DXS-3610 Series Layer 3 Stackable 10GbE Managed Switch Hardware Installation Guide
17
A second DC PSU module can be installed into the second PSU module slot labelled PSU-2. If the primary DC PSU
fails, the second DC PSU is used to provide DC power to the Switch. This takes place immediately and automatically.
Installing Fan Modules into the Fan Module Slots
This section guides the user through installing fan modules into the fan module slots. On the rear panel of the Switch,
there are five fan module slots. Front-to-Back (FB) or Back-to-Front (BF) fan modules can be installed in these slots.
By default, the Switch is shipped with five DXS-FAN200 modules pre-installed.
NOTE: The fan modules support a specific airflow direction. This airflow direction must be the same as
the PSU module(s) installed. The default airflow direction is front-to-back on all the installed PSU
modules and fan modules.
To remove an existing fan module, use a flat-head screwdriver to unscrew the lag bolt (with a slot drive head) and
gently pull the fan module out of the fan module slot.
Insert the new fan module into the fan module slot and fasten the lag bolt to secure the fan module into place.
