maintenance purposes. Follow these steps to install the mounting rails: 1. Extend the component rails from the mounting rails until the component rail release latches click. Then hold down the latches and slip the component rails out of the mounting rails. See Figure 13. Figure 13 Removing the Component Rail from the Mounting Rail (for Acer Altos 1100 Server) 2. Put the component rails to one side. 3. Attach the mounting rails to the mounting brackets: i. Notice that each mounting rail consists of: • a fixed outer piece that screws into the mounting bracket • an inner sliding piece controlled by a steel ball gearing movement. This inner sliding piece is not detachable. latch component rail mounting rail

Fasten the mounting rail to the mounting bracket with three M5 screws. See Figure 14. Figure 14 Aligning and Fastening the Mounting Rail to the Mounting Bracket (for Acer Altos 1100 Server) vi. Adjust the inner sliding piece to align the two holes on the other end of the mounting bracket with the mounting rail. To adjust the inner sliding piece, press the latch located at the end of it and then push back the inner sliding piece. You can only align one hole at a time. Continue moving the inner sliding piece until you align one of the holes. See Figure 15. Be careful when pressing the latch. Use a screwdriver or any similar tool. step iii steps iv and v mounting rail mounting bracket

The cable carrier allows you to tie-wrap all cables to and from the server. As you slide the server in and out of the rack, the cable carrier collapses and extends, keeping the cables untangled and attached to the server. To attach the cable carrier: i. Attach one end of the cable carrier to the drawer using two M5 screws. See step i of Figure 27. ii. Install two cage nuts on the inside of the rack and then attach the other end of the cable carrier on the outside of the rear brace opposite the cage nuts with two M5 screws. See step ii of Figure 27. See section 7.1 for the installation of the cage nuts.

The cable management brackets helps you organize the wires and cables dangling inside the rack. To install a cable management backet: 1. Install a cage nut on the outside of the rail. 2. Attach the support bracket to the cable management bracket and then align it with the cage nut. Secure it with an M5 screw. To arrange the cabling inside the rack: 1. Connect any remaining cables such as network cables, SCSI cables, etc. 2. Route all cables to the cable management bracket located on the left column of the rack. The cable management brackets are designed to hold bundles of cables. Figure 57 Cable Management Brackets Location Cable management brackets

The rack may come with a blanking kit that includes three blanking panels: one 1U, one 2U, and one 3U. You may need to install these blanking panels to fill the empty spaces at the front of the rack. To attach a blanking panel: 1. Place the blanking panel across the front vertical rails of the rack and indicate the positions of the cage nuts. 2. Install four cage nuts on the inside of the rail (see section 7.1) and then align the blanking panel to the cage nuts. Secure the blanking panel with four M5 washer-face screws. Figure 58 Attaching Blanking Panels

Installation After you have installed all the necessary components into the rack and arranged the cabling, you need to replace the side panels, the rear door, and the front door to complete the installation.
