Well - the iLO is a seperate subsystem, so if the system has a 
motherboard failure then the iLO will tell you that prior to initiating 
any console.  And if the motherboard is failed, then there was little 
point looking at the console in the first place, as the system won't 
boot. The iLO port is a seperate network port on a different system, so 
it is independent of any network problem you might have.
I'm not necessarily talking about using the iLO remotely, although it 
can and is usually used that way, so if you have some internet 
connectivity problem your engineer can still connect to the port with a 
network cable and get POST status and connect to the console if 
necessary on his laptop.
I wasn't asking that you replace your existing servers, just mentioning 
that integrated remote management ought to be a serious consideration 
when you're going for unmanned systems.
The USB kit mentioned earlier in this thread may be a viable solution 
for what you're looking for - you'll need one for each engineer though, 
and only you will know the numbers (# of servers, # of engineers, 
overall cost) which will define the best solution for you.
