Link Controller Card
Act like FC hubs with the chassis backplanelinking FC_AL devices together
Links DAEs to DPEs allowing disk/loopexpansion
The LCC passes the input signal to the diskdrives in the enclosure; it then sends the
output signal, via cables, to the next DAE inthe loop.
Independently monitors the environmentalstatus of the entire enclosure.
controls the LCC port bypass circuits and thedisk-module status lights.
LCCs do not communicate with, or controleach other.

Powering on
Safely powering on the Array
Power on DAEs first [allow 1 min] Power on DPE/SPE from SPS
Safely powering off the Array
Power down the DPE/SPE from the SPS ONLY![this allows cache to flush cleanly, usually takes 2 mins ]
