[INSTRM-92] CCD serial numbers on new FEE are junk

Wed, 6 Sep 2017 12:16:07 +0000

The CCD serial numbers on unconfigured FEEs look like junk memory:

pfs@pfsDevSvr:~$ oneCmd.py ccd_r7 fee status serial
2017-02-09T17:22:30.722 ccd_r7 i serial_fee="3060344"
2017-02-09T17:22:30.723 ccd_r7 i serial_adc="4294967295"
2017-02-09T17:22:30.726 ccd_r7 i serial_pa0="4294967295"
2017-02-09T17:22:30.727 ccd_r7 i serial_ccd0="ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ3N7ÃCCD0"
2017-02-09T17:22:30.729 ccd_r7 i serial_ccd1="ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ3N7"

We do set those early, but it would be less worrisome to have them be empty strings or "unknown".
