Issue 02 (2015-09-22)
Connect two Fibre Channel ports on each CNEN respectively to any 8 Gbit/s Fibre Channel
port separately on SUCs A and B.
1. Connect two Fibre Channel ports on each CNEN respectively to two Fibre Channel
switches.
2. Connect two Fibre Channel ports on each SUC's controller A and on each SUC's
controller B respectively to two Fibre Channel switches.
NOTE
For details on how to route and bind cables, see
Cable Routing and Bundling
Mini SAS cables (applicable to the SUD with SAS expansion ports)
Optical fibers, optical bundling tape, 4 Gbit/s optical transceivers (applicable to the SUD
with Fibre Channel expansion ports)
Cable ties
Diagonal pliers
For the loop in which the configuration disk enclosure (namely, the SUD housing coffer
disks) reside, obtain one 4 Gbit/s optical transceivers separately from the second SUD and
the last SUD (the configuration disk enclosure is considered as the first disk enclosure, and
other disk enclosures above the configuration disk enclosure are numbered from the bottom
up).
For other loops, obtain one 4 Gbit/s optical transceivers separately from the first SUD and
the last SUD (numbered from the bottom up).
All EXP ports can connect only to PRI ports.
