2.7 Chassis Monitoring Module (CMM) -optional-

The Chassis Monitoring Module (CMM)
• monitors the three VME voltages
• can monitor two additional voltages with a range of ±24 V
• can monitor up to seven NTC temperature sensors
• can communicate with the Fan Control Module (FCM)
• provides 16 digital inputs
• provides 10 digital outputs
The CMM is an optional assembly and not included with the subrack by default.
The CMM is a pluggable unit in the 3 U euroboard format with a
3 U/1 HP front panel and can be assembled at the front or rear side.
The CMM allows communication and remote monitoring via RS-232 or Ethernet
interface. The front panel provides a RJ45 connector (Ethernet) an a D-Sub9
connector (RS-232).
A user interface via HTML page is available.
The CMM can monitor the 3 VME voltages and two additional voltages (up to
±24 V ). The error status can be displayed by LEDs, through the RS-232 serial
DC
interface or via ethernet as a HTML page.
Up to 7 NTC temperature sensors can be connected to the CMM.Two alarm
thresholds between 20° C and 70° C can be set.
The CMM provides 16 digital inputs and 10 digital outputs for custom specific
applications. Four digital outputs are open collector outputs, isolated by opto-
couplers, six digital outputs are TTL-compatible non-isolated.
The CMM is connected to the FCM. The temperature values and the fan speeds
are transferred to the CMM.
