S4048-ON installation You can mount the switch in the 1U front-rack or 1U flush and center two-post configurations. The following is an example of a front-rack configuration: For the 1U flush and center two-post configurations, slide the switch into the rails in the same manner as the four-post configurations.
Figure 10. Switch rails attachment 2 After you have installed both switch rails, line them up on the previously mounted Ready-Rails and slide the switch in until it is flush with front of rack. About 3 inches before you fully insert your switch, 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 Ready-Rails as a shelf or a workplace.
Figure 11. S4048-ON front-rack configuration Ground cable Dell EMC recommends grounding your switch. To attach the ground cable to the chassis, use a single M4x0.7 screw. The cable itself is not included with the S4048–ON. To properly ground the chassis, Dell EMC recommends using a 6 AWG one-hole lug, #10 hole size, 63" spacing, not included in shipping. The one-hole lug must be a UL recognized, crimp-type lug. CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.
CAUTION: ESD damage can occur if the components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the S4048–ON and its components. WARNING: When working with optical fibers, follow all the warning labels and always wear eye protection. Never look directly into the end of a terminated or unterminated fiber or connector as it may cause eye damage. 1 Position the optic so it is in the correct position. The optic has a key that prevents it from being inserted incorrectly.
6 Power supplies The S4048–ON ships with one AC power supply. Dell EMC recommends purchasing a second power supply. The S4048–ON supports AC power supplies with two air-flow directions, normal and reverse. Normal is from the I/O-side to the PSU-side. Reverse is from the PSU-side to the I/O-side. Two PSUs are required for full redundancy, but the switch can operate with a single PSU. The PSUs are field replaceable.
The PSUs have an integrated fan, which you cannot replace individually; if the fans integrated in a PSU fails, you must replace the entire PSU. You can replace the fan trays individually. For fan tray replacement procedures, refer to Fans. WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this switch with the safety cover removed. CAUTION: Remove the power cable from the PSU prior to removing the PSU.
b Slot When you install the PSU correctly, it snaps into place and is flushed with the back of the switch. 4 Plug in the appropriate AC three prong power cord from the switch PSU to the external power source. 5 If you have a redundant PSU, a second PSU, repeat steps 1 through 4 above using the second PSU slot on the S4048-ON switch. NOTE: The S4048-ON powers up when the cables are connected between the power supply and the power source.
