Always connect the server and the attached peripherals to the same power circuit. Otherwise you run the risk of losing data if, for example, the server is still running but a peripheral device (e.g. memory subsystem) fails during a power outage. Data cables must be adequately shielded. 32 Upgrade and Maintenance Manual CX400 S2

Important information Ethernet cabling has to comply with EN 50173 and EN 50174-1/2 standards or ISO/IEC 11801 standard respectively. The minimum requirement is a Category 5 shielded cable for 10/100 Ethernet, or a Category 5e cable for Gigabit Ethernet. Route the cables in such a way that they do not create a potential hazard (make sure no-one can trip over them) and that they cannot be damaged. When connecting the server, refer to the relevant instructions in this manual. Never connect or disconnect data transmission lines during a storm (risk of lightning hazard). Make sure that no objects (e.g. jewelry, paperclips etc.) or liquids can get inside the server (risk of electric shock, short circuit). In emergencies (e.g. damaged casing, controls or cables, penetration of liquids or foreign bodies), contact the system administrator or your customer service team. Only disconnect the system from the mains power supply if there is no risk of harming yourself. Proper operation of the system (in accordance with IEC 60950-1 resp. EN 60950-1) is only ensured if the casing is completely assembled and the rear covers for the installation slots have been fitted (electric shock, cooling, fire protection, interference suppression). Only install system expansions that satisfy the requirements and rules governing safety and electromagnetic compatibility and those relating to telecommunication terminals. If you install other expansions, they may damage the system or violate the safety regulations. Information on which system expansions are approved for installation can be obtained from our customer service center or your sales outlet. The components marked with a warning notice (e.g. lightning symbol) may only be opened, removed or exchanged by authorized, qualified personnel. Exception: CSS components can be replaced. The warranty is void if the server is damaged during installation or replacement of system expansions. Only set screen resolutions and refresh rates that are specified in the operating manual for the monitor. Otherwise, you may damage your monitor. If you are in any doubt, contact your sales outlet or customer service center. Before installing/removing internal options to/from the server, turn off the server, all peripheral devices, and any other connected devices. Also unplug all power cords from the outlet. Failure to do so can cause electric shock. CX400 S2 Upgrade and Maintenance Manual 33

Important information Do not damage or modify internal cables or devices. Doing so may cause a device failure, fire, or electric shock and will void the warranty and exempt the manufacturer from all liability. Devices inside the server remain hot after shutdown. Wait for a while after shutdown before installing or removing internal options. The circuit boards and soldered parts of internal options are exposed and can be damaged by static electricity. To ensure reliable protection, if you are wearing an earthing band on your wrist when working with this type of module, connect it to an unpainted, non-conducting metal part of the system. Do not touch the circuitry on boards or soldered parts. Hold the metallic areas or the edges of the circuit boards. Install the screw removed during installation/detaching internal options in former device/position. To use a screw of the different kind can cause a breakdown of equipment.

Basic software procedures 5.2.2 Performing a RAID array rebuild After replacing a hard disk drive that has been combined into a RAID array, RAID rebuild will be performed completely unattended as a background process. Figure 43: Progress bar (RAID array rebuild) V CAUTION! The system is now operational, however, data redundancy will not be available until the RAID array rebuild is complete. Depending on the hard disk drive capacity the overall process can take up to several hours, in some cases even days. I You may notice a slight performance impact during rebuild. 5.2.3 Using the Chassis ID Prom Tool System information like server name and model, housing type, serial number and manufacturing data are stored in the PDB or HDD backplane. In order to integrate your system into the ServerView management environment and to enable server installation using the ServerView Installation Manager, system data needs to be complete and correct. After replacing the PDB or HDD backplane, system information has to be entered using the ChassisId_Prom Tool. The tool and further instructions are available to maintenance personnel from the Fujitsu Technology Solutions Extranet: http://partners.ts.fujitsu.com/com/service/intelservers/tools I For the Japanese market, follow the instructions provided separately. 78 Upgrade and Maintenance Manual CX400 S2

