Installation Requirements
System installation requires the following:
• A cabinet with an internal rail dimension range of 24.25 inches to 25.0 inches.
• A vertical cabinet mounting space of 10.5 inches for the shelf assembly.
• The chassis slides must be installed at the first hole above a one-half inch RETMA space.
Some cabinets or configurations may require cable retraction or cable management devices other than the one
included in this kit.
Required Installation Tools
To install your rackmount kit, you need the following tools:
• Wrench to tighten the ball studs
• Socket wrench to install the front bezel to the tray
• Phillips-head screwdriver
• Flat-head screwdriver

Assembling the Slides
Figure 1 shows the chassis slides, which support the shelf. The slides require some assembly before mounting
them in the cabinet. The callouts in the figure refer to the parts listed in Table 1.

7 Slide bracket, rear left-hand (LH) 21 Chassis slide, ball bearing
16 Pan head screw
To assemble the slides, perform the following steps:
1. The short slide with the chamfered edge on the upper side goes in the front of the cabinet and the long slide
with the chamfered edge on the upper side goes in the rear.
2. Attach the front slide bracket , RH (4) and the rear slide bracket, RH (6) by using the pan head screws (16),
flat washers (17), lock washers (18), and hex nuts (19).
3. Repeat step 2 for the front slide bracket, LH (5) and the rear slide bracket, LH (7).

Installing the Slides into the Cabinet
To install the slides into the cabinet, perform the following steps:
1. Before installing the slides into the cabinet, select the cabinet location for your server system. The server
needs 10.5 inches of rack space. Mark the bottom of the 10.5-inch space with a pencil mark.
2. Locate the first hole above the 1/2 inch RETMA space (hole 1), and count up to holes 2 and 3 on the front and
on the rear of the cabinet.
3. Skip hole 1 and place the slides behind the cabinet rail in holes 2 and 3, front and rear.
4. Place the eight screws (34) and washers (35) in the holes and fasten to the four nut bars (10), and tighten.
5. Place the two kep nuts, #10-32, (14) over hole 5 on the front cabinet rails. Add the two ball studs (13) and
tighten with a wrench.

5
Assembling the Front Bezel
To assemble the front bezel, perform the following steps:
1. Install the concealed pull (11), to the front bezel (1) by using the two plastic screws and caps (supplied with
the pull).
2. Fasten the bezel to the system shelf (2) by using keps nuts (22) and tighten with a socket wrench.
3. Extend the slides all the way out of the cabinet. Use the six sems screws with external tooth lock washers
(36) and tighten three screws on each side of the shelf. The screws go through the slides and into the shelf.
Installing the Server Unit
To install the server unit into the cabinet, refer to Figure 3 and perform the following steps:

Caution
The server unit weighs 70 pounds. Please use the proper number of personnel to move the unit.
1. Pull the shelf out of the cabinet.
2. Put the server unit in the cabinet shelf.
3. Slide the server unit forward. Install the locking bracket (3) in the middle rear of the shelf with two 8-32
screws (16) and two flat washers (17). Two metric screws (12) go through the bracket and into the back of the
server assembly.
4. Ten cable clamps (20) are available for 10 additional holes that house cables. Place the hole of the cable
clamp over the assembly hole and secure with the screw and washer (16 and 17).

6
Installing the Interlock Actuator Latches
If additional products are installed into the cabinet, actuator latches for those products should be installed. To
install actuator latches, refer to Figure 4 and proceed as follows:
Note
Part numbers (40), (41), and (42) are not part of this kit, rather they are part of the H9A10 cabinet.
1. Remove the screws securing the bottom mounting bracket to the cabinet (41).
2. Slide the mounting bracket off the bottom of the vertical bar (40).
3. Slide the stabilizer bracket (29) for the new product onto the bottom of the vertical bar.
4. Slide the actuator latch (30) for the new product onto the bottom of the vertical bar.
5. Replace the bottom mounting bracket (41) and install the screws removed in step 1 but do not tighten them.
6. Position the stabilizer bracket so that the bottom hole in the stabilizer bracket (42) aligns with the RETMA
rail hole adjacent to the bottom of the installed product. This may require the loosening and sliding of other
latches and stabilizer brackets to accommodate the new configuration.
7. Place the nut plate (31) behind the RETMA rail and install and tighten the two 10-32 truss-head screws (33)
provided to secure the stabilizer bracket.
8. Position the new actuator latch (30) to properly engage the interlock actuator (9), and tighten the two 6-32 set
screws (32) to secure the latch.
9. Now tighten the screws to secure the bottom mounting bracket (41).
The expanded view (A) shows the position of the actuator latches when all systems are pushed into the cabinet.
The expanded view (B) shows the position of all actuator latches after one system has been pulled out.
Note
The interlock system is compatible with the AlphaServer 1000, AlphaServer 1000A, and AlphaStation 600 RM
series systems. Other systems may not be compatible because the interlock actuator may not engage properly. In
these cases, do not install the interlock actuator on those systems.
WARNING
If a system is installed without an interlock actuator or the vertical bar in the cabinet does not engage
properly with the interlock actuator, it is the customer's responsibility to provide a stable cabinet.

Installing a Shipping Bracket
To lock the shelf into place for shipping or moving, perform these steps:
1. Face the rear of the cabinet and place the wide end of the shipping bracket (8) to the left over two holes on
the left side of the shelf.
2. Tighten two truss head screws (15) on the side holes and tighten another truss head screw (15) to hold the
shelf to the back of the rail.
