Investigating S/N above 128. Take board#99, change to 0xe3 (227). Won't power up properly in crate 2. Move to crate 1 slot 2. Looks good according to scanCrate.pl:

2: MMC: 2.2 IP: 192.168.2.56 192.168.2.57 vv: 0x1002 sv: 0x0021 sn: 227

So IP last octet is 255-2*(sn & 127) and 254-2*(sn & 127). This is OK except that we should probably avoid IP address 128 as it would result in last octet = 255/254.

MAC addresses set as follows

Nmap scan report for rfc1918.address.not.used.bu.edu (192.168.2.56)
Host is up (0.000064s latency).
MAC Address: 08:00:30:F3:01:9C (Network Research)
Nmap scan report for rfc1918.address.not.used.bu.edu (192.168.2.57)
Host is up (0.000074s latency).
MAC Address: 08:00:30:F3:00:5C (Network Research)

The documented scheme is:

  bits 0-5     complement of serial number bits 0-5
  bit 6        =0 for T2 board (lower IP)
               =1 for T1 board (upper IP)
  bit 7, 8     serial number bits 6, 7 (not complemented for S/N < 64 only)

I'm confused.

Possible FEROL installation. What about this adapter?
