previously removed to secure the I/O

PSU Overview
Two (2) redundant PSUs:
The subsystem is powered by with two
(2) 530W, fully redundant, hot-swappable PSUs. These modules
are accessed through the subsystem rear panel.
PSU canister:
Each PSU is housed in a steel canister which also
contains a removable cooling module. When the PSU is removed,
the cooling module is also removed.
PSU identification text:
Before you insert a replacement PSU, be
sure that it has the same identification ID text on its extraction
handle as that shown on the remaining PSU. Double-check to avoid
mixing a similar yet incompatible module from previous EonStor
series. (See
Figure 5-15
