RES-22XR3 Installation Manual - Configuration 1 Version 1.3
2.1.6 Removable 80-mm Fan
The RES-22XR3 contains three 4-wire high-speed 80-mm fans. All fans are hot-
swappable in case of a fan failure. See
Figure 2-11 on page 2-12 for fan layout and
descriptions.
Note: Since RES-22XR3 fans are “hot-swappable”, it is not necessary to turn off
system power in order to remove and replace a fan.
Caution: When replacing the 80-mm fans, do not leave the fan lid open for more
than 3 minutes, as this will cause an undesirable drop in chassis pressure (bad for
temperature stability). In the event of a catastrophic fan failure (all fans cease to
function) it is highly advised that the system be powered down, then take action to
replace the fans.
Only pull the chassis as far as needed to fully access the fan lid. Doing so will help
prevent accidental removal of any cables attached to the rear I/O.
