What is HP Proliant Integrated Lights-out port ? How to configure and make use of it ?

Many thanks.

HP Proliant Integrated Lights-out port is a dedicated "NIC" with it's own logic. It can be configured in order to have an IP Address and be connected to the network (same or different VLAN as servers) in order to remotely control the server like you could do through RDP and the ordinary NIC of the server.

Better than RDP because iLO allows you to control the server with enhanced features: control during server's bootstrap (and untill OS GUI comes up), wake up server, mapping server side your local resources (FD, CD ecc), SSL control and generally control the server at low level like if you where in front of it.

The full iLO license allows you to control server even with OS up, so you have full control but is an add on you must pay for it.

For the configuration of the specific HP model you have you must connect to HP website and find the relative documentation for your server model/generation.
What I consider the biggest and best feature of ILO is the abiliity to reboot a server remotely if it has bluescreened or froze and to start if it has been shut down. the virtual power button has been a life saver.
as a basic overview, the ILO port allows you to have a second IP address on the network for the server which provides a built in web based interface even if the server is turned off (as long as it has power)
It can provide remote control facilities, access to the power buttons etc. Its great!
An iLO is an Integrated Lights Out card that can be found on HP servers.  Nowadays, these cards are integrated on the motherboards of the new servers, however, you used to be able to get PCI iLO cards that you could add to any server that did not have an embedded iLO - not entirely sure if these are available still.

The iLO is completely independant of ay OS running on the server and so can be accessed even before you install an OS on the server.

There are a few HP servers that also have a shared iLO / NIC port instead of a dedicated iLO port.  To utilise the iLO on these servers, the IP address allocated to the iLO needs to be in the same subnet / VLAN as the IP address that you have allocated (or are going to allocate) to the OS.  

The iLO enables you to manage the server remotely even when the server OS is shutdown (providing that a live power cable is connected).

Some of its useful features are

Virtual Power:
This allows you to press the power button on the server remotely so you can power the server up or down and reset the server even when you are not on site.

Remote Console:
This allows you to view the server consle as though you were standing in front of the server, so you can see the entire boot sequence etc.  Infact, when you make mouse movements or provide key input via the Remote Console, anyone standing in front of the servers screen can actually see what you are doing

Virtual Media:
This allows you to tell the server to use an ISO image that is located on the network or to use your own CD drive in your PC as its CD drive.  This means that you can install an OS or any application without having to be in front of the server.

The iLO needs its own IP address allocated to it.   To access the setup for the iLO, you need to pres F8 during the boot sequence of the server.  Depending on your BIOS configuration, you may or may not be prompted to press F8 to enter the iLO Setup, in either case, pressing F8 at the right time will enter the iLO setup.  Once in the setup utility, you can specify an IP address, Subnet Mask, Defualt Gateway, iLO Name etc for the iLO, you can also grant access to the iLO to new user accounts, giving each a differing level of access for security purposes.  These user accounts are specified independanty and are not taken from AD or any other directory service.

Once you have configured the iLO correctly, you can access it through a web browser directly using its IP address (or DNS name if you have configured a DNS entry for it) - you will need to exit the iLO setup to save the configuration changes before you can access it via the web browser.  Most places I have worked usually set a DNS name of <servername>rib for the iLO card, this is because before the iLO was introduced, HP's offering of remote server management was know as the Remote Insight Board.

Hope this helps

Real simple question, once you have purchased the license from HP how do you activate it?  Is there documentation anywhere on how to work with it?
