Re: 0551/0553 rack back panel

It's there fore noise reduction. I agree about the heat and on racks
where we have 570s mounted we typically remove it allowing that heat more
easily to exit throught he perforated door. Whatever DB reduction isn't
significant in a datacenter with hundreds or thousands of spinning AMDs
and HDAs.

It probably strengthens the door a bit as well but unless you're doing
chin-ups on the thing it's going nowhere!

0551/0553 rack back panel






There's a vertical metal plate with inward-facing foam on the back door
panel of our racks. It covers roughly the center third of the panel.
Anyone have an idea what purpose it serves? Seems to me it just
restricts some airflow. The back of our rack it rather warm & I'm
wondering if the airflow would be better and system temps would be lower
if that panel was removed.

We haven't had any thermal warnings, which implies I'm ok to ignore it.
But it bugs me.
