Chapter 1 Maintenance
Temperature/voltage error occurs on the CPU/PCI modules

 At the time when a temperature or voltage error occurs on CPU/IO module, necessary actions will
differ depending on their status as shown below. You can check the status of each module from
the Information of server state/constitution of NEC ESMPRO Manager or ft Server Utility.
The detail information of alert is displayed as "Unknown":

 Detail information of some alert displayed on the AlertViewer may be displayed as "Unknown".
The display of ft Server Utility is incorrect:

 If you open ft Server Utility immediately after the system starts up, the tree under the CPU module,
PCI module, and/or SCSI enclosure may not be displayed correctly because the data construction
has not been completed. Wait for a while, and start ft Server Utility again.
Module status is shown "Fault":

 PCI modules (IO modules) and modules under the SCSI enclosure have impact on each other.
For example, when the "Status" item of a module changes to "fault", it may be caused by other
module error. Check the status of the other modules referring to alert message.
Temperature/voltage error occurs on the CPU/PCI modules:

 At the time when a temperature or voltage error occurs on CPU/PCI module (CPU/IO module),
necessary actions will differ depending on their status as shown below. You can check the status
of each module from the Information of server state/constitution of NEC ESMPRO Manager or
ft Server Utility.
 Remove the disk in the following procedure.
1. If the status is "Empty", the module is not mounted. Sensor monitoring is not conducted.
2. If disks are mounted on PCI modules (I/O modules), the status of both modules is "Simplex"
while the disks are mirrored. Temperature or voltage error occurring during disk mirroring will
result in the system to shutdown.
The status of network port is displayed as an error:

 For the network ports, connect the unused port of both PCI modules (IO modules) with a cross
cable.
Alert notification of monitored events

 In SNMP alert, the message text length is limited to 511 bytes. If the message text exceeds 512
bytes is sent, you need to verify the full length message on Event Viewer of sender machine. To
display the message text exceeding 512 bytes on Alert Viewer, use TCP/IP In-Band.
Status
Duplex
Other than Duplex, Empty

Tips If the status is "Empty", the module is not mounted. Sensor monitoring is not
conducted.

If disks are mounted on CPU/IO modules, the status of both modules is "Simplex"
while the disks are synchronizing. Temperature or voltage error occurring during disk
mirroring will result in the system to shutdown.
Status
Duplex Stop the failed CPU/PCI module (CPU/IO module).
Simplex Shutdown the system.
