MCPA Module Alarms
MCPA 1900 MHz 90 Watt MCPA Product Manual
MCPA Module Alarms
All module alarms that occur in a Hitachi MCPA subrack are routed to the Alarm Interface
Block Module and are identified as either a major or a minor alarm; and then the appropriate
alarm signal is sent to the Alarm Interface Block connector. The Alarm Interface Block
connector is a DB-9 female and has both normally open (NO) and normally closed (NC)
wiring points that notify the NOC of the presence of major or minor alarms in the MCPA
subrack.
When the alarm circuit for the MCPA system is connected to the Alarm Interface Block, the
NOC receives an alarm severity notification through the relay interface. Determining which
specific module contains a fault condition can only be done when a technician is on site.
Once on site, the technician can identify which module is in an alarm condition by checking
the LEDs on the individual subrack modules. The technician can also obtain additional alarm
information for the MCPA Amplifier Module by using the Hitachi MCPA Monitor software.
To avoid damage to the MCPA module, major alarm conditions cause the MCPA module to be
automatically shut down.
When the MCPA module detects a minor alarm, it continues operating. The dry-contact relay
is open when an alarm condition is detected through the Alarm Interface Block connector.
Depending on the alarm, the MCPA module either automatically recovers or may require a
reset.
Note:
You can view alarm details using the MCPA Monitor software. Refer to the “MCPA
Monitor Windows” on page 5-3.
Note:
The notification method to the BTS for all the alarms is dry contact.
