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, two-post, or threaded methods). The Dell ReadyRails™ system is provided for one 1U front-rack, and two-post installations. The ReadyRails system includes two separately packaged rail assemblies and two rails that are shipped attached to the sides of the switch.
Installing the Dell ReadyRails System The ReadyRails rack mounting system is provided to easily configure your rack for installation of your S4820T switch. The ReadyRails system can be installed using the 1U tool-less method or one of three possible 1U tooled methods (two-post flush mount, two-post center mount, or four-post threaded).
Two-post Flush-mount Configuration For this configuration, you must remove the castings from the front side of each ReadyRails assembly. Refer to Figure 4-2, step 1. 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 Slide the plunger bracket rearward until it clicks into place and secure the bracket to the front post flange with two user-supplied screws. Refer to Figure 4-3, step 1. Figure 4-3. Two-post Center-mount Configuration Slide the back bracket towards the post and secure it to the post flange with two user-supplied screws.
Four-post Threaded Configuration For this configuration, you must remove the flange ear castings from each end of the ReadyRails assemblies. Use a Torx driver to remove the two screws from each flange ear and remove each casting. Refer to Figure 4-4, step 1.
Use a single M4x0.7 screw to attach the ground cable to the chassis. The cable itself is not included with the S4820T. To properly ground the chassis, Dell Force10 recommends using a 6AWG one-hole lug, #10 hole size, 63" spacing (not included in shipping). The one-hole lug must be a UL recognized, crimp-type lug.
PSU to I/O). Two PSUs are required for full redundancy, but the system will operate with a single PSU. NOTE: If you use a single PSU, you must install a blank plate in the other PSU slot. Dell Force10 recommends using power supply 1 (PSU1) as the blank plate slot.
