Figure 4.6.3-1 PSU Installation
NOTE
Turn OFF the PSU in the EKSU(s) then turn OFF the PSU in the BKSU. If the PSU in
the BKSU is turned OFF first, the system will automatically remove power from the
EKSU.
The 1st and 2nd KSUs will work independent of the 3rd KSU (power shut OFF).
The 1st KSU will work independent of the 2nd KSU (powered OFF); however, the 3rd
KSU cannot work without the 2nd KSU powered-ON.
It is recommended that the iPECS-MG be reset if the PSU to an EKSU is power cycled
or turned OFF.
