QM9700/QM9790 Tool-Less Rail Kit

The following parts are included in the tool-less rail kit (see figure below):

• 2x System Rails (A)

• 2x Rack Rails (B)

Rail Kit Parts

A, B

Prerequisites:

Before mounting the system to the rack, select the way you wish to place the system. Pay attention to the airflow within the rack cooling, connector and cabling options.

While planning how to place the system, review the two installation options shown in the table below, and consider the following points:

• Make sure the system air flow is compatible with your installation selection. It is important to keep the airflow within the rack in the same direction.

• Note that the part of the system to which you choose to attach the rails (the front panel direction, as demonstrated in Option 1 or the FRUs direction, as demonstrated in Option 2) will determine the system’s adjustable side. The system’s part to which the brackets are attached will be adjacent to the cabinet.

• The FRUs, as well as high-speed and MNG cables, must be extracted for replacement as part of the switch service. Consider this when planning the switch installation.

1	Extract the system rail (Part A): Extract the system rail (Part A) from the rack rail (Part B). Press the spring latch, and pull the system rail out, as shown in the following illustration:
2	Mount the systems rails (Part A) onto the chassis: Attach the switch to the left and right system rails (Part A) Secure the assembly by pushing the chassis’ pins through the slider key holes, until a click is heard and locking occurs.
3	Install the rack rails (Part B) on the rack. Mount both of the rack rails (Part B) into the rack by angularly inserting the brakes located at the rails edges into the designated slots in the rack unit. Align both rack rails (Part B) to sit horizontally in parallel to the rack assembly. Pull the rack rails' telescopic extensions all the way to the rack's opposite side, and insert the latches at the rails' free edges to the rack's slots. A click should be heard as the spring latches are fully inserted and locking occurs.
4	Mount the chassis onto the rack. Note At least two people are required to safely mount the system in the rack. Slide the rails installed on the system into the channels in the rack rails. Tighten the captive screws on both sides to further secure the system to the rack's posts.
5	A cable retainer should be used to secure the power cord when plugging it into each power socket (located on the rear side of the switch). To secure the power cord inside the retainer, press the small tab on the retainer strip to loosen the loop and pull. (The following diagram is for general illustration; the rear view does not necessarily match that of the actual system).

To remove the system from the rack:

1. Turn off the system and disconnect it from peripherals and from the electrical outlet.

   While your installation partner is supporting the system’s weight:

2. Loosen the captive screws attaching the system's rails to the rack's posts.

3. Use two hands to pull the system out until the rails are stopped.

4. Press the spring latches on both sides of the rack, and continue to pull the system out until the rack rails are clear of the system's rails.

5. Remove the rails from the system. Release the metal latches and pull out the rails, so the system's pins will be removed out of the oval slots.

6. Remove the rails from the rack by pressing the lock button, and pull the rails outside of the rack assembly.
