BMC is not detected.

Hi all. I have a server PowerEdge R200  with bmc, but I can not connect to the bmc over lan. I set up a network through ipmitool.

ipmitool lan print 1

I can not ping, but he has in ARP table.

arp -a

I tried to connect to port 623 via netcat

nc -uv 192.168.162.75 623
Connection to 192.168.162.75 623 port [udp/asf-rmcp] succeeded!

When try to connect, I get an error

IPMISH>connect -ip 192.168.162.75 -u root -p admin
Error(0xae):BMC Error - BMC is not accessible.

Do you have any idea what would solve this problem?
