CHAPTER 3 Component Configuration and Replacement (Add, Remove)
3.3 Replacing components
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
Since there may be a time deviation after the Home SB is replaced, set the time in the operating system
when the NTP is not used.
Memory Scale-up Board
Memory Scale-up Board can be replaced when partition including the Memory Scale-up Board is powered off.
Remarks
Since the Mezzanine/DIMM which is mounted on the Memory Scale-up Board can be replaced after removing
the Memory Scale-up Board from the device, the replacement can be done under the same conditions as the
Memory Scale-up Board.
IOU_1GbE/IOU_10GbE
If the DR function (IOU hot remove and IOU hot add) is used, the IOU_1GbE and IOU_10GbE can be
replaced even if the partition that uses the IOU_1GbE/IOU_10GbE is powered on. If the DR function is not
used, then the replacement is possible when the partition that uses the IOU_1GbE/IOU_10GbE is powered
off.
For PXE boot, re-configuring of boot order is required after replacing IOU.
For details of re-configuring of boot order, see '3.3.2 Boot specification of UEFI' in the "PRIMEQUEST 2000
series Tool Reference' (CA92344-0539)
DU
DU can be replaced when the status of the partition that uses the DU to be replaced is powered off.
MMB
In a system with two MMBs installed, hot replacement can be used to replace an MMB when the system
continues operating. Basically, the faulty MMB (Standby MMB) can simply be replaced since a faulty MMB
would have been switched with a standby MMB. To replace the active MMB, switch it with the standby MMB
before replacing it. The replacement does not affect control and monitoring in the system.
