Chapter 2 Preparations
1. If the server is mounted on a rack, use the UID switch to identify the target server as needed.
See Chapter 2 (1.5 Confirming Servers (UID Switch)).
2. Set to the maintenance mode. See Chapter 3 (7.7.1 BMC – (7) Extended Functionality) for details.
3. Remove the Front Bezel, if installed.
See Chapter 2 (1.6 Removing Front Bezel).
4. If the server is ON, turn it off. Press the BMC shutdown switch on front panel. After making sure that
MGB#1 Status LED on rear panel is unlit, disconnect power cable from the server, and from outlet. See
Chapter 3 (13. Turning Off the Server) for powering off the server.
You can install or remove CRU (hard disk drive / power supply unit / cooling fan) while the server is
powered on.
5. Depending on the components to be installed or removed, follow the procedure in order.
See Chapter 2 (1.7 Optical Disk Drive) to (1.18 SUV Cable).
6. Install the removed components to original place in the server.
Install the components/cables which are removed while removing or adding the other part/cable to the
original place in the server accurately. Missing any components/cables or installing the
components/cable incompletely may result in some malfunction.
For how to mount front bezel, see Chapter 2 (1.17 Installing the Front Bezel).
7. Ensure not to leave any components or screws inside the server.
If the DC power is turned on while a conductive part such as screw is left on the motherboard or the
terminal of cable in the server, some malfunction or failure may occur.
8. Check if any cables do not prevent the air flow from cooling the system
If any cables are installed improperly and prevent the air flow, it reduces the cooling effect in the server,
resulting in some malfunction.
9. Confirm that the replacement/installation is done properly using tools.
Using tools such as System Diagnostic Utility or BIOS Setup Utility, confirm that the component/device is
replaced/installed properly. Refer to the replacing/installing procedure of each component/device for
detail
10. Turn off the SYSTEM STATUS LED.
If CRU is installed/removed while the system power is on (online), the SYSTEM STATUS LED may stay
lit amber. In this case, perform Clear All Faults to turn off the SYSTEM STATUS LED.
Important Perform Clear All Faults after all the failed components are replaced. If any of failed
component is left, proceed to next replacement process. You can check if any
component is left as failed by viewing NEXT LED. (See Chapter 1 (5.6.5 FRU (NEXT,
PROC, MEM, PCI, PSU/FAN, MISC) LED). If NEXT LED is lit amber, it indicates some
failed component is left and is not replaced. If you need to perform Clear All Faults,
write down information about the failed component (e.g., component type and
installed location, and others) before executing the command. See Chapter 3 (7.9.2
Component Status Fault Information) for how to perform Clear All Faults.
Important If any of HDDs is defective, the SYSTEM STATUS LED, Disk Access LEC, and HDD
LED for each HDD will be lit amber. If the HDD is replaced in the DC power off status,
Disk Access LED and HDD LED for each HDD turn off automatically. Perform Clear
All Faults to turn off the SYSTEM STATUS LED. If the HDD is replaced in the DC
power on status, Disk Access LED and HDD LED for each HDD stay lit amber.
Perform Clear All Faults to turn off the SYSTEM STATUS LED. When the system is
rebooted and POST is completed, Disk Access LED and HDD LED for each HDD will
turn off automatically.
