Hello extenue,
I've currently two Proliant, one N54L and one N40L. The N40L is running the 6.2.2-24922 Update 4, and the N54L is still running 6.1.7, but will be upgraded very soon.
To run the 6.2 version you need to add a new network card as the internal NIC is no longer supported.
I've added a HP NC360T card.
Regards,
TomX
