Use This Table To Identify The File Module; Port Locations - IBM Storwize V7000 Unified Quick Installation Manual

v No more than five expansion enclosures can be chained to port 1 (below the
control enclosure). The connecting sequence from port 1 of the node canister is
called chain 1.
v No more than four expansion enclosures can be chained to port 2 (above the
control enclosure). The connecting sequence from port 2 of the node canister is
called chain 2.
v No cable can be connected between a port on an upper canister and a port on a
lower canister.
v Attach cables serially between enclosures; do not skip an enclosure.
v The last enclosure in a chain must not have cables in port 2 of canister 1 and
port 2 of canister 2.
v Ensure that cables are installed in a tidy manner to reduce the risk of cable
damage when Storwize V7000 Unified replaceable units are removed or inserted.
v Arrange your cables to provide access to:
– The USB ports. Access is required to this port when you use the USB flash
drive to configure the system.
– The enclosures themselves. Access is required to the hardware for servicing
and for safely removing and replacing components using two or more people.
v Ensure that each SAS cable is fully inserted. A click is heard when the cable is
successfully inserted.
Note: If you make a mistake during cabling and must unplug a SAS cable, pull
the blue tag to release the cable.
