Replacing the hot-plug fan modules
V
CAUTION!
The actions described in this section may only be performed by
personnel with the appropriate technical training. Any unauthorized
openings and improper repairs could expose the user to risks
(electric shock, fire hazards) and could also damage the equipment.
Please observe the safety information in
chapter "Important
information" on page 27
.
In order to replace a defective fan, it is necessary to remove the housing cover,
because the fans are not directly accessible (see
section "Opening/closing the
housing" on page 106
).
V
CAUTION!
The housing cover must be replaced as soon as possible for purposes of
cooling, to comply with EMC regulations (regulations regarding
electromagnetic compatibility) and to prevent fires. The housing cover
must not remain open for longer than 5 minutes.
The server is equipped with one fan unit, consisting of five separate hot-plug fan
modules. The server can be upgraded with a second fan unit with five hot-plug
fan modules.
A predicted fan fault is reported by the Global Error indicator lighting up on the
front and rear of the server. When the housing cover is open, the faulty fan can
be identified by the corresponding LED (
figure 29 on page 98
) and can be
replaced while the system is running.
If only one fan unit is installed, a defective fan must be replaced immediately. If
two fan units are installed, the fans work in redundant mode, which means that
a defective fan can be replaced at the next scheduled service.
