Recovery booting a QNAP TS-419PII

While following the instructions of the recovery boot at the debian qnap pages I had the problem that the system would not load the provided image via TFTP. In tcpdump you could see that the system requested a slightly different file via DHCP:

12:47:44.935498 IP (tos 0x0, ttl 255, id 1, offset 0, flags [DF], proto UDP (17), length 329)
    10.7.7.21.68 > 255.255.255.255.67: [no cksum] BOOTP/DHCP, Request from 00:08:9b:cd:26:04, length 301, xid 0x9bcd5771, secs 12, Flags [none] (0x0000)
          Your-IP 10.7.7.21
          Server-IP 10.7.7.253
          Client-Ethernet-Address 00:08:9b:cd:26:04
          Vendor-rfc1048 Extensions
            Magic Cookie 0x63825363
            DHCP-Message Option 53, length 1: Request
            MSZ Option 57, length 2: 576
            Server-ID Option 54, length 4: 10.7.7.253
            Requested-IP Option 50, length 4: 10.7.7.21
            Vendor-Class Option 60, length 11: "F_TS-419P2+"
            Parameter-Request Option 55, length 5: 
              Subnet-Mask, Default-Gateway, Hostname, BS
              RP

While the instrunction lists the filename for these machines as "F_TS-419P2", this (newer?) revision requests "F_TS-419P2+".
