IPMI on 5230 running v.2.6.0.1 not working

I have a Netbackup Appliance 5230 running on v.2.6.0.1 and I've not previously configured .

I'm configuring the appliance for a POC and so it's not on a network at the moment. It's the same way I upgraded it to current version.

Have followed instructions on IPMI config, set the IP in BIOS. But I can't ping it, can't connect at all.

Some guidance needed please.
