Installation guide

A full SF2xx houses 24 RF disks (in six SF7x enclosure boxes) and two
TF857 tape loaders (see Figure 3–7). SF2xx cabinets can be ordered with
fewer disks and be upgraded in the field as the customer needs require.
The SF2xx has four levels: levels 1, 2, and 4 house RF disks in SF7x
enclosure boxes (two or four disks per SF7x). Level 3 is reserved for tapes
and can hold two TF857 tape loaders.
The number of buses needed to support a full SF2xx cabinet varies,
depending on how the SF7x enclosures are configured: split- or through-
bus.
