1.4.2 PWR

I. Functions
The power supply system of the Eudemon200 firewall comprises two PWRs. In normal
situations, the two PWRs (either supplying DC or AC power) function in a redundant
way. The input interruption or failure of a PWR will not affect the operation of another
PWR, and the operating PWR will supply all the power required by the system.
The Eudemon200 firewall provides two types of PWRs, i.e., AC-input PWR and
DC-input PWR, both providing the output power of 350W. AC-input PWR module uses
PSR350-A power supply, and each power module provides an output power of 350W.
The two-way outputs are combined on the backplane. DC-input PWR module uses
PSR350-D power supply, and each power module also provides an output power of
350W. The two-way outputs are also combined on the backplane. Power cable uses
D-type 3PIN -48V feeder cable. PWR has the functions of overcurrent protection and
overvoltage protection.
You can connect the PWR to the backplane by inserting it from the rear of the
Eudemon200 chassis. It is hot swappable and its switchover will not affect the ongoing
system operation.
