Ventilation
This XC5100 has forced air flow from front to back allowing for multiple units to be stacked above each other
with no space in between. However, adequate space must be provided in front of and behind the unit for
effective ventilation.
The XC5100 has 6 fans in front. Fan speed is temperature controlled. If one fan fails, remaining fans will increase
speed to compensate. The whole Fan module, containing all 6 fans, can be hot swapped. If, during fan module
replacement, the temperature on the inserted modules exceeds a certain critical temperature, the unit will shut
down, to prevent damage of the inserted modules.

Replacing the power supply module
This 1RU chassis can be installed with one or two hot swappable power supply modules. The modules can be
exchanged from the rear of the unit. The chassis delivered with a single power module can be updated by
acquiring additional power module.
If power is lost in one of the Power supplies, the other can feed the entire chassis. It is recommended to connect
each input power at different circuits.
