5 Inspect the product and accessories for damage. Rack Mounting an N30xx Switch You may either place the switch on the rack shelf or mount the switch directly into a 19" wide, EIA-310-E compliant rack (four-post, twopost, or threaded methods). The Dell ReadyRail system is provided for 1U front-rack, and two post installations. The ReadyRail system includes two separately packaged rail assemblies. WARNING: This is a condensed reference.
Figure 14. 1U Tool-less Configuration 2-Post Flush-Mount Configuration To install the Dell ReadyRails system using the 2-post flush-mount configuration, follow these steps. 1 For this configuration, remove the castings from the front side of each ReadyRails assembly. See item 1 in Figure 15. Use a Torx driver to remove the two screws from each front flange ear (on the switch side of the rail) and remove each casting. Retain the castings for future rack requirements.
Two-Post Center-Mount Configuration To install the Dell ReadyRails system using the two-post center-mount configuration, follow these steps. 1 Slide the plunger bracket rearward until it clicks into place and secure the bracket to the front post flange with two user-supplied screws. See item 1 in Figure 16. 2 Slide the back bracket towards the post and secure it to the post flange with two user-supplied screws. See items 2 and 3. 3 Repeat this procedure for the second rail. Figure 16.
Figure 17. Four-Post Threaded Configuration Install the N30xx System You can mount the system in the 1U front-rack or 1U two-post (flush and center) configurations. The following is an example of a frontrack configuration. For the 1U two-post (flush and center) configurations, slide the system into the rails in the same manner as the four-post configurations. Installing a 1U Front-Rack You must configure the rails that are attached to the system.
Figure 18. Attaching the Switch Rails 2 1 Front standoff locking tab 3 Locking tab 2 Switch After you have installed both switch rails, line them up on the previously mounted ReadyRails and slide the switch in until it is flush with front of rack. About 3 inches before you fully insert your system, the rail locking feature engages to keep the switch from inadvertently sliding out of the rack and falling. NOTE: Do not the use the mounted ReadyRails as a shelf or a workplace. Figure 19.
Install the switch on a flat surface if you are not installing it in a rack. The surface must be able to support the weight of the switch and the switch cables. The switch is supplied with four self-adhesive rubber pads. 1 Attach the self-adhesive rubber pads on each location marked on the bottom of the switch. 2 Set the switch on a flat surface. Make sure that it has proper ventilation by leaving 5 cm (2 inches) on each side and 13 cm (5 inches) at the back.
