Powering Up the HPAA System
There are up to eight components that need to be powered on in

• Console Switch Box
• Monitor
Before examining the power on sequence, first take a look at a
typical rack implementation and how it is cabled from the
perspectives of AA 4000 hardware, the console switch, and power.
Cabling the AA 4000 hardware
Once the peripherals have been added to the NetServers and all of
the components are rack mounted, including the SSDLs, then the
external cabling for the array can be completed.
The above diagram is an overall view of the cables directly related to
the array’s availability. One cable is used for the IOP Link; this is an
UTP CAT-5 patch cable. The rest of the cables are the 100-pin
ribbon cable that interconnects the tuples through the SSDLs.
CAUTION
Place the tuple cables in their respective connectors and
make a firm connection. Once the connection is made
correctly, then tighten the screw about half a turn. Do not
