NOTE If you have drive trays with inverted ESM canisters, see
Arrangements" on page 69.
If you are connecting one CDE3994 controller-drive tray to six drive trays, and those
drive trays have inverted ESM canisters, use the cabling topology shown in the
following table and figure.
NOTE The CDE3994 controller-drive tray supports a maximum of seven drive trays.
However, if you are using the FC4600 drive tray in your configuration, plan for a limit
of six FC4600 drive trays. Seven FC4600 drive trays fully populated with drives
exceed the maximum number of drives supported on a single drive channel.
