Summary alarm configuration
The SATCOM6 enclosure is equipped with the summary alarm indication by mean of two external LEDs. Green indicates normal
operation, and red indicates an alarm condition in one or more of the slots. No light indicates a power failure. Alarm circuitry is open
drain type, requiring each unit to actively pull down to indicate normal mode of operation. In such circuit topology an empty slot would
raise an alarm. To prevent such a situation DIP switch SW1 should be set according to the configuration
, switch to ‘USED’ position if
the slot is occupied ‘EMPTY’ if the slot is unoccupied. The switch allows masking of alarms from any of the 6 main slots or the 2
additional LNB slots.
5.3
SNMP card configuration
SATCOM6 can be monitored and controlled via a web browser or SNMP management system. Before first use the system has to be
configured. Refer to HRC-1 handbook to find more details about the set-up process.
5.4
Fan operation
To allow reliable operation under harsh environmental conditions the SATCOM6 is equipped with two fans enabling internal air
circulation. The speed of the fans is dependent on internal temperature. D6 LED indicates the status of the fans.
