8.1.3 Replacing hot-plug fan modules
V CAUTION!
The actions described in this section may only be performed by
personnel with the appropriate technical training. (The device can be
seriously damaged if it is opened without authorization or if repairs are
attempted by untrained personnel.)
It is essential to observe the safety instructions in chapter "Important
information" on page 25.
In order to replace a defective fan module, the left side cover (floorstand model)
or the housing cover (rack model) must be removed as the fan modules are not
directly accessible.
V CAUTION!
The side/housing cover must be reinstalled as soon as possible due to
cooling, to comply with applicable EMC regulations (regulations on
electromagnetic compatibility) and to protect against fire. The housing
must not be left uncovered for more than 5 minutes.
Therefore, make sure you are prepared to make the replacement by
unpacking the new fan module and placing it near the server.
V CAUTION!
A defective fan module may only be replaced by an identical fan module.
Hybrid operation using both redundant and standard fan modules is not
permitted.
The failure of a fan module is indicated by the CSS indicator on the front and
rear of the server (flashes yellow).
The defective fan module is indicated by a flashing LED and can be replaced
during operation. The LEDs are not visible unless the housing is open.
Ê Open the server (see section "Opening/closing the housing" on page 111).
