shelves to an existing appliance installation.
Installing storage shelves to an appliance that
has at least one storage shelf
The installation of storage shelves in a rack to an appliance that already has at
least one storage shelf does not differ much from other installation scenarios. Refer
to the following sections for detailed instructions. Read all of the information before
starting.
See “Storage shelf rack requirements” on page 25.
See “Determining rack locations” on page 24.
See “Installing the storage shelf rack rails” on page 29.
See “Installing the storage shelf into a rack” on page 31.
See “Understanding appliance and storage shelf connections” on page 38.
To add up to four storage shelves to an appliance that has at least one storage
shelf, See
“Recabling to connect additional shelves” on page 135.
Recabling to connect additional shelves
When storage shelves are added to an appliance that already has at least one
storage shelf you need to reroute one existing cable connection. You also need to
install the new cables that ship with the additional storage shelf or shelves. Each
storage shelf ships with two 1-meter SAS-3 cables.
The following sections provide cable instructions for an appliance and a total of four
storage shelves. The instructions are the same for five or six storage shelves.
