LED indicators
•
Identification LED
In the CHC web interface, select Maintenance tab and click Identification LED. This
gives you an option to switch On/Off the identification LED of QSM.
•
Power LED
The power LED indicator is bicolor: Amber/green indicating the power state:
−
Amber: 3.3V stand-by power presence
−
Green: 12V main power presence
•
IB link activity LED
There are two LEDs:
−
Physical link -green indicates a good physical link. Blinking indicates a problem
with the physical link data activity.
−
Logical link -Amber blinking indicates data transfer.

Ultra Capacitor Module
The UCM is an optional module that can ride through AC outages of a maximum of
250ms. During normal operation, the module gets charged by the12V from the Midplane
and stores the charge it in its Ultra capacitors. During outage, these capacitors discharge
to provide the required power to the other modules like the NCB and the Quad Switch
Module board (QSB). For 3v3 stand-by voltage, the PSU module has a hold time of
1000ms. Hence, the PSU module itself takes care of the 3v3 during the 250ms AC outage.
The UCM connects to the Midplane through bus bars. In addition, there is control and
monitoring logic that is controlled by the CMM. The control/monitoring logic operates in
3v3 standby voltage from the PSU module.
