8.1.3 Replacing a hot-plug fan
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.
It is essential to observe the safety instructions in chapter
“Important information” on page 25.
In order to replace a defective fan, it is necessary to open the fan cover, because
the fans are not directly accessible.
The server is equipped with five fan units. Each fan unit consists of two separate
hot-plug fans.
A possible fan fault is reported by the CSS indicator lighting up on the front and
rear of the server or displayed on the optional ServerView Local Service Panel
(for more information about the behavior of these indicators, see chapter
“Startup and operation” on page 57 and the "Customer Self Service (CSS)"
manual on the ServerBooks DVD).
When the fan cover is open, the faulty fan can be identified by the corresponding
LED (see figure 29 on page 100) and can be replaced while the system is
running.
