Hot Swapping
Hot swapping allows you to replace one failed power supply while the other provides full power. This
makes it unnecessary to shut down the Mobility Master hardware appliance during the replacement
procedure.
Hot swapping is supported only when power redundancy is in effect. This requires that after the
target power supply is removed, the device’s total power load does not exceed the combined rated
output of the remaining power supplies.
LED Indicators
The following table shows the LED indicators and the corresponding status:
Grounding Point
To meet safety and electromagnetic interference (EMI) requirements and to ensure proper
operation, the appliance must be adequately grounded before power is connected. Connect a
grounding cable to earth ground and then attach it to the chassis grounding point using two screws.
Comply with electrical grounding standards during all phases of installation and operation of the
product. Do not allow the appliance’s chassis, network ports, power supply, or mounting brackets to
contact any device, cable, object, or person attached to a different electrical ground. Also, never
connect the device to external storm grounding sources.
