Hi.
We bought an extension for our FAS 270c. It's a shelf of 14x300GB disks with ESH4 heads (don't know the name).
On my FAS 270c, head A is an host : "myuphost" and head B is another one : "mydownhost", each have some disks assigned. I want to assign all new disks to head A ("myuphost").
I don't know what to connect to what.
On my FAS270c :
Head A (up) : FC B : nothing
FC C : gbic with a LC loopback in
Head B (down) : FC B : nothing
FC C : gbic with a LC loopback in

(this picture is not mine because there are no LC loopback, but heads are the same)
On my Extension :
Head ESH4 A (up) : "IN" port and "OUT" port
Head ESH4 B (down) : "IN" port and "OUT" Port
Do I have to connect Head A FC port (C) to ESH4 A "OUT" and plug the loopback in ESH4 A "IN" ? (and also for Head B with ESH B ? )
Thanks a lot.
