1. NAS Rails Installation 1.1. The following steps should be followed to properly mount the Aberdeen into a server rack. It is also recommended to reference the manufacturer s installation instructions that accompanied the rack. Confirm that all the rail hardware shown below has been included in the server package. - 2 Outer Fixed Rails for attachment to rack cabinet - 2 Inner Rails for attachment to the server chassis. - 2 Long & 2 Short brackets for attaching outer fixed rails to rack cabinets of varying depths. - 8 (Three-Hole) universal mounting adapter plates used in racks where existing screw holes vary in thread density. - 21 (Large) M6 screws used to secure the server chassis to the front of the rack. - 21 (Long) M5 screws and nuts used to attach the long & short brackets to the outer fixed rails. - 12 (Short) M4 screws used to attach the inner rails to the server chassis. Figure 1.1 Rails Kit Package Contents
Figure 1.2 Separating Rail Assembly Locate the two rack rail assemblies. These assemblies consist of two sections, an outer fixed section that secures to the rack cabinet and an inner section that secures directly to the server. Remove the fixed chassis rails by pulling and removing from the rail assemblies. It will be necessary to depress the locking tab as shown above to remove the inner rail completely from the rail assembly. Figure 1.3 Aligning Rails with Locking Chassis Tab Securely attach each inner rail to the left and right side of the chassis making sure to align and lock the front rail notch with the tab on the side of the chassis. Fasten inner rail to the side of the chassis using four M4 (Short) screws as shown above. Figure 1.4 Properly Installed Inner Chassis Rail
1.2. Determine where you would like to place the server in the rack then perform the following steps: Position the outer fixed rails at the desired location in the rack, keeping the sliding rail guide facing the inside of the rack. The outer rails must be attached on the inside part of the rack as shown below: Figure 1.5 Outer Fixed Rail Attachment (Front) Fasten the outer fixed rail to the inside front rail of the rack cabinet using the supplied M6 screws. It may be necessary to use the supplied 3-Hole adapter plates if the threaded holes of the rack cabinet are too big. (Note: Some racks such as APC Netshelter & HP use square holes for mounting servers. Special M6 Caged Nuts (Shown Below) must be used to properly mount the server. This mounting hardware is sometimes included with the rack cabinet and/or can be ordered directly from the manufacturer or obtained through a local distributor) Now that the front of the outer fixed rail has been attached to the inside front rail of the rack cabinet, the other end of the rail must be fastened to the inside rear rail of the rack.
Figure 1.5 Outer Fixed Rail Attachment (Rear) Level the outer fixed rail to the rear of the rack cabinet and fasten to the inside part of the rear rack rail using the supplied long or short brackets and M5 screws and locking nuts. Use of either the long or short mounting bracket is determined depending on the depth of the rack cabinet. Again, it may be necessary to use the supplied 3-Hole adapter plates if the threaded holes of the rack cabinet are too big for the supplied M6 screws. Repeat the above procedure on the other side of the rack to complete the outer rail installation. Figure 1.6 Completed Outer Rail Installation The rack rails should now be attached to both the chassis and the rack cabinet. The next step is to install the server into the rack cabinet.
1.3. Inserting the server into the cabinet Line up the rear of the chassis rails with the front of the rack rails. Slide the chassis rails into the rack rails, keeping even pressure on both sides, until they slide all the way back. (Note: This step should be completed with help from another person to avoid damage to the server, rack, or even personal injury. Remove the hot-swappable hard drives if necessary to lighten the load during installation into the rack cabinet.) If the server does not push back all the way, it may be necessary to depress the locking rail tabs while pushing the server back. These tabs prevent the server from falling out of the rack if maintenance is required. When the server has been pushed completely into the rack, conclude the installation by inserting and tightening the M6 screws that hold the front of the server to the rack.

Appendix A Long Version Sliding Rail Installation Guide This guide is for servers that require installation in extra deep cabinets. These rails are generally requested at the time of purchase instead of the standard rails. Accessories list Inner Rails Outer Rails 6 Extension 4 Extension Screws (L to R) M5 (24 pcs) for mounting Outer Rail to posts M4x8 (20 pcs) for mounting Inner Rail to Chassis Nut-plate (Top to Bottom) M4 nut-plate (4 pcs) M5 nut-plate (4 pcs) M4x6 (12 pcs) for extension bracket use Star Nut (12 pcs) for mounting extension brackets 1
A Mount External Rail to Rack Posts (A.1) Front Mounting Using Nut Plate Fasten the Outer Rail with M5 screw onto the Front Rack Posts if post has non-threaded holes such as square hole. Position nut-plate BEHIND the post and fit screws through the hole on the post from the front. Do not fasten the screw all the way, so there is gap to slide in the slotted flange on the outer rail into position. Tighten the screws after flange is fully seated. Adjust the lateral position of outer rail to meet inner rail position as needed. If cabinet post has threaded M5 holes, please use M4 screws fitted through M5 holes and fasten with M4 nut-plates. (A.2) Rear Mounting Fasten the Extension Bracket to the rear Outer Rail using 4 pcs M4x6 screws + Star Nuts. Adjust the post position, so outer rail will not take up any space between the left and right posts. Extension brackets can also be mounted to reach forward for shorter cabinets. Mount the Extension brackets slotted flange the same way as the outer rail front flange. This is how the Outer Rail looks on the Rack Post. 2
B Assemble Inner Rail to Chassis Fasten the Inner Rail to chassis using the M4x8 screws, and make sure the notch on the front of inner rail fits under the tab on the side of the chassis. Install 4(four) pcs of M4x8 screws on side of chassis to secure the inner rail. C Insert the Chassis into Cabinet Make sure the Inner & Outer Rail match & align properly, before pushing the chassis in. Push the release button on Inner Rail when it hits the outer rail, and again when it snaps into Outer Rail cut out, and then continue to push the chassis in (as shown in the pictures on the LEFT) The two pictures on the LEFT show how the Inner Rail snaps into the Outer Rail and the location of the release button. 3
D Installation Complete This is the how it looks like when the installation is complete. Note: This solid-bearing slide rail is supplied to provide easier mounting and dismounting of the system, and user is not encouraged to perform maintenance on a fully loaded system at full-extension position. Different racks might have different post design, but should have similar mounting. Sometimes rear posts need to be adjusted to fit the length of the rails. 4
