NEBS-compliant ground installation

Important information
WARNING: The quad form-factor pluggable (QSFP), console, Ethernet management, and universal serial bus (USB) ports are
suitable for connection to intra-building or unexposed wiring or cabling only. You MUST NOT metallically connect the ports to
interfaces that connect to the out side plant (OSP) or its wiring. Use these interfaces as intra-building interfaces only (Type 2 or
Type 4 ports as described in GR-1089-CORE, Issue 6) and they require isolation from the exposed OSP cabling. Adding primary
protectors is not sufficient protection to connect these interfaces metallically to OSP wiring.
WARNING: If you install and connect the S6100-ON to a commercial AC power source, you must connect the system to an
external special protection device (SPD).
To be NEBS-compliant, you must follow these regulations:
• Locate your system in a restricted-access area were only trained personnel are allowed access.
• Install and connect your system to the common bonding network (CBN).
• You can also install and connect your system to the central office.
• Connect the battery returns of your system as DC-I.
• Ground your system using a copper ground conductor.
• Clean all bare grounding connection points on your chassis and the bracket with an anti-oxidant solution before making connections.
• Use the two-hole, Listed, compression-type lug with a AWG 14 gauge wire to secure your system to the frame.
NOTE: The S6100–ON can operate at -48 to -60 VDC at a maximum current level of 24A.
NOTE: The S6100-ON is Earthquake Z4-compliant when you attach the ReadyRails to the four-post frame using threaded
hardware.
NEBS-compliant ground installation
Before you install the switch into a rack, install the ground (GND) lug assembly.
The accessory box includes a UL-certified GND lug and two nuts, packaged separately. If any parts are missing, contact your Dell Sales
Representative.
CAUTION: Grounding conductors must be made of copper. Do not use aluminum conductors.
NOTE: The rack installation ears are not suitable for grounding.
NOTE: Coat the two-hole lug with an anti-oxidant compound before crimping. Also, bring any unplated mating surfaces to a shiny
finish and coat with an anti-oxidant before mating. Plated mating surfaces must be clean and free from contamination.
