The ground cable is not included. To properly ground the switch, Dell Technologies recommends a one- or two-hole lug, M4 hole
size. The grounding lugs must be a UL-recognized, crimp-type lug.
CAUTION:
Grounding conductors
must
be made of copper. Do not use aluminum conductors.
NOTE:
Coat the one-hole lug with an antioxidant compound before crimping. Also, bring any unplated mating surfaces to a
shiny finish and coat with an antioxidant before mating. Plated mating surfaces must be clean and free from contamination.
NOTE:
The conductor screw cannot be smaller than the conductors supplying power. Secure all screws and ground-wire
connections.
NOTE:
The rack installation ears are not suitable for grounding.
1. Cut your ground cable (not included) to the wanted length. The cable length must facilitate proper operation of the fault
interrupt circuits. Use the shortest cable route allowable.
NOTE:
The ground cable must be 10 AWG minimum. The nominal thread diameter screw type is 4.0 mm (0.157 in).
2. Using one of the two M4 threaded holes, attach the ground cable to the lug. Use an M4 screw with a captive internal tooth
lock washer. Torque the screw to ±5 - 6 in-lbs.
3. Attach the other end of the ground cable to a suitable ground point such as the rack or cabinet.
The rack installation ears are not a suitable grounding point.
Rack or cabinet installation
You may either place the switch on a rack shelf or mount the switch directly into a 19" wide, EIA-310- E-compliant rack. These
installation procedures are for four-post rack installation only.
The rails system includes two separately packaged rail assemblies. To begin installation, separate each rail assembly by sliding
the inside rail out of the outside rail.
WARNING:
This guide is a condensed reference. Read the safety instructions in your
Safety, Environmental, and
Regulatory
information booklet before you begin.
NOTE:
The figures are not intended to represent a specific switch.
NOTE:
Do not the use the mounted rails as a shelf or a workplace.
Rack mount safety considerations
●
Rack loading—Overloading or uneven loading of racks may result in shelf or rack failure, possibly damaging the equipment
and causing personal injury. Stabilize racks in a permanent location before loading begins. Mount the components starting at
the bottom of the rack, and then work to the top. Do not exceed your rack-load rating.
●
Power considerations—Connect only to the power source specified on the unit. When you install multiple electrical
components in a rack, ensure that the total component power ratings do not exceed the circuit capabilities. Overloaded
power sources and extension cords present fire and shock hazards.
●
Elevated ambient temperature—If you install the switch in a closed rack, the operating temperature of the rack environment
may be greater than the room ambient temperature. Use care not to exceed the 45°C (113°F) maximum ambient
temperature of the switch.
●
Reduced air flow—Do not compromise the amount of airflow that is required for safe operation of the equipment. Install the
equipment in the rack so that the equipment constantly has the correct amount of airflow surrounding it.
●
Reliable earthing—Maintain reliable earthing of rack-mounted equipment. Pay particular attention to the supply connections
other than the direct connections to the branch circuit, for example; use of power strips.
●
Do not mount the equipment with the fan panel facing in the downward position.
