17600 – System Data
System data consists of 28 bytes. The first two bytes have the current alarm contact
settings (big-endian). Each bit corresponds to a contact. Bit 0 (lsb) of byte 1 is the bit for
the Power Supply 1 alarm, and bit 7 (msb) is the bit for the 'any' alarm. The next five bytes
are for the installed card inventory. A '0' bit means the card is installed and a '1' bit means
the card is removed. The other bytes are for internal use.
17601:17620 – Card Data
Each I/O card in the VxRouter has an associated TCP port. Card 1 uses port 17601, card 2
uses 17602, and so on. The data is formatted as follows:
• 16 bytes, internal use
• 2 bytes, card type
◦
0xff, 0xff missing
◦ 0x00, 0x62 VX640 I/O card (bits 7-4, ignore bits 3-0)
• signed 16-bits, card temperature (little-endian, bits 15-7)
◦
example: 0x80 0x1d -> 0x1d80 -> 29.5°C
• 5 bytes, internal use
• SFP data, 256 bytes per SFP, 16 SFPs per card
◦
128 bytes, SFP ID data
◦ 128 bytes, SFP diagnostic data
