iLO Security Override Switch

The iLO Security Override Switch allows emergency access to the administrator with physical control over the server system board. Setting the iLO Security Override Switch allows login access, with all privileges, without a user ID and password.

The iLO Security Override Switch is located inside the server and cannot be accessed without opening the server enclosure. To set the iLO Security Override Switch, the server must be powered off and disconnected from the power source. Set the switch and then power on the server. Reverse the procedure to clear the iLO Security Override Switch.

A warning message is displayed on the iLO Web pages, indicating that the iLO Security Override Switch is currently in use. An iLO log entry is added recording the use of the iLO Security Override Switch. An SNMP alert may also be sent upon setting or clearing the iLO Security Override Switch.

In the unlikely event that it is necessary, setting the iLO Security Override Switch also enables you to flash the iLO boot block. The boot block is exposed until iLO is reset. HP recommends that you disconnect iLO from the network until the reset is complete.

Depending on the server, the iLO Security Override Switch may be a single jumper or it may be a specific switch position on a dip switch panel. To access the iLO Security Override Switch, refer to the server documentation.

Authentication Code Error Message

Within a Netscape or Mozilla browser, you might receive an incorrect message authentication code error message, which indicates that the public or private keypair and certificate used to initiate the browser's SSL session has changed. This error message can occur when you do not use a customer provided certificate, because iLO generates its own self-signed certificate each time it is rebooted.

To resolve this issue, close and restart the Web browser, or install your own certificates into iLO.
