In the unlikely event that it is necessary, enabling the iLO Security Override also
enables the iLO BootBlock to be flashed. The BootBlock will be exposed until the
iLO is reset. HP recommends disconnecting the iLO from the network until the reset
is complete.
To reset the iLO Security Override Switch:
1. If the server is on, place it in Standby mode. Refer to Chapter 7 for instructions.
2. Open the top access panels to gain access to the host module. Refer to Chapter 3
for instructions.
3. Locate switchbank 7 (SW7) on the system board. Set switch 8 to the enabled
position.
4. Replace the server access panel.
5. Press the Power/On Standby switch to power on the server and resume normal
operation.
