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 infor-

The server has two redundant fan units (1+1). Each fan unit consists of two
separate hot-plug fans. The fans are only accessible when the server is open.
A possible fan fault is reported by the CSS indicator lighting up on the front and
rear of the server or displayed on the ServerView Local Service Display (for
more information about the behavior of these indicators, see chapter “Starting
up and operation” on page 55 and the "Customer Self Service (CSS)" manual
on the ServerBooks DVD).

ServerBooks DVD).
When the server is open, the faulty fan can be identified by the corresponding
LED (see figure 24 on page 87) and can be replaced while the system is
running.
