From hifi-remote.com, the Cisco ISB2201 uses the TDC-38 IR protocol device 6, subdevice 10.  Power is function 22:
0000 006D 0000 000D 000C 0018 000C 000C 0018 000C 000C 0018 000C 000C 0018 0018 0018 0018 000C 000C 000C 000C 0018 0018 0018 000C 000C 0018 000C 0D36
Maybe the 7150 uses the same IR protocol.
