Caution: Be sure to install the SAS cables correctly before you turn on the expansion
shelf. If you need to disconnect and reconnect cables on an operational expansion
shelf, there is a risk that the primary shelf cannot recognize the new configuration.
Prerequisites for adding an expansion shelf
Be sure that you have 4U of rack space for each new shelf. One shelf must be
■

Refer to the following section to verify that cable lengths are adequate for your
■
