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.
