enclosure ID and slot number as illustrated.
The InfiniteStorage 6120 supports mixing SAS and SATA drives within the same enclosure. For
most efficient airflow and reduced vibrations, SAS drives should be placed in the front of the
enclosure (lower slot numbers) while SATA drives should be placed in the rear of the enclosure
(higher slot numbers).

Initial Configuration via RS-232

The InfiniteStorage 6120 can be configured and administered either via serial connection (using the
supplied mini-jack cable) or via Ethernet connection using SSH. However, in order to use the SSH
connection, it is first necessary to configure the network settings on each controller. This can only
be done using the serial interface as described in the next subsection.
