sists of several independent power supply units:
Even if one fails the other will still offer enough power to keep the sys-
tem working.

your system will be inoperable. Change a failed power supply
unit immediately (see section “Power Supply Maintenance”

ther with their LEDs as explained below or with the general
alarm LED (see section “Operation Items” on page 2-6).
