*5: DR function is required.
3.3.2 Component replacement conditions
This section describes the replacement conditions of each component.
PSU
The PSU unit can be replaced while the system continues operating. PSU replacement in a non-redundant
configuration requires the system to be stopped.
FAN
The FAN unit can be replaced while the system continues operating.
SB
If the DR function (SB hot remove and SB hot add) is used, the SB can be replaced even when the partition
using the SB is powered on. When the DR function is not used, the SB can be replaced if the partition using
the SB is powered off.
Remarks
Since the CPU/Mezzanine/DIMM/PCI Express card /FBU which is mounted on the SB can be replaced after
removing the SB from the device, the replacement can be done under the same conditions as the SB.
Note
