HP StoreEver ESL G3 Tape Libraries - Manual (Page 28)

Drives must be installed in bottom-to-top order in the control module before any are added to the first
expansion module. There are two six-drive clusters in each of the first eight modules.
NOTE:
The term drive cluster defines a grouping of up to six tape drives below or above the middle X-axis
rail.
Figure 7 shows the locations of drives in the control module.

All LTO cartridges are the same size, which means they use the same magazines in the library.
LTO drives can be directly attached to hosts or attached to the SAN.
Operator Panel
The operator panel is located on the front of the control module and consists of the indicator panel
and the OCP (see
Figure 9 ). In the indicator panel, the buttons are for robot control and power, and
the indicators provide library status.
