On my system:
[root@odin ~]# pasu r2 show IMM|grep -i telnet
r2: IMM.TelnetPort=23
r2: IMM.TelnetLegacyPortControl=Open
r2: IMM.TelnetSessions=2
By the way, is there something specific you want out of telnet versus another
protocol? The same CLI is over ssh, and we strongly recommend using that,
since it is open by default.

I don't think that went through:

you can try to "reset" the BMC:
ipmitool mc reset warm (or "cold" if a warm reset is not enough).
Or maybe the raw command changed since there are new servers (and new
BMCs firmware I guess)?
On a Supermicro I had to run this from the OS to set the BMC to shared:
ipmitool raw 0x30 0x70 0x0c 1 1
And to check the actual value:
ipmitool raw 0x30 0x70 0x0c 0
