Bypassing an unknown power-on password When a power-on password is set, POST does not complete until you enter the password. If you forget the power-on password, you can regain access to the server through either of the following methods: Enter the administrator password at the power-on prompt, if an administrator password has been set. (If necessary, see "Using the Administrator Password menu" on page 28 for details.) Start the Configuration/Setup Utility program and change the power-on password. See "Using the power-on password menu" on page 26. Change the position of the jumper on J24 as described in Table 18 on page 280 to bypass the power-on password check. You can then start the Configuration/Setup Utility program and change the power-on password. See "Using the power-on password menu" on page 26. Ethernet subsystem error messages Notes 1. The following error messages may be displayed if "Network" is selected in the startup sequence of the configuration program. 2. The following error messages are available only with the integrated Ethernet subsystem. These error messages are not available when RPL (remote program load) or DHCP (dynamic host configuration protocol) is used through optional network adapters. RPL-related error messages: If a failure condition occurs after the Ethernet controller is initialized, an error message appears on the screen. The two most common error messages are: RPL-ROM-ERR: 1 5 The integrated Ethernet failed the loopback test. RPL-ROM-ERR: 1 7 Media test failed; check the cable. Error 105 indicates that a power-on diagnostic test performed by the Ethernet module did not execute correctly. Error 107 indicates that the cable from the LAN is not securely connected to the Ethernet port on the computer. Check the cable to ensure that it is properly connected. The following list contains other error codes that might occur, followed by a description of the error code. Netfinity 5500 M20 - Type 8662 45
