TOPIC


    This article describes the most common reasons why a Network Server 500 or 700 will not power on.

DISCUSSION


    The assumptions made in this article are:
    * the power cord is good
    * the interlock switch in the rear is closed
    * the server has a power source


    Listed below are common reasons for a failure to power up, followed by notes and explanation:

    1) Toggle bolts on the rear of the logic board not fully tightened.
    2) Server frame slightly bent causing micro switch in rear of server to
    not make contact.
    3) CPU card (or any other devices in the PCI slots) not fully seated.
    4) Logic Board interconnect not making full connection.
    5) Logic board defective.
    6) Power supply defective. (Note: The Network Server 700 has two power
    supplies.)
    7) Interlock switch in rear defective.
    8) Key Switch in front defective.
    9) Defective on/off switch.

    Notes
    -----
    The first 6 items in the list above are listed in order of probable cause; items 7, 8, and 9 are not.

    When facing the rear of the network server, the micro switch is located near the lower left edge of the logic board face plate. There is a plastic protrusion which inserts into a slot in the chassis. The Micro switch can be seen if you look through the grill.
