Per the sticker the comes on the front of the chassis:

While the FC ports come up fairly fast, the Ethernet interface takes a bit longer (several minutes?).  I have 6 of these units and they all came with the same defaults.  All of the units are currently running firmware v5.0.10.0 but some of them came out of the box with an earlier version.  This should apply to SKUs SB1404-10AJ-E and SB1404-10AS.
