HowTo: detect and connect to Oracle / Sun Microsytems ILOMs (Integrated Lights Out Manager)


· A laptop PC (with windows)
· NetScan from Softperfect (it’s free for personal & professional use)
· An ethernet cable (ie: cat5-6, normal cable -no crossover needed-)


1.- If you haven’t done it already, go to Softperfects web and download the latest version of NetScanner.
Why I like this program? well, it’s free, it’s portable (I love portables BTW), it’s one of the best scanners that I have seen, and it’s free (did I say that already?).

2.- Conect your laptop to the “Net Mgmt” ethernet port of your server, and change your laptop’s local IP address to, with a gateway of

3.- Open NetScan, let it identify your NICs IP network, and start the scan.


4.- As soon as you have 2 entries displayed on NetScan, you can save time and pause the scan process.


5.- Select the last IP shown, and right click, open as Secure HTTP (HTTPS).


6.- Voilá, You may get a certificate error, ignore that, and you will be able to login;


a browser windows should have opened with the ILOM login’s page.

remember that the default user/password to access is root/changeme.

7.- Now you can do what you wanted to do in the ILOM, log off, and go for another server…



Oracle Hardware – How to replace a Blade from a Sun Blade 8000 chassis.

Today I will do a post with some nice photos of blades hardware ;o)

Well, on this post we’re going to describe the process of replacing a faulty blade, for a good one.


-To have the replacement blade, equal to the one that we are replacing, would be a good start.

To replace a Blade, we basically need to follow this steps:

1.- Power off blade,

2.- Remove the blade from the chassis, -the chassis without blade will look like this:

3.- Take off the blade’s cover,

4.- Remove and set aside the HDs of the blade (better leave them in top of an anti-static mat)

5.- Remove and set aside the RAM SIMMs of the blade (and leave them in the anti-static mat)

6.- Remove and set aside the CPUs Heat Dissipators of the blade (and leave them in the anti-static mat)

7.- Clean the CPUs and the Heat Dissipators of the heat conducting paste with a special cleaning cloth
(you can buy them on and IT shop, next to the heat conducting paste)

8.- Remove and set aside the CPUs of the blade (and leave them in the anti-static mat)

9.- Prepare the new blade, and take off it’s cover,

10.- Insert the CPUs from the old blade,

11.- Apply new heat conducting paste to each CPU (with the syringe: I usually put a big dot in the center, but if you really want to get into it, there are lots of pages on the internet about how to corrrectly apply heat dissipator paste to a CPU),

12.- Put the CPU Heat Dissipators (careful with the pressure applied to the screws, you don’t want one of this broken – in fact, I always screw them crossed like the car tires: if we have screws 1,2,3,4, I will half screw 1, 3, 2, 4, and then finish off 1,3,2,4 again, that ensures even pressure has been applied to the heat dissipator),

13.- Put the RAM DIMMs,

14.- Put the HDs,

15.- Put the cover, and reseat the blade on the chassis,

16.- Power On, and check the lights for green ( if an orange light appears, look at the ILOM, you may have a problem ;o(  )

The old blade will look all empty and sad on one side:

This instructions are from a Sun Blade 8000, but they are pretty simmilar for an IBM BladeCenter blade.

In any case, this procedure is usually performed by an Oracle Field Service Engineer (FSE), as a blade or motherboard is a Field Replaceable Unit (FRU), not a Customer Replaceable Unit (CRU); but it may be of use to those who have a blade at home, or to the inquisitive type sysadmins.

And that’s about the size of it,

thanks for reading.
