For x1dc0, removed the 3 slot PCIe riser card, installed a 4 slot PCIe riser.  Installed 3 10GE fiber cards, 1 IRIG-B card.  2 of the 10GE cards are configured for mx communication to the x1daq switch to allow testing of daqd software on multiple paths.  The x1daq switch is configured for 1 vlan for both 10GE fibers and all the front end computers.  Through experimentation, the following order of cards has been determined:

(top to bottom)

10GE mx :0
10GE eth2
10GE mx :1
IRIG-B

Also restarted x1nds0, wouldn't allow ssh login.
