Installing Rack or Cabinet Hardware You may either place the switch on the rack shelf or mount the switch directly into a 19" wide, EIA-310E- 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. WARNING: This is a condensed reference.
www.dell.com | support.dell.com 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). 1 With the ReadyRails flange ears facing outward, place one rail between the left and right vertical posts.
Two-post Flush-mount Configuration 1 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. It is not necessary to remove the rear flange castings. Figure 4-2.
www.dell.com | support.dell.com Two-post Center-mount Configuration 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. 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. Refer to Figure 4-3, step 2. 3 Repeat this procedure for the second rail.
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. Retain the castings for future rack requirements. 2 For each rail, attach the front and rear flanges to the post flanges with two user-supplied screws at each end. Refer to Figure 4-4, step 2. 1 Figure 4-4.
www.dell.com | support.dell.com Installing the S4820T Switch You can mount the switch in the 1U front-rack or 1U two-post (flush and center) configurations. The following is an example of a front-rack configuration. For the 1U two-post (flush and center) configurations, you can slide the switch into the rails in the same manner as the four-post configurations. 1U Front-rack Installation You must configure the rails that are attached to the switch.
NOTE: Coat the one-hole lug with an anti-oxidant compound prior to crimping. Also, bring any un-plated mating surfaces to a shiny finish and coat with an anti-oxidant prior to mating. Plated mating surfaces must be clean and free from contamination. Take the one M4x0.7 screw from the package. 2 Cut the cable to the desired length. The cable length must facilitate proper operation of the fault interrupt circuits. Dell Force10 recommends using of the shortest cable route allowable.

5 Power Supplies The S4820T supports two hot-swappable power supplies units (PSUs) with integrated fans that provide cooling for the system. The S4820T supports AC power supplies with two air-flow directions (normal and reversed). 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.
www.dell.com | support.dell.com The PSUs are in a single piece with the PSU fans (see Figure 5-1). You can replace the fan trays individually, but you cannot replace the fans that are attached to the PSUs—if the fans attached to the PSU fail, you must replace the entire PSU. For fan tray replacement procedures, refer to Chapter 6, Fans. WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this system with the safety cover removed.
To replace an AC or DC power supply, follow these steps: Step Task 1 Disconnect the power cable from the PSU. 2 Loosen the securing screws on the PSU with a screwdriver. Ensure that the PSU loose and can be easily removed. 3 Use the grab handle to slide the PSU out of the power supply bay. 4 Use the grab handle on the replacement PSU to slide the PSU into the power supply bay. 5 Tighten the securing screws on the replacement PSU with a screwdriver. Ensure that the PSU is secure.
www.dell.com | support.dell.com To connect a S4820T DC PSU to the site’s DC power source, follow these steps: Step Task 1 Strip 1/2” of insulation from each of the power connector’s wires (red and black, See Figure 5-2). 2 Insert each of the power connector’s bare wire lengths into the wiring block (See Figure 5-2). Red into one hole and black into the other hole. 3 4 Use a flat-blade screwdriver to tighten the screws, which secures the bare wires into the wiring block.
6 Fans The S4820T comes from the factory with one power supply unit (PSU) and two fan modules installed in the chassis (see Figure 6-1). The fan modules and the integrated fan-power supply are hot-swappable. NOTE: To run the system, both slots must have operating fan units. If a module is not installed in each slot (either as part of the PSU or as an independent fan module), the system shuts down in one minute.
www.dell.com | support.dell.com Install a Fan Module CAUTION: DO NOT mix airflow directions. Both fans must use the same airflow direction (reverse or normal). If the airflows are mismatched, an error message appears and the system shuts down. 00:02:19:%S4820T:0%CHMGR-2-PSU_TYPE_AIRFLOW_MISMATCH: Mismatching PSU airflow detected. Unit 0 shall get shutdown in next 60 seconds if mismatch not rectified.
7 Management Ports Besides the 10 Gigabit and 40 Gigabit switch ports, the S4820T provides several ports for management and storage. Accessing the RJ-45 Console Port (RS-232) NOTE: Before starting this procedure, be sure that your PC has a 9-pin serial port and that you have a terminal emulation program already installed and running on the PC. NOTE: If your PC’s serial port cannot accept a female DB-9 connector, you need to acquire a DB-9 male-tomale adaptor.
