Proliant DL380 G4 not boot

[Zarathustra]

Server Proliant DL380 G4 has not booted after the next turn off. It switches on, starts to be initialized. All LED's shine the green. LED's "STATUS" change an order - but it is not described anywhere that they designate. On the screen it is displayed nothing. The description of these LED's would help, I think, to understand at what stage of initialization it rises and to understand, what to do further.
State LED's after which loading is enclosed does not proceed.
iLO it is not accessible (does not receive the address from DHCP)
