Replacing a Power Supply Unit (page 68)
Power Supply
The redundant power supply provides the system with power. It
is a reliable and enduring part of the system because it consists
of several independent power supply units: Even if one fails the
others will still offer enough power to keep the system working.
When a power supply unit failure occurs, you will be notified by a
lit alarm LED and the sounding of an alarm buzzer of the system.
The alarm can be switched mute with the mute button at the
front of the system (see section “Operation Items” on page 23).
Each power supply unit in the R&S DVS system is hot-swappable,
so you can safely replace it with the system running.
System Damage
The system can be operated with one power supply
unit out of order. However, if another one fails, a
continued operation of the system cannot be guar-
anteed.
Change a failed power supply unit immedi-
ately.
Alarm
An alarm can be caused by a number of reasons.
Please refer to section “Troubleshooting” on
page 74 first for further details about what to do in
case of an alarm.
For an overview of a power supply unit see section “Pow-
er Supply” on page 44.
