Preparing Your System For Upgrade - NEC N8800-149F User Manual

PREPARING YOUR SYSTEM FOR UPGRADE

Note the following, when installing or replacing devices, to improve the performance of NEC
Express5800/ft series.
With the NEC Express5800/ft series, 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 the ftsmaint command. After a new module is installed to
the server, enable the module using the ftsmaint command.
TIPS:
The system is defaulted to automatically boot the module, once installed. For more
information, see Chapter 5.
Make sure to provide the same hardware configuration on both CPU/IO modules.
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 ftsmaint.
