A new TS7760 Storage Expansion Frame can be added to a TS7760 Base Frame fully configured with a
3956-CSA cache controller and nine
3956-XSA cache drawers by using
FC 7334, TS7760 Encryption Capable Expansion Frame (VEC section below) as a
miscellaneous equipment specification (MES).
Note: A TS7700 Base Frame that contains 3956-CS8 or 3956-CS9 cache controllers but is not fully
configured can add a TS7760 Storage Expansion Frame containing a 3956-CSA cache controller and up to 15
3956-XSA cache drawers.
Refer
to the topic Upgrades specific to the TS7760 in the Related
