Cooling Recommendations

OS6855-14 and OS6855-U10 switches are convection-cooled using finned heat sinks. Although air flow is
not mandatory for switch operation, the best way to ensure proper cooling is to provide some ambient air
flow over the heat sinks whenever possible (e.g., from room fans, etc.).
Reduced Air Flow
Installation of the equipment in a rack should be such that the amount of air flow required for safe
operation of the equipment is not compromised.
Elevated Operating Ambient Temperatures
If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environ-
ment may be greater than room ambient. Therefore, consideration should be given to installing the equip-
ment in an environment compatible with the maximum ambient temperature (Tma) specified by the
manufacturer.
