1.2 Storage Expansion Subsystem
In addition to the CoolShell CS-3U and its 3RU subrack, Themis has introduced a
Storage Expansion Subsystem (see Figure 1-6 )—used to provide increased stor-
age—and installed within the same 19” rack above the 3RU subrack. [The installer
may locate the Subsystem below the 3RU subrack if necessary.]
Installation procedures for connecting the CoolShell CS-3U to the Storage Expan-
sion Subsystem are given in Chapter 2, "Installation and Operation".
