Optional 48 VDC Power Supply Module

for E-MCC-1600 Chassis



Master/Slave Switch

NOTE: Power Supply Modules can be “hot swapped”.

The E-MCC-PS48 MAY or MAY NOT be shipped with the Master/Slave switch shown installed on the circuit board.

If present, the Master/Slave switch allows the Power Supply Module to be configured as the primary (master) Power Supply Module or as the secondary (slave) Power Supply Module.

If any Power Supply Module WITHOUT a Master/Slave switch is installed in the E-MCC-1600 chassis, by default that Power Supply Module is secondary (slave).

If neither Power Supply Module has a Master/Slave switch, primary/secondary status is automatic and non-configurable.

If both Power Supply Modules have Master/Slave switches and both are configured as the primary (master) Power Supply Module, each Power Supply Module contributes a portion of the power to the chassis (“load sharing”).

CAUTION: When installing a Power Supply Module that has a Master /Slave switch in a chassis with a Power Supply Module that does not have a Master/Slave switch, the Power Supply Module with the Master/Slave switch MUST BE CONFIGURED AS PRIMARY (MASTER).

When installing two Power Supply Modules that have Master/Slave switches, at least one Power Supply Module MUST BE CONFIGURED AS PRIMARY (MASTER). Failure to observe this caution could result in damage to, and subsequent failure of, Power Supply Module(s).
