Installing Power Modules into the Power Module Slots
The power supply modules are hot-swappable and can be replaced during operation as long as the remaining module
is installed and operating.
Depending on whether you plan on positioning the ports in a hot or cold aisle, you can order a power supply module
with port-side intake or port-side exhaust airflow.
The power module slots, located on the rear panel of this switch, support two types of power supply modules.
DXS-PWR550AC
: 550W AC modular power supply with front-to-back or back-to-front airflow.
DXS-PWR800DC
:
800W DC modular power supply with front-to-back or back-to-front airflow.
NOTE:
The power modules support a specific airflow direction. This airflow direction of the
installed power module(s) must be the
same
as the fan module(s) installed.
By default
the
airflow direction of the power module and fan module installed is
front-to-back
.
Caution:
If the switch is installed for
port-side exhaust
airflow, you must install
green-labeled
PSU
modules to drive the air flow from the front of the switch into the hot aisle. If the switch is installed for
port-side intake airflow
, you must install
blue-labeled
PSU modules to drive the air flow from the
rear of the switch and out into the hot aisle. Failure to install the switch with the correct airflow
configuration can cause the switch to overheat and shut down.
