The following image shows the M4 screws, mounting rails, mounting rail guides, and mounting ears. The image depicts the components for the Cisco Nexus 5548UP switch. As such, the brackets are be slightly larger than the ones shown here in the image.
- Attach the ears to the sides of the switch with four M4 screws per bracket so that the face of the switch is mounted with a 2 inch setback as shown in the image below.
This way the switch extends 2 inches past the rear EIA rails. The switch shown in the image is a Cisco Nexus 5548UP, but the mounting of the bracket is almost identical.
- Install the rear mounting bracket to the rear of the switch with four M4 mounting screws as shown below.
The diagram shows a Cisco Nexus 5548UP switch, but the mounting is nearly identical.
- Attach the second set of slide rails to the front of the rack in positions U39 and U40 using M5 screws.
Important: Be sure to install the caged nuts on the front of the rack in the center positions of each rack unit that will be occupied by a switch prior to installing the switches. It's not possible to do so later.
