1.6 Other Precautions
Caution - Observe the precautions shown below to ensure the safety of the system.
  1. The printed circuit boards in the SPARC M12-2/M12-2S can be easily damaged by static electricity. To prevent damage to the printed circuit boards, wear a wrist strap, and connect it to the chassis prior to starting maintenance.
  2. When mounting any unit in the SPARC M12-2/M12-2S, check the connectors beforehand to confirm that none of the pins are bent and that all the pins are neatly arranged in lines. If a unit is mounted with a bent pin in a connector, the SPARC M12-2/M12-2S may be damaged. When mounting a component, perform the work carefully so as not to bend any pins.
  3. If excessive force is applied to a CPU memory unit, the units mounted on printed circuit boards may be damaged. When handling a CPU memory unit, observe the following precautions.
    - Hold the CPU memory unit by the metal frame.

    - When holding the CPU memory unit, keep it horizontal until you lay it on the cushioned ESD mat.

    - The CPU memory unit consists of printed circuit boards connected with thin connection pins. Therefore, do not place the CPU memory unit on a hard surface.

    - Be careful not to damage the components located on either side of the CPU memory unit.
  4. The heat sinks can be damaged by incorrect handling. Do not touch the heat sinks while replacing or removing a CPU memory unit. If a heat sink is disconnected or otherwise damaged, obtain a replacement CPU memory unit. When storing or carrying a CPU memory unit, ensure that the heat sinks are sufficiently protected.
  5. When removing a cable such as a LAN cable, if you cannot reach the latch lock of the connector, use a flathead screwdriver, etc. to push the latch and release the cable. If you use force to remove the cable, the LAN port of the CPU memory unit or the PCI Express card may be damaged.
  6. Do not use any power cords other than those specified.
  7. Check the appearance of the products before starting work. When unpacking them, confirm that no unit is deformed, no connector is damaged, and there are no other such defects.
    Do not mount the products that have a defect in the appearance. Mounting a product that has a defect in appearance may damage the SPARC M12-2/M12-2S.
