Replacing the IDTEMP combo
This board includes two important system components:
– EEPROM for the chassis ID and ident number of the server
– temperature sensor for monitoring the environment temperature
The data for the EEPROM, and the current temperature values as well, are
transmitted to the system board via the connected I
2
C bus.
The IDTEMP combo must be correctly installed in order to run an exact temper-
ature monitoring, to project the front end in the server management or install the
server using
ServerStart
.
The information provided on the IDTEMP combo must not be altered.
Exception: If the chassis version is converted from floorstand model to
rack model, the server identification must be revaluated in order to match
the image displayed in the server management system (ServerView).
The IDTEMP combo may not be changed because of the informations
which are in the EEPROM to identify the system.
If the combo is defective, a spare part must be ordered specially by
specifying the ident number (see type label).
The IDTEMP combo is situated on a separate holder under the SCSI hard disk
cage.
Requirements
– server has been switched off
– power cords have been disconnected
– left side cover has been removed
