mm). The total sum of the heights of all
components in the rack measured in "U"
cannot exceed the height of the rack.

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

2.4 Vertical Mounting Hole Pattern

The four vertical rails of the Acer Altos RM900 contain square
mounting holes arranged in a manner shown in this figure:

0.25”

1U

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.

3 Positioning the Rack

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.

4 Opening and Closing the Door

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

5 Removing and Reinstalling the Door

Step 4

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.

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.

9 Attaching the Blanking Panels

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.
