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.
