Information icon definitions:

WARNING:The Warning icon signals information about hardware handling that could result in injury.

CAUTION:The Caution icon signals information about situations that could result in equipment damage or loss of data.

NOTE:The Note icon signals important operational information.

Warnings

WARNING:Only trained and qualified personnel can install this equipment. Read the safety instructions in your Safety, Environmental, and Regulatory.

WARNING:To avoid electrostatic discharge (ESD) damage, wear grounding wrist or heel ground straps when handling this equipment. After you remove the original packaging, place the PowerSwitch S4300-ON Series and its components on an anti-static surface.

WARNING:This switch has multiple power cables. Disconnect all power cables before servicing.

WARNING:This switch has optical transceivers, which comply with the limits of Class 1 laser radiation. When working with optical fibers, follow all 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.

WARNING:When no cable is connected, visible, and invisible laser radiation may be emitted from the aperture of the optical transceiver ports. Avoid exposure to laser radiation; do not stare into open apertures.

WARNING:Always install all fan modules before you power on the switch.

WARNING:Prevent exposure and contact with hazardous voltages. Do not attempt to operate this switch with the safety cover removed. To comply with the GR-1089 Lightning Criteria for Equipment Interfacing with AC or DC Power Ports, use an external surge protection device (SPD) at the AC or DC input of the router.

WARNING:Equipment that provides DC input to the DC port must be Certified for China (CCC) and meet the relevant standards.

Cautions

CAUTION:Operate the equipment at an ambient temperature not higher than 45°C (113°F).

CAUTION:Dell Technologies recommends you ground your switch. Use the switch in a common bond network (CBN). Grounding conductors must be made of copper. Copper conductors offer better conductivity and durability. Do not use aluminum conductors. The ground cable must be 10 AWG minimum. The nominal thread diameter screw type is 4.0 mm (0.157 in). Coat the one-hole lug with an antioxidant compound before crimping. Bring any unplated mating surfaces to a clean finish and coat with an antioxidant before mating.

CAUTION:For AC-powered switches, although the third conductor of the AC power cable provides a ground path, Dell Technologies recommends grounding your switch with a dedicated ground wire. Using a dedicated ground wire reduces equipment communication interference, offers ESD protection, and prevents possible equipment damage.

CAUTION:For AC-powered switches, the main power disconnect device is the power supply cable. Ensure that the socket outlet is located or installed near the equipment and is accessible.

CAUTION:For DC-powered switches, the only way to safely ground your switch is to attach a dedicated ground wire. The ground lug ships inside the DC PSU shipping box. The two ground lug screws ship attached to the switch. Before you power on the DC switch, ensure that the ground lug and ground wire are properly attached to the switch and the earth ground.

CAUTION:This switch must be supplied by a DC power source minimum to maximum input of -40 Vdc to -72 Vdc, 40 A minimum, and Temperature Maximum (Tma) = 45°C ambient. The altitude of operation is 3048 m. The product must be supplied by a UL-Listed DC power source that is separated from AC mains by double or reinforced insulation when the switch is connected to DC power. For more information, contact your Dell sales representative.

CAUTION:To avoid tangling cables or damaging optics, install the switch into a rack or cabinet before installing any switch components.

CAUTION:To avoid damage to the switch, fan and PSU airflow directions must match. Do not mix normal and reverse airflows in a single switch.

CAUTION:Do not mix AC and DC PSUs in the same switch.

Notes

NOTE:If necessary, to upgrade your software or firmware images, go to the Drivers and Downloads page of your switch at Dell support.

NOTE:For proper ventilation, position the switch with a minimum of 12.7 cm (5 in) of clearance around the exhaust vents.

NOTE:Do not use the mounted rails as a shelf or workplace.

NOTE:A region specific AC power cable is included to power on an AC power supply. You must order all other power cables separately.

NOTE:For Restriction of hazardous substances (RoHS) information, see Restricted Material Compliance.
