NEC 320Lb-R manual Preparing Your System for Upgrade

Preparing Your System for Upgrade

Always observe the following guidelines when replacing or installing devices in your system.

!Your fault-tolerant server allows you to remove, install, and replace devices while the server is in continuous operation. However, when it is necessary to work on the server with its power off, you must use the Windows 2000 shut down procedures, power off the server, and disconnect all the power cords and interface cables.

!To remove a CPU module or PCI module while the system is in an operational state the module must be disabled (placed into off-line status) by using the server utility of the ESMPRO/ServerAgent or the ESMPRO/ServerManager from the management PC on the network. Then after a new module is installed it must be reenabled by using the server utility of the ESMPRO/ServerAgent or the ESMPRO/ServerManager.

Note: The system default automatically boots a module, once installed.

!Do not remove a CRU when its amber status LED indicator is on. This indicates that the CRU is operating in simplex mode (i.e., its duplex partner is not functional) and removing it will cause the system to fail.

!Provide the same hardware configuration for both group 1 and group 2.

!Ensure that the installed devices have the same specifications, performance, and features.

Have the following tools available:

!Phillips screwdriver (#2 bit)

!flat-head screwdriver

!small needle nose pliers

!pen or pencil

!utility knife

!ESD workstation or antistatic wrist strap (recommended.)
