Preparing your system for upgrade
Note the following, when installing or replacing devices, to improve the performance of this server.
•
With this server, optional devices can be replaced during the continuous operation.
Take extreme care for electric shock and damage to the component due to short-circuit.
•
Optional devices cannot be installed or removed during continuous operation.
After shutting down OS, check that the server is powered off, disconnect all power cords and interface
cables from the server before installing or removing the optional devices.
•
To remove the CPU/IO module during the continuous operation, disable the intended module (place the
module off-line) by using either of the following methods:
–
ft server utility of the NEC ESMPRO Agent
–
NEC ESMPRO Manager from the management PC on the network
After a new module is installed to the server, enable the module using the ft server utility or the NEC
ESMPRO Manager.
Tips
The system is defaulted to automatically boot the module, once installed.
•
Make sure to provide the same hardware configuration on both CPU/IO modules (except SAS board).
•
Use the same slots and sockets on both groups.
•
Do not install those devices having different specifications, performance, or features.
•
Before removing the set screws from the CPU/IO modules, place the desired module off-line using the ft
server utility or the NEC ESMPRO Manager.
