Hardened PoE PSE Switches from Black Box power remote PoE devices such as security cameras and wireless access points-even in industrial or factory environments where temperature is an issue. Rugged metal cases serve as a heat sink to dissipate heat, giving these hardened switches a temperature range of -13 to +140° F (-25 to +60° C). Plus, the cases are sealed to resist contaminants such as dust, dirt, moisture, smoke, and insects. These capable industrial switches are available with six 10-/100-Mbps copper ports, with five 10-/100-Mbps copper ports plus a 100-Mbps fiber uplink port, or with four 10-/100-Mbps copper ports plus two 100-Mbps fiber ports. Fiber ports are available with a variety of connectors, in single- or multimode, and with ranges of up to 20 kilometers. The switches provide 802.3af PoE power for up to four PoE PD devices on four RJ-45 ports.
