All temperature ratings shown are for sea level. An altitude derating of 1.0°C per 305 m (1.8°F per 1,000 ft) to 3,050
m (10,000 ft) is applicable. No direct sunlight allowed. Maximum rate of change is 20°C per hour (36°F per hour). The
upper limit and rate of change might be limited by the type and number of options installed. Under standard operating
support, a fan fault or the ambient temperature exceeding 30°C (86°F) might result in reduced system performance
issue.
Limited system operating temperature requirements
The maximum system operating temperature for most components installed in the server is 35°C (95°F).
However, some components in specific configurations are subject to thermal limitations. To ensure safe
and reliable system operation, observe the limited operating temperature for these configurations.
Temperature requirements for transceiver installation in the QSFP port
The following temperature values are valid for systems that have a homogenous node configuration.
