controller unit E310fD (fibre channel, dual controllers)
JBOD unit J310sD (dual controllers)
1 controller unit can have up to 4 JBOD units attached to it.

WebPAM default IP address: 10.0.0.1
default credentials: administrator, password

also the rails on these things are terrible. the only plausible way to mount them is to take all the drives and other removable components out of the array and then have at least 2 people help guide the unit into the rail guides.
