Data domain - megarac service processor problem - how to reboot IPMI card

I have DD2500 5.4.0.7  IPMI interface configured.

connection to ipmi card is available through ipmi over ssl and ssh, but when i try www i get "Unable to connect".

There is www service but now unavailable.

i need to reboot/reset ipmi card, but without rebooting whole DD.

could you give me any help, command, manual. Until now i found nothing.

even support answers that www is not supported, maybe but useful.

all the best tomasz
