If iLO is unavailable from power-on through operating system boot and a local keyboard is not present, Remote Console keyboard functionality might not function when iLO becomes available again, depending on the operating system. iLO can become unavailable for various reasons, including firmware upgrade, network settings change, or reassignment of ports. It might be necessary to power cycle the system to regain Remote Console keyboard functionality.

If iLO is unavailable from power-on through operating system boot and a local keyboard is hot-plugged after operating system boot, the Remote Console and local keyboard might not function when iLO becomes available again, depending on the operating system. iLO can become unavailable for various reasons, including a firmware upgrade, network settings change, or reassignment of ports. It might be necessary to power cycle the system to regain Remote Console and local keyboard functionality.

If iLO should become so busy that it is unable to respond in a timely fashion to keyboard commands sent by operating system while the operating system is loading and a local keyboard is not present, the operating system will assume that no keyboard is connected. This situation is unlikely but can theoretically occur any time iLO becomes extremely busy. An example of this condition is when iLO experiences a Denial of Service attack over its NIC. In this case, if a keyboard is hot-plugged after the operating system is loaded, local and Remote Console keyboard functionality might not function, depending on the operating system. It might be necessary to power cycle the system to regain Remote Console keyboard functionality.

If a local keyboard is hot-unplugged after the operating system boots with caps-lock, num-lock, or scroll lock on and then is hot-plugged, the LED indicators on the local keyboard will not reflect the current state of the keyboard. Press the lock key for the desired function until the correct LED indicator state is reached.

If the local keyboard locks up when hot-plugged, unplug the keyboard and plug it in again.
