3.2.1 Fan Tray Module
The Fan Tray module contains four integrated fans which cool the device's internal
components. The Fan Tray module draws in air through a perforated grill on the left side of
the chassis. The incoming air passes through the entire set of modules, cooling each one,
and then exits the device through perforated vents on the right side of the chassis.
The front panel of the module provides a label showing the chassis slot assignments for the
different modules.
3.2.2 Power Supply Modules
The chassis houses up to two Power Supply modules for providing power load sharing and
AC power redundancy in case of failure of one of the Power Supply modules. Each module
provides an AC power inlet on the rear panel of the chassis for connection to an electrical
power outlet.
3.2.2.1 Power LED Description
Each Power Supply module provides a POWER LED on its front panel which indicates the
status of the power supply, as described in the table below.
