GND: Terminal for “earth” or ground wire connection to the 6K8-Series chassis

Input Voltage: 18 to 36 VDC (24VDC)

Input current: 0.6Amps max.(for all RJ-45 ports)

Input current: 1.2Amps max.(for all Fiber ports)

Input Voltage: -36 to -70 VDC (-48VDC)

Input current: 0.4Amps max.(for all RJ-45 ports)

Input current: 0.7Amps max.(for all Fiber ports)

Input Voltage: 88 to 300 VDC (125VDC)

Input current: 0.1Amps max.(for all RJ-45 ports)

Input current: 0.125Amps max.(for all Fiber ports)

Power Consumption: 25 watts max., for fully loaded (fiber ports)

(24V, -48V, 125V)DC 8 watts typical for all (RJ-45 Ports)

into the switch. This allows the Switch to operate only whenever DC power is correctly applied to the two inputs. It protects the Switch from incorrect DC input connections. An incorrect polarity connection, for example, will neither affect the Switch, its internal power supply, nor will it blow the fuse in the internal power supply.

 

The manual power “On-Off” Switch (optional) is used for powering the unit on

and off when it is placed into or taken out of service.
