Saturday: A POE injector blew, this POE injector powerd the ProCo Momentum at the drum kit. Also, when this blew, it took out 2 ports on the LAN switch (ports 47 & 48). Port 48 ran the connection to the FOH, so with this port dead the entire system was down.
We removed the POE injector and moved the lines to different ports. We actually moved all 4 to a new bank, to avoid any possible issues from the bank that was damaged.
The system is back online now and appears to be working normally. It is possible this POE injector was causing some of the previous issues (documented below)
Sunday: the ProCo Momentum had some issues and below is the sequence.
- After discovering no audio from the FOH loudspeakers, the Momentum control software was started and in the “synchronization” page, at least one of the Momentum units was shown as “offline” (I believe it was the mo8 that is connected to the amps in the backstage rack).
- So, we went backstage and took a look to see if something had become disconnected or messed with. All looked connected, but the mo8 had all 8 of its “signal/clip” LEDs flashing green (all at once about once a second). I wish I would’ve looked at the other LEDs and display, but I didn’t.
- At that point, we turned off everything on the sequencer and restarted it. Everything powered up and “looked” normal from the indicators on the front and back of the mo8, but no sound was being feed to the amps.
- Again, we opened up the Momentum control software and told it to take all the settings from the network (instead of sending the file settings to it). Then we discovered that it appeared that all the momentum units had been set to default/factory settings.
- We then proceeded to re-synchronize, but used the settings file on the laptop to send the settings to all the Momentum units. From there on out, it worked flawless.
Sunday 7/31/2011: an issue occurred during the service where a portion of the instruments were “lost” or somehow muted. In that situation, no data is known to really pinpoint if it is a ProCo issue, a network (switch or cable) issue, or something else.
