Certain double-conversion UPS units by Liebert (in my case — a GXT4-2000RT120) appear to contain a boobytrap whereby off-the-shelf (needs two 12v/80mm) high-efficiency/quiet fans will not operate — the boot will abort with a Fan Out of Order error.

The 2021 Rack.

Thank you, 2020 Rack Service subscribers! I would like to wish all of you another great year of hygienic Linux on high-quality non-Fritzed iron! The 2021 service agreement is identical to the 2020 one. With the unfortunate exception that Deedbot Wallet is closing down on Dec. 25, 2020, and hence will no longer be accepted […]
