Hi guys,
So earlier today, one of the three VPRO boards (VPRO <Y>) at my site was found powered off. We discovered this after the following alarms:
* TCP Minor Trouble
* VPRO Communication Fault
* RST Slot-1 VCMI Diagnostic Alarm
Since I was not physically at the site today, I did not get to dig around further. I will be doing that tomorrow and will share the results accordingly. However, since the VPRO <Y> was found powered off, I don't think it would be wrong to assume that the board is done for and that a replacement is in order.
My questions is therefore with regards to how I can go about replacing it safely while my turbine is running.
This is the procedure I found in GEH-6421 Vol. 1.
<i>1. If a VCMI or VPRO has failed, the rack should be powered down,
and the IONet connector unplugged from the board front, leaving the
network still running through the T-fitting.
2. Loosen the top and bottom screws on the VCMI board.
3. Use the upper and lower ejector tabs to disengage the controller from the backplane.
4. Remove the VCMI and replace it with a spare VCMI.
5. Use the upper and lower ejector tabs to install the new VCMI board.
6. Tighten the top and bottom screws to secure the new VCMI or VPRO to the VME rack.
7. Power up the VME rack.
8. From the toolbox Outline View, under item Mark VI I/O, locate the failed rack.
Locate the VCMI, which is usually under the simplex rack, and right-click the VCMI.
9. From the shortcut menu, click Download. The topology downloads into the new board.
10. Cycle power to the rack to establish communication with the controller.</i>
The procedure above says to power down the entire rack. I figured I would just remove the power to VPRO <Y> from the PDM but there is also the question of downloading after replacement. Wouldn't downloading lead to the entire VPRO rack i.e. <X>, <Y> and <Z> rebooting? Also please clarify step number 10, if possible. Why do I need to cycle the power after I have already powered up the rack and downloaded?
Please let me know if it is wise to do online or should I get Operations to take the turbine on FSNL? The latter depends on site load.
Looking forward to your responses. Thanks.
