You previously installed the GND lug and bracket assembly, with ground wire attached, to the S4048T-ON chassis, see Ground lug and bracket installation.
You must supply: • One two-hole UL-certified GND lug to attach the ground wire to the rack • Two National Electric Code (NEC)-compliant screws to attach the GND lug to the rack • Anti-oxidant compound • Crimping tool 1 Measure and cut a length of wire sufficient to reach between the system-installed GND lug and the rack-end GND lug. 2 Attach the end of the wire to the rack-end GND lug. a b c Coat the bare end of the wire with an anti-oxidant compound. Insert the end of the wire into the lug.
AC or DC power supply installation The S4048T-ON supports two hot-swappable power supplies with integrated fans that provide cooling for the chassis. The system supports AC power supplies with two air-flow directions—I/O to Utility and Utility to I/O. 1 Remove the PSU from the electrostatic bag. 2 Remove the PSU slot cover from the switch. 3 Use the grab handle to slide the PSU into the switch PSU slot. The PSU slot is keyed such that the PSU can only be fully inserted in one orientation.
WARNING: ESD damage can occur if components are mishandled. Always wear an ESD-preventive wrist or heel ground strap when handling the system and its components. WARNING: To prevent electrical shock, ensure that the system is grounded properly. If you ground your equipment incorrectly, excessive emissions may result. To ensure that the power cables meet your local electrical requirements, use a qualified electrician. CAUTION: DO NOT mix airflow directions.
5 DC power source wires—black, green, blue 1 Strip 1/2 inches of insulation from each of the site’s DC power source wires, item 5. 2 Insert each of the site’s DC power source’s bare wire lengths into the wiring block, matching wire colors, items 3 and 4. WARNING: Do not cross the wires—In the wiring block, blue aligns with blue, green aligns with green, and black aligns with black. 3 Use a flat-blade screwdriver to tighten the screws that secure the bare wires into the wiring block.
Figure 13. Install the Fan Module CAUTION: DO NOT mix airflow directions. All fans must use the same airflow direction (I/O to PSU side or PSU to I/O side). CAUTION: Check the fans at six-month intervals and replace them as necessary. To accurately determine replacement intervals, regularly monitor the speeds of the cooling fans. Installing the SFP+ and QSFP+ Optics The S4048T-ON system has 48 RJ-45 ports and six quad small form-factor pluggable plus (QSFP+) optical ports.
NOTE: Both rows of QSFP+ ports require that you install the 40 GbE optics with the tabs facing up. NOTE: When you cable the ports, be sure not to interfere with the airflow from the small vent holes above and below the ports. Supply Power and Power Up the System Dell Networking recommends reinspecting your system prior to powering up. Connecting the power cable powers up the switch. Verify that: • The equipment is properly secured to the rack. • The equipment rack is properly mounted and grounded.
