6 Error Indication
The indication of an error is realized via hardware, i.e. via red LEDs and additionally
via software, i.e. via Web Interface, via an SNMP trap, or by polling the
corresponding SNMP object(s). The hardware indication via LEDs is described in
chapter 3.1.1. The indication via Web Interface is subject of chapters 5.4.3 & 5.4.5;
the indication via SNMP is explained in chapters 5.5.4.1 & 5.5.4.4. The software
error indication (i.e. the error codes) is described in the following.
6.1 Software Error Indication
The device is capable to detect several types of errors that are reported to the Web
Interface and to the M&C system. Either the M&C system has to poll the device for
these errors or it is informed via an alarm trap, assuming that the specific SNMP
trap is enabled.
6.1.1 LED Unit Error
The communication with the LED unit at the front of the device is monitored and a
corresponding error is reported in case of a failure.
6.1.2 Amplifier Errors
Two amplifiers are installed in the DEV 2194. The different functionalities of the
amplifiers are monitored. Error indication is provided for the communication with
the amplifiers, for the temperature, for the amplifier supply current, for the RF
level functionality, and for the LNB power (or bias) current monitoring functionality.
Amplifier [i] (i = {1…2})
Overtemp Module [i] (i = {1…2})
Overcurr Module [i] (i = {1…2})
RF Sense Port [i] (i = {1…2})
Bias Limit Port [i] (i = {1…2})
6.1.3 Other Errors
For the sake of completeness, the other error codes that might be reported by the
device are listed here. If experiencing one of these errors, please contact
DEV Systemtechnik for assistance.
