Unpack and inspect the NTAG54 Daughterboard.
Mount the NTAG54. The NTAG54 can be mounted on any DDP2
NT5D97AD. Slots that are occupied by BTU's prevent the insertion
of daughterboards.
The NTAG54 comes with 4 stand-offs so that it can be mounted
onto the Dual PRI. These are easily pushed into 4 corresponding
mounting holes on the Dual PRI.
The NTAG54 is mounted so that it mates correctly with P9 and
P11 on the Dual PRI motherboard.
