D.5.3 First Stage - “Other Common Issues and Solutions”
The first stage when facing an issue is:
•
Section D.4 “Other Common Issues and Solutions” on page 231.
Review the information in this section which lists some common issues and provides
solutions.
This may resolve your issue.
•
If this does not resolve your issue,
then proceed with the guidance provided in the following sub-sections, see section
D.5.4 “2nd Stage, Fault Identification - Power Supplies” on page 236 onwards.
D.5.4 2nd Stage, Fault Identification - Power Supplies
The Vega-MV frame is designed to operate with a nominal 24VDC internal supply and will
operate over a range of DC supply voltages.
However, if the DC supply voltage drops too low, the first effect will be to stop the fan system
operating over its full range. If the Vega-MV’s thermal monitoring system detects any resulting
overheating it will send out alarm messages and begin a phased shut-down of the chassis.
This will affect the normal operation of the chassis.
Resilient MV-NET card processor:
The processor on the MV-NET card has been designed to be resilient and still operate at a
very low DC supply voltage. Thus the processor can provide front panel LED, OLED and
on-screen-display (OSD) indications of any detected fault conditions.
There are two procedures presented in the document:
•
Section D.5.4.1 “Procedure 1 - Checking Status LEDs” on page 237
•
Section D.5.4.3 “Procedure 2 - Front Panel P1 LED is RED or Flashing” on page 243
