Fan Tray

This section describes you how to remove and replace a fan tray in both the Netra
CT 810 server and the Netra CT 410 server.
If the temperature rises above 158˚F (70˚C), the CPU card sends out a warning that
the system is overheating. If the temperature rises above 167˚F (75˚C), then the
system shuts down automatically. Note that the temperatures above are not ambient
air temperatures, but rather the CPU temperatures that are monitored by a
thermistor located under the heatsink on the host CPU card.
If one fan tray fails, you must replace the failed fan tray as soon as possible. Even
though the system can run on one fan tray, if the temperature rises, a single fan tray
may not be able to cool the system properly.
