Hot-plug Memory Boards
V
CAUTION!
The actions described in these instructions should only be
performed by technical specialists. Equipment repairs should only
be performed by authorized, qualified staff. Any unauthorized
openings and improper repairs could expose the user to risks
(electric shock, energy hazards, fire hazards) and could also
damage the equipment.
Please observe the safety information in chapter “Important Notes”
on page 15.
The following operations are possible while the system is running:
–
Hot-replace: Replacing defective memory boards (see “Removing a Hot-
plug Memory Board” on page 81 und “Inserting a Hot-plug Memory Board”
on page 83)
V
CAUTION!
Hot-replace during system operation is only possible if the memory
boards are in a redundant configuration in
BIOS setup
. This means
they must either be in mirroring mode or in RAID mode.
–
Hot-add: Inserting new memory boards into empty slots (see “Removing the
Dummy Module” on page 82 und “Inserting a Hot-plug Memory Board” on
page 83)
V
CAUTION!
If mirroring mode or RAID mode is not specified in
BIOS setup
, hot-add
during system operation is only possible if "maximum compatibility" in
configured in
BIOS setup
.
I
Additionally, hot-add and hot-replace must be supported by the operation
system. If the above conditions are not fulfilled, no hot-plug operations
are possible. The server must then be shut down before the operation
can be started.
Only memory boards of the same type and the same settings may be
replaced or added. The new memory board will not be put into operation
if the configuration is not consistent.
Replacing and adding DIMMs to the memory boards is described in the
Options Guide.
