HP Integrity rx2660 Server User Service Guide

IMPORTANT:
Data Center You can have one failed fan per zone. The fans speed up to
compensate for the failed fan. If two fans fail in a given zone, you
have 30 seconds to replace the failed fan. Otherwise, the server
performs a soft shut down due to an overheat condition.
Office Friendly You can have one failed fan rotor per zone in Zone 1 or Zone 3.
The fans speed up to compensate for the failed fan rotor. If you have
two rotors fail in Zone 1 or Zone 3, or one rotor fail in Zone 2, you
have 30 seconds to replace the failed fan. Otherwise, the server
performs a soft shut down due to an overheat condition.
3. When removing fans from a Data Center server, insert thumb and forefinger into the openings
on the top of the fan and squeeze until the fan releases from the socket (1). See Figure 45.
When removing fans from an Office Friendly server, use two hands to squeeze the two latches
on the server fan (1). See Figure 46.
4. Pull the fan straight up and out of the server (2).
CAUTION: Be careful when removing fans. If you remove them while the server is receiving
power, keep your fingers away from the fan air intakes. The openings are large enough for
your fingers to contact moving fan blades. The fans are labeled as follows:
