[dsg-hallb_rtpc] RTPC crates

[Brian Eng]

I've never done the firmware on this piece of equipment so honestly I have no idea.

Hello Brian,

How long does it take to have firmware update? Can you please give me an estimate? I am at hall so that I could power off everything safely.

Thank you,
Jiwan

Yes, the CVT insertion cart.

Previously it housed only SVT stuff: https://www.jlab.org/div_dept/physics_division/dsg/album/HALL%20B%20SVT/Installation%20for%20noise%20test%20in%20Hall%20B/SVT%20electronics%20rack%20structure%20relocated%20in%20Hall%20B.jpg

It has since been modified (top half removed) and now houses MVT stuff as well, I guess that's when it got renamed.

Let me know once everything has been put into a safe state.

Sorry for the cross chatter - when you say “SVT cart”, do you mean the CVT insertion cart? As Jiwan points out, there are FEU LV and cooling fan supplies, among other things, on the latter. We may have to power down the FEUs safely.

Hi Mohammad,

Is the RPTC using anything on the SVT cart that requires AC power?

The remote power strip has a vulnerability that requires a firmware upgrade to fix and I'm not sure if applying this will cause any power loss.

So obviously we'd want to do this when nothing is being actively used.

Thanks
Brian
