The slide rail assembly consists of a chassis rail and a slide rail. You need to separate the chassis rail from the slide rail so that you can install a mounting bracket to the slide rail and attach the chassis rail to the module chassis (see “Preparing the Module”). To separate the chassis rail from the slide rail, follow these steps:
Remove the two slide rail assemblies and the rear mounting brackets from the shipping container.
Extend each slide rail assembly until the safety latch snaps into place.
Press the safety latch and remove the chassis rail from the slide rail, as shown in Figure B-1.
Place one of the mounting brackets on the back of the slide rail, as shown in Figure B-2. Adjust the position of the mounting bracket on the slide rail according to the depth of the rack.
Place a bar nut behind the mounting bracket. Secure the mounting bracket to the slide rail by inserting two 10-32 x 1/2-in. screws through the slide rail mounting bracket into the bar nut, as shown in Figure B-2.
Repeat steps 4 and 5 to attach a mounting bracket to the other slide rail.
To attach the chassis rails to the module, follow these steps:
Place the module on a flat, stable surface.
Using five 10-24 x 1/4-in. screws, attach one of the chassis rails to the right side of the module chassis. Ensure that the rail is installed in the correct direction (see Figure B-3).
Caution: Use only the 1/4-in. (0.64 cm) length screws. Longer screws damage internal components of the chassis. Repeat Step 2 to mount the second rail to the left side of the module chassis.
The module requires two units (U) of space within the rack. (One unit is equivalent to 1.75 in. [44.5 cm].) To determine where you should install the slide rails in the rack, you must count mounting holes. Each U contains three mounting holes; therefore, in the 2U of space that the module occupies, there are six mounting holes. The bottom hole of the 2U space is hole 1. The top mounting hole in the 2U space is hole 6. See Figure B-4.
 | Note: Modules in the rack are identified by the lowest U number they occupy. For example, in Figure B-4 the module resides in U5 (the fifth unit within the rack). |
To determine how many mounting holes you must count, use the following formula: 3 x (the lowest U number that the module will occupy) - 2. For example, when you want to install the module in locations U9 and U10, count 25 mounting holes (3 x 9 - 2) starting from the bottom of the rack. The 25th hole is the first mounting hole of U9.
To attach the slide rail to the rack, follow these steps:
 | Tip: The slide rails must be level in the rack. To ensure that you install the slide rails correctly, carefully count the mounting holes on all of the rack rails (two front rails and two rear rails). |
Locate eight 10-32 x 1/2-in. Phillips screws, eight shoulder washers, and four bar nuts.
Place one of the bar nuts inside the rack and align it with the second and third holes of the selected 2U of space (see Figure B-5).
Note: The holes in the bar nuts are not centered. The bar nuts need to be oriented so that the holes are closest to the inside edge of the rack rails. See Figure B-5. Insert two screws with shoulder washers through the rack rail to hold the bar nut in place. Do not be tighten the screws at this time.
Repeat Steps 2 and 3 to install the remaining three bar nuts on the other three rack rails (front and rear of rack).
Insert the front and rear brackets of one of the slide rails between the rack rails and the bar nuts, as shown in Figure B-6.
Tighten the screws on the front- and rear-ends of the rails. Do not tighten firmly at this time, because all screws will be firmly tightened once the module is installed in the rack.
Repeat steps 5 and 6 to attach the second slide rail to the other side of the rack.
Clip nuts secure the modules to the rack. To install the clip nuts, slide the clip nuts over the fifth hole of the selected 2U of space on each of the front rails. See Figure B-7 for details.
To install a module in the rack, follow these steps:
| Note: Step 2 requires two people. |
Fully extend the left and right slide rails from the rack until they lock into place.
With one person holding each side of the module, align the chassis rails of the module with the slide rails of the rack.
Slide the chassis rails into the slide rails until the chassis rails are stopped by the safety latches.
Press the safety latches on both sides of the module to fully seat the chassis rails into the slide rails (see Figure B-8).
Firmly tighten all screws (the eight screws that secure the slide rails to the rack rails).
Secure the module to the rack by inserting a 10-32 x 1/2-in. Phillips screw in the top hole of each chassis ear (see Figure B-9).
Once the module is installed in the rack, you can make minor adjustments to its position in the rack (upward and side-to-side). To adjust the position of the module, loosen the front mounting screws, adjust the module to the desired position, and then tighten the mounting screws.
| Caution: Do not lift the module by its bezel; it is not designed to handle the weight of the module. Instead, use the chassis ears to move the module (see Figure B-10). |
To remove a module from the rack, follow these steps:
Power off the module. For instructions on how to power off the module, see “Powering Off the Workstation” in Chapter 1.
Disconnect all of the cables at the rear of the module.
Warning: Components may be hot. To avoid injury, allow the components to cool for approximately five minutes before you proceed with these instructions. Remove the two screws that secure the system to the front rails of the rack.
Carefully pull the module out of the rack until it is stopped by the safety latches.
With one person holding each side, release the safety latches on both sides of the module and pull it out of the slide rails (see Figure B-10).
Place the module on a flat, stable surface.
To slide the slide rails back into the rack, push down on the slide latches as shown in Figure B-11.
Note: Before you can reinstall a module into the rack, you must fully extend the slide rails from the rack until they lock into place.