6 Power supply Safety notes V CAUTION! Do not disassemble the power supply unit. Doing so may cause electric shock. Areas around the power supply unit may remain extremely hot after shutdown. After shutting down the server, wait for hot components to cool down before removing the power supply unit. When installing the power supply unit, be sure to confirm that the connector of the power supply unit is not damaged or bent. Do not insert your hands in the power supply unit slot when removing the power supply unit. Doing so may cause electric shock. If the power supply unit is hard to remove, do not pull out it by force. The power supply unit is heavy, so handle it carefully. If you drop it by mistake, injuries may result. Follow the safety instructions in the chapter "Important information" on page 31. 6.1 Basic information The server enclosure uses a hot-plug PSU, which automatically sets itself to a mains voltage in the range of 200-240 V. (For the Japanese market there are two PSUs available: PSU for 100V is set to a mains voltage in the range of 100V - 240V). As an option, the power supply can be expanded with an extra PSU to create a redundant power supply. If a PSU fails, the redundant configuration assures continued operation. The defective PSU can be replaced during operation. Complete PSU redundancy will work only in one-node configuration. In a multi-node configuration, full redundancy cannot be guaranteed. In case of PSU failure a warning is generated and all CPUs will be forced to work with the lowest frequency. CX400 S2 Upgrade and Maintenance Manual 79

Power supply Some configurations need two PSUs for normal operation. In this configurations a redundancy is not possible even if two PSUs are built-in. In this configurations, if one PSU failed, system can continue to work. but it goes to a throttling mode and it affects performance until replacement of the PSU. 6.1.1 General equipping rules Figure 44: Population rules for the power supply modules 1 Power supply module bay 1 (top) 2 Power supply module bay 2 (bottom) Both power supply modules must be of the same type. 6.2 Installing the power supply module Customer Replaceable Units (CRU) 80 Upgrade and Maintenance Manual CX400 S2

7 Hard disk drives / solid state drives Safety notes V CAUTION! The hard disk drive must not be removed from the installation frame by anyone except a service technician. HDD / SSD modules must all be marked clearly so that they can be reinstalled into their original mounting locations after an upgrade. Otherwise, data may be lost. Do not touch the circuitry on boards or soldered parts. Hold the metallic areas or the edges of the circuit boards. Before removing a hard disk drive, wait for about 30 seconds until the disk has stopped spinning completely. When a hard disk drive is starting up, a resonant noise may be audible for a short while. This does not indicate a failure. Depending on the OS, you can configure the write cache settings for the hard disk drives. If a power failure should occur while the write cache is enabled, cached data may be lost. When disposing of, transferring, or returning a hard disk or solid state drive, wipe out the data on the drive for your own security. Rough handling of hard disk drives may damage the stored data. To cope with any unexpected problems, always back up important data. When backing up data to another hard disk drive, you should make backups on a file or partition basis. Be careful not to hit the hard disk drive or bring it into contact with metallic objects. Handle the device on a shock and vibration free surface. Do not use the device in extremely hot or cold locations, or locations with extreme temperature changes. Never attempt to disassemble a hard disk or solid state drive. For further safety information, please refer to chapter "Important information" on page 31. CX400 S2 Upgrade and Maintenance Manual 99

Hard disk drives / solid state drives 7.1 Basic information Hard disk drives The server enclosure can be equipped with a maximum of 24 x 2.5-inch HDD/SSDs or 12 x 3.5-inch HDD modules. Each HDD module can accommodate an SAS/SATA hard disk drive or SSD drive with a maximum height of 1 inch. The module is connected to the SAS/SATA backplane wirelessly. This allows HDD/SSD modules to be plugged in or pulled out easily. Six SAS/SATA hard disk drives can be controlled by the onboard SAS/SATA controller. To control further SAS/SATA hard disk drives, an additional RAID controller must be installed. Hybrid configurations of SAS HDDs, SATA HDDs and SSDs within the same logical drive (RAID array) are not supported. If the server enclosure has the corresponding RAID configuration, HDD modules can also be replaced during operation. 7.1.1 General equipping rules Solid state drives (SSDs) are always equipped before installing hard disk drives. Hard disk drives / solid state drives with different capacities are installed from highest to lowest capacity. Hard disk drives with different rotation speeds are installed from highest to lowest speed. When installing hard disk drives with different bus technologies (SAS or SATA), first install SAS drives and then SATA drives.
