Shutting down hardware components
Press and hold down the power button at the hardware component for more than 5
seconds to shut it down.
ð
The software components are being shut down. This may take approx. 5 to 20
seconds.
BSCU: The hardware component is properly shut down if the "RUN" LED
flashes quickly.
CHU: The hardware component is properly shut down if the "RUN" LED is off.
➔ You have successfully shut down the hardware components.
5.2 Switching off the DIB-R5 flexibleTx
The procedure for switching off the DIB-R5 flexibleTx is described below.
Several on/off switches with redundant power supply lines
With redundant power supply lines (optional), the DIB-R5 flexibleTx features two on/off
switches and two separate power sources, if necessary. Each of them has to be
switched off for the service interruption of the product.
Switching off the DIB-R5 flexibleTx
Preparation:
n The installed hardware components must have been shut down, refer to
Ä
Chapter
5.1 “Shutting down hardware components” on page 77.
1. Set the on/off switch to the switch position "OFF", refer to Figure 8.
ð
The integrated hardware components are switched off.
2. Switch off the power source at the site. Alternatively you can switch off the fuse of
the sub-distribution.
Risk of electric shock
Ensure by means of switch interlock that a source of electrical power cannot be
switched on unintentionally by an unauthorized third person.
3. Check whether all LED displays are inactive.
➔ You have successfully switched off the DIB-R5 flexibleTx.
