6 N30xx Series Installation You can mount the N30xx Series switches in a standard 48.26 cm (19-inch) rack or placed on a flat surface. Make sure that the chosen installation location meets the following site requirements: • Power — The switch is installed near an easily accessible 100–240 VAC, 50–60 Hz outlet. • Clearance — There is adequate front and rear clearance for operator access. Allow clearance for cabling, power connections, and ventilation.
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 twopost installations. The ReadyRail system includes two separately packaged rail assemblies. WARNING: This is a condensed reference.
Figure 17. 1U Tool-less Configuration 2-Post Flush-Mount Configuration To install the Dell ReadyRails system using the two-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 18. 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.
2-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 19. 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 19.
Figure 20. 4-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 21. 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.
