• When five ports (SW800) or two ports (SW500) have doubled shelves for
5¼-inch SBBs (4+2), TZ8x7 tapes cannot be connected or even mounted in the
cabinet because all or most (front) shelf locations are needed for the 5¼-inch
SBBs.

Key for Table Conventions
Each BA350–SB shelf has its upper connector cable attached to either the adjacent BA350–SB
shelf’s lower connector (1x6J), or a controller port connector (2x3T or 1x6T).
The lower connector cable is attached to either an adjacent BA350–SB shelf’s upper connector
(1x6J, as in the first list item), controller port connector (2x3T), or is unused (1x6T).
Parentheses () around a number indicate the number of storage shelves.
T indicates the shelf is terminated.
J indicates the shelf is not terminated and jumpered to the next shelf.
* Consult the StorageWorks Solutions Shelf and SBB User’s Guide to configure BA350–SB storage
shelves.
** Available for additional 5¼-inch device.
*** When used with the controller in the C1 position in an SW800-series or SW500-series cabinet.
(Refer to Figure 3–1 for SW800-series data center cabinet controller positions.)
