LED Indications in Normal Operation
LED
Color
Status
PI (=Power Input)
Not lit, dark
+12V power input to the board not OK
Green
+12V power input to the board OK
PF (=Power Failure)
Not lit, dark
power generation on the board itself is OK
Red
power generation on the board itself is erroneous
FLT (=FauLT)
Not lit, dark
no other fault or error situation, different from PF, is active on the module
Red
a fault or error situation, different from PF, is active on the module
ACT (=Active)
Not lit, dark
This CSM is the standby/passive CSM in case of CSM Redundancy
Green
This CSM is the active CSM
CAUTION: At installation time, if the spare LED (for CSM310-A) or the ACT LED (for
CSM540-A) on both redundant CSMs are lit together, it means that both CSMs are active
at the same time. This is not allowed! Make sure that both CSMs are plugged in properly.

Reset Button - Factory Default - Reboot Node
This pushbutton is hidden and accessible through a small hole on the front panel. When
pushing this button, it must be pushed with a fine non-conductive
object e.g. a toothpick…
Push short
: Warm restart:
Single CSM
: Pushing the RESET button forces a warm start of the CSM without affecting
the CSM configuration;
Redundant CSMs
: Pushing the RESET button on…
… both CSMs simultaneously force a warm start without affecting the CSM
configuration, the CSM that was active before the reboot becomes the active one
again after the reboot;
… the Standby/Passive CSM forces a warm reboot of this CSM only, the other active
CSM keeps up and running to keep the node alive;
… the Active CSM initiates a switchover. The current active CSM
will warm reboot
and the other standby CSM takes over and becomes the active one to keep the
node alive.
Push long
: Warm r factory default settings:
Single CSM
: Pushing the RESET button for at least seven seconds forces a warm start
or reboot of the node and reloads the CSM and its micro SD memory card (see §2.3.4)
with factory default settings. As a result, reloading the CSM configuration from
HiProvision will be necessary;
Redundant CSMs
: Pushing the RESET button for at least seven seconds…
…on both CSMs simultaneously affects the entire node. The node reboots and both
CSMs get a new default configuration as described for a single CSM. The CSM-1
becomes the active one by default;
