Install the MX301

Mount the MX301 on a four-post square-holed rack on your site by following the recommended procedure below.

1. Review the General Safety Guidelines and Warnings.
2. Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist. Connect the other end to a site ESD point.
3. Install the chassis bracket to the chassis by aligning the keyholes on the chassis bracket over the shoulder screws on the chassis. Slide the chassis bracket toward the rear of the chassis.

4. Assemble the mounting rails by sliding the rear-floating rails into the respective front-mounting rails.
   Figure 3: Assemble the Mounting Rails
5. Install the mounting rails on the four-post rack:
   1. Use the guide pin to align the guide blocks of the rear-floating rails with the corresponding rear post holes. Pull the rear-floating rails toward the front of the rack to lock the rail in place. You will hear a distinct click sound when each latch locks into the corresponding rack post holes.

   2. Align the guide blocks of the front-mounting rails with the front post holes. Push the front-mounting rails towards the rear of the rack to lock the rails in place. You will hear a distinct click sound when each latch locks into the corresponding rack post holes.

   3. Visually confirm that you have locked the front and rear latches of the mounting rails into the rack posts. The mounting rails should now be securely installed on the rack.
6. Lift the device and position it in the rack, aligning the chassis brackets with the mounting rails. Slide the device all the way into the channels of the rack mounting rails.

Mount the MX301 on a four-post threaded hole rack on your site by following the recommended procedure below.

1. Review the General Safety Guidelines and Warnings.
2. Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist. Connect the other end to a site ESD point.
3. Install the chassis bracket to the chassis by aligning the keyholes on the chassis bracket over the shoulder screws on the chassis. Slide the chassis bracket toward the rear of the chassis.

4. Assemble the mounting rails:
   1. Remove the guide blocks from the front-mounting rails by loosening the screws and washers.
      Tip:

      Retain the guide blocks, screws, and washers for later use.

   2. Remove the guide blocks from the rear-floating rails by loosening the screws and washers.
      Tip:

      Retain the guide blocks, screws, and washers for later use.

5. Install the mounting rails on the four-post rack:
   1. Align and insert the guide pins of the rear-floating rails into the corresponding rear-post holes. Pull the rear-floating rails toward the front of the rack to lock the rails in place. You will hear a distinct click sound when each latch locks into the corresponding rack hole.

   2. Align and insert the guide pins of the front-mounting rails into the corresponding front-post holes. Push each front-mounting rail into the corresponding front-post hole toward the rear of the rack to lock the rails in place. You will hear a distinct click sound when each latch locks into the corresponding rack hole.
   3. Secure the front-mounting rails to the front rack post by using screws (not provided) appropriate for the thread size of your rack.

7. Tighten the two thumbscrews (in a clockwise direction) to secure the device.
   Figure 18: Tighten the Thumbscrews

Mount the MX301 on a two-post rack on your site by following the recommended procedure below.

1. Review the General Safety Guidelines and Warnings.
2. Wrap and fasten one end of the electrostatic discharge (ESD) cable grounding strap around your bare wrist. Connect the other end to a site ESD point.
3. Install the chassis bracket to the chassis by aligning the keyholes on the chassis bracket with the three shoulder screws at the rear of the chassis. Slide the chassis brackets toward the rear of the chassis until the chassis brackets lock into place.
   Figure 19: Install the Chassis Brackets
4. Have one person grasp both sides of the device, lift it, and position it in the rack so that the chassis bracket is aligned with the rack post holes.
5. Have a second person secure the chassis to the rack. Tighten the Philips M5x12 mm screws into the holes of the two-post rack. Use cage nuts and washers if your rack requires them.

6. Inspect the installation making sure that the chassis is level. Verify that the two screws on one rack post is level with the corresponding screws on the other rack post.
