Introduction
Hitachi AMS 2000 Family Storage System Service Guide
AMS 2100/2300 base unit rear panel
This section describes the components on the rear panel of both the AMS
2100 and the AMS 2300. While most of the components on the rear panels
of the AMS 2100 and AMS 2300 are the same, some components in the base
units are different.
Figure 1-7 shows the key hardware components on the rear panel of an
AMS 2100 base unit. Except for the number of Fibre channel host
connectors on the controllers, the AMS 2100 rear panel is identical to the
AMS 2300. The two base units in each model array are identical and can be
installed in either slot. The base units for the AMS 2100 and the AMS 2300
are described separately in this chapter.
